Vulnerability of Jews to affective disorders.

OBJECTIVE: Psychiatric literature over the past 100 years suggests that Jews are at higher risk for affective disorders than numbers of other religious groups. To examine these claims, the authors analyzed data from the National Institute of Mental Health Epidemiologic Catchment Area (ECA) study. In addition, the relationships among gender, alcoholism, and major depression were investigated. METHOD: The period prevalence and lifetime rates of DSM-III major depression among Jews, Catholics, Protestants, individuals in other religious groups, and individuals with no religious affiliation were examined in the Los Angeles and New Haven, Conn., ECA data. Logistic regression with covariates for site, gender, marital status, and socioeconomic status was used to estimate odds ratios and 95% confidence intervals. The calculated rates, based on the combined data from ECA study waves 1 and 2 for the white population, were weighted according to the 1980 U.S. population census. Female-to-male rate ratios and rates of alcohol abuse/dependence were also obtained. RESULTS: While no differences were found among females, Jewish males had significantly higher rates of major depression than Catholics, Protestants, and all non-Jews combined. Jews had a 1:1 female-to-male ratio for major depression, in contrast to the other religious groups, which approached the universal 2:1 ratio. Rates of alcohol abuse/dependence were inversely related to rates of major depression. CONCLUSIONS: The results support only in part the earlier reports that Jews have higher rates of depression. The equal gender distribution of major depression among Jews may be associated with the lower rate of alcoholism among Jewish males.

High incidence of myeloproliferative disorders in Ashkenazi Jews in northern Israel.

We have analysed epidemiological parameters in 339 patients with myeloproliferative disorders (MPD) diagnosed in northern Israel between 1975 and 1989 as having polycythemia vera (191 patients), agnogenic myeloid metaplasia (AMM) (113) and essential thrombocythemia (ET) (36). Mean average annual incidence was 11.4 per 1 million residents for polycythemia vera, 6.5 for AMM and 2.1 for ET. For all three diseases the average annual incidence increased with age and was 10 times higher in patients over 65 years compared to those less under the age of 45 years. Four percent of all patients had relatives with MPD. Incidence of MPD in Jews was 10 fold higher than expected compared to Arabs and this difference was noted for all 3 diseases. The incidence in Ashkenazi Jews originating from eastern and central Europe, was 10 and 20 folds higher than in Sephardic Jews and Arabs respectively. Mean age at diagnosis of MPD in Arabs and Sephardic Jews was lower than in Ashkenazi Jews (52 and 56 years compared to 64 years P < 0.05). Likewise, mean age at diagnosis was lower in the 11.5% of MPD patients with prior exposure to biological or chemical hazards compared to unexposed individuals (58 years versus 63 years, P < 0.02). These data demonstrate a cluster of MPD in Ashkenazi Jews in northern Israel and emphasize the importance of genetic predisposition possibly interacting with acquired factors in the pathogenesis of these disorders.

Haplotype VIII of the Y chromosome is the ancestral haplotype in Jews.

DNA samples from Ashkenazic and Sephardic Jews were studied with the Y-chromosome-specific DNA probes p49f and p49a to screen for restriction fragment length polymorphisms and haplotypes. Two haplotypes (VII and VIII) are the most widespread, representing about 50% of the total number of haplotypes in Jews. The major haplotype in Oriental Jews is haplotype VIII (85.1%); haplotype VIII is also the major haplotype in the Djerban Jews (77.5%) (Djerban Jews represent probably one of the oldest Jewish communities). Together these results confirm that haplotype VIII is the ancestral haplotype in Jews.

Beliefs about alcohol among UK Jews and Protestants: do they fit the alcohol-depression hypothesis?

BACKGROUND: Some research has suggested that Jews drink less alcohol than other cultural groups, and may have different beliefs about its use. Differences in beliefs about alcohol, and different patterns of use, may play a role in accounting for cultural and gender variations in depression prevalence. Alcohol may act as an escape route from depression, thus deflating depression rates in certain groups of people, in particular, men from Protestant backgrounds. METHODS: Self-reported use and beliefs about alcohol were assessed in a UK sample of 70 Jews and 91 Protestants, including non-practising people of Jewish and Protestant background. The effects of religious group and of gender on measures of alcohol behaviour and beliefs were examined. RESULTS: Some differences were found between Jews and Protestants. Jews had less favourable beliefs about alcohol and drank less than Protestants. More importantly, and in line with our hypotheses, there were gender differences in Protestants but not Jews with respect to some beliefs about alcohol and actual use of alcohol. CONCLUSIONS: The study goes some way in supporting the notion that religious-cultural and gender differences in beliefs and behaviour towards alcohol may contribute to religious-cultural and gender differences in rates of depression.

Diagnostic x-rays and risk of epithelial ovarian carcinoma in Jews.

PURPOSE: To test the hypothesis that there would be ethnic differences in susceptibility to ionizing radiation from diagnostic x-rays. METHODS: In a hospital-based study we compared reports of diagnostic x-rays to the lower abdomen and pelvis in incident cases of epithelial ovarian carcinoma (N = 161), community controls (N = 156) and convenience controls (N = 87). RESULTS: Thirty-nine per cent of cases and 31% of controls recalled x-rays more than 10 years before; 27% of cases and 14% of controls reported four Jewish grandparents. Comparing the cases with community controls, the odds ratio (95% confidence interval) for Jews versus non-Jews among women reporting no x-rays was 1.02 (0.37-2.79); among women reporting x-rays the estimate for Jews was 8.91 (2.00-39.6). Consistent results were seen with inclusion of convenience controls. Jewish cases reported an excess of pelvic diagnostic x-rays from age 20 onward and an excess of barium enemas and pyelograms. CONCLUSIONS: These preliminary findings require confirmation in other studies. They suggest that the known excess risk of this carcinoma in Jews might be associated with exposure to x-rays and add to a previous observation of an altered susceptibility to ionizing radiation in Jews. If confirmed, they would suggest a need for continued vigilance to evaluate the risks and benefits of diagnostic x-rays in individuals, regardless of ethnic origin, who might carry mutations in DNA repair genes.

Intelligence differences between European and oriental Jews in Israel.

A number of studies have found that Ashkenazi Jews in the United States have a high average IQ. It has been proposed by Cochran, Hardy and Harpending (2006) that this can be explained by the occupational constraints imposed on the Ashkenazi for many centuries in Europe, when they were largely confined to money-lending. They propose that this selected for the high verbal and mathematical intelligence that has several times been found in American Ashkenazim. The current study investigates how far this theory holds for European and Oriental Jews in Israel. A review of studies shows that Oriental Jews in Israel have an average IQ 14 points lower than that of European (largely Ashkenazi) Jews. It is proposed that this difference can be explained in terms of the Cochran, Hardy and Harpending theory because Oriental Jews were permitted to engage in a much wider range of occupations and hence did not come under the selection pressure to develop the high verbal and mathematical intelligence that was present for Ashkenazim.

Mutation of the prion protein in Libyan Jews with Creutzfeldt-Jakob disease.

BACKGROUND: Creutzfeldt-Jakob disease is a transmissible neurodegenerative disorder that occurs more than 100 times more frequently among Libyan Jews than in the worldwide population. We examined 11 patients with the disease--10 Libyan Jews from Israel and 1 Libyan Jew from Italy--to determine whether abnormalities of the prion protein could be detected in them. Abnormal forms of this host-encoded protein are the predominant if not sole components of the transmissible agent that causes the disease. METHODS: The prion-protein open-reading frame in peripheral-leukocyte DNA from the Italian patient was amplified with the polymerase chain reaction and sequenced. Allele-specific oligonucleotide hybridization was used to assess a prion-protein codon 200 lysine mutation in the 10 Israeli patients and 37 control subjects. RESULTS: The prion-protein sequence in DNA from the Italian patient revealed a single nucleotide change (G----A) at the first position of codon 200 that resulted in a substitution of lysine for glutamate. This substitution was detected in all 10 Israeli patients, 8 of whom had a positive family history of Creutzfeldt-Jakob disease. One patient was homozygous for the lysine mutation, and her clinical course did not differ from that of the patients heterozygous for the mutation. The lysine mutation was not found in one Moroccan Jew from Israel with Creutzfeldt-Jakob disease. CONCLUSIONS: The codon 200 lysine mutation of the prion-protein gene is consistently present among Libyan Jews with Creutzfeldt-Jakob disease, strongly supporting a genetic pathogenesis of their illness. The similarity of the clinical courses of the patient homozygous for this mutation and the patients heterozygous for it argues that familial Creutzfeldt-Jakob disease is a true dominant disorder.

The blood groups and other heriditary blood factors of Yemenite and Kurdish Jews.

Blood specimens collected fro Yemenite and Kurdish Jews living in Israel were tested for 11 blood group systems 5 plasma protein systems and 9 systems of red-cell enzymes. The results of these tests were combined with those of tests on other Yemenite and Kurdish Jews, reported by Godber et al. (1973), the total data sorted according to the place of origin of the subjects or their parents in the Yemen Arab Republic and Kurdistan respectively. Gene frequencies were calculated for each of the local populations so defined. It is confirmed that the Yemenite Jews show a close relationship to the Yemenite Arabs, but those from the southern part of the Yemen Arab Republic have a higher frequency of African marker genes than those in the north. The Habbanite Jews have a similar rather high frequency of African genes (Bonné et al., 1970). The Kurdish Jews from Iran and northern-western Iraq show a moderate genetic resemblance to the indigenous Kurds of Iran, while those from south-eastern Iraq differ considerably, especially in their low frequency of A1, high B, high CDe (R1) and low cde (r).

The Y chromosome pool of Jews as part of the genetic landscape of the Middle East.

A sample of 526 Y chromosomes representing six Middle Eastern populations (Ashkenazi, Sephardic, and Kurdish Jews from Israel; Muslim Kurds; Muslim Arabs from Israel and the Palestinian Authority Area; and Bedouin from the Negev) was analyzed for 13 binary polymorphisms and six microsatellite loci. The investigation of the genetic relationship among three Jewish communities revealed that Kurdish and Sephardic Jews were indistinguishable from one another, whereas both differed slightly, yet significantly, from Ashkenazi Jews. The differences among Ashkenazim may be a result of low-level gene flow from European populations and/or genetic drift during isolation. Admixture between Kurdish Jews and their former Muslim host population in Kurdistan appeared to be negligible. In comparison with data available from other relevant populations in the region, Jews were found to be more closely related to groups in the north of the Fertile Crescent (Kurds, Turks, and Armenians) than to their Arab neighbors. The two haplogroups Eu 9 and Eu 10 constitute a major part of the Y chromosome pool in the analyzed sample. Our data suggest that Eu 9 originated in the northern part, and Eu 10 in the southern part of the Fertile Crescent. Genetic dating yielded estimates of the expansion of both haplogroups that cover the Neolithic period in the region. Palestinian Arabs and Bedouin differed from the other Middle Eastern populations studied here, mainly in specific high-frequency Eu 10 haplotypes not found in the non-Arab groups. These chromosomes might have been introduced through migrations from the Arabian Peninsula during the last two millennia. The present study contributes to the elucidation of the complex demographic history that shaped the present-day genetic landscape in the region.

Fighting colorectal cancer: molecular epidemiology differences among Ashkenazi and Sephardic Jews and Palestinians.

BACKGROUND: To evaluate and compare differences in the molecular genetics among high-risk (Ashkenazi Jews), intermediate-risk (Sephardic Jews) and low-risk (Palestinians) groups for colorectal cancer who live in the same geographical region. PATIENTS AND METHODS: The 1995-1996 records from the Tel Aviv Medical Center and Muqased hospital (East Jerusalem) randomly identified patients with colorectal cancer. There were 25 patients from each ethnic group. Epidemiological data were obtained from interviews with the patients and from their hospital charts. The levels of cyclin D1, beta-catenine, p27, p53, Ki-67 and Her-2/neu proteins were determined by immunohistochemistry. The main outcome measures were the association between gene expression and colorectal incidence in the different ethnic groups. RESULTS: Ashkenazi Jews have the highest rate of colorectal cancer, and are diagnosed at an early stage compared with Palestinians (72% and 33% of the cases are in Dukes' A and B, respectively), and, hence, this may explain the better 5-year survival rate among this group. Sephardic Jews are diagnosed at a more advanced stage, the tumors are poorly differentiated and they lack p27. Palestinians have significantly higher cyclin D1 levels. There was a statistically significant inverse correlation between the expression of beta-catenine and cyclin D1, as well as p53 and p27 (P <0.05). CONCLUSIONS: Increased expression of cyclin D1, p53, Ki-67, beta-catenine and Her-2/neu, and decreased expression of p27 may be important events in the three ethnic groups with colorectal cancer. The lower mortality rate among Ashkenazi Jews may be partially explained by their better molecular biology profile.

A mutation in LMAN1 (ERGIC-53) causing combined factor V and factor VIII deficiency is prevalent in Jews originating from the island of Djerba in Tunisia.

Combined deficiency of factor V and factor VIII is a rare autosomal recessive bleeding disorder that is caused by mutations in the LMAN1 or MCFD2 genes. These genes encode for proteins that form a complex that takes part in the transport of factor V and factor VIII from the endoplasmic reticulum to Golgi. Two mutations in LMAN1 have been observed in Jews: a guanine (G) insertion in exon 1 among Middle Eastern Jewish families, and a thymidine (T) to cytosine (C) transition in intron 9 at a donor splice site among Tunisian families. For each mutation, haplotype analysis revealed a founder effect. Because all affected Tunisian families belong to an ancient Jewish community in the island of Djerba off the coast of Tunisia, we screened members of this community for the intron 9 T --> C transition. Among 233 apparently unrelated individuals five heterozygotes were detected, predicting an allele frequency of 0.0107 (95% confidence interval, 0.0035-0.0248), while among 259 North African Jews none was found to carry the mutation. The prevalence of the mutation in Djerba Jews is consistent with the observation that all affected Tunisian Jewish families have origins in Djerba and with the finding of a common haplotype for the 9 + 2 T --> C mutation. The G insertion in exon 1 was found in one of 245 Iraqi Jews, predicting an allele frequency of 0.0022 (95% confidence interval, 0.0001-0.0123), but in none of 180 Iranian Jews examined. In view of the relatively low frequency of the mutations in the respective populations it seems reasonable to advocate carrier detection and prenatal diagnosis only in affected families.

Classic Kaposi's sarcoma in Jews living in Israel, 1961-1989: a population-based incidence study.

BACKGROUND: The incidence of classic Kaposi's sarcoma (CKS) has been reported to be high in Jewish populations, mostly born in Eastern Europe. OBJECTIVE: To describe the incidence on CKS in Israeli Jews and to determine differences in incidence according to their geography origin. DESIGN: We analysed data on 1098 incident CKS cases with known country of origin occurring between 1961 and 1989 in the Jewish Israeli population. Reporting systems were the Israel Cancer Registry, the medical documentation of all-Kaposi's sarcoma cases and the registry of HIV-seropositive patients. Patients who were seropositive for HIV were excluded from the study population. Population figures for groups of migrants and natives were derived from census surveys (1961, 1972, 1983) and inter-census estimates based on the population registry. RESULTS: The overall age-standardized rate of CKS was 16.9 per million in men and 6.3 per million in women. The ratio between genders remained stable during the study period. In both genders, there was a steep increase in CKS incidence between the late 1960s (age-standardized rates per million: 8.0 in men and 2.2 in women) and the early 1970s (17.9 in men and 6.7 in women). No further increase was present after 1971. Overall, immigrants experienced a relative risk (RR) of 1.17 [95% confidence interval (CI) 0.90-1.521 compared with Jews born in Israel. Immigrants from Morocco, Algeria and Tunisia had the highest incidence (RR 2.01; 95% CI 1.52-2.65) compared with Jews born in Israel, followed by those born in Iraq (RR 1.74; CI 95% 1.27-2.37). The lowest incidence was experienced by immigrants from Iran (RR 0.37; CI 95% 0.18-0.77) and from Central European countries (RR 0.45; CI 95% 0.30-0.66). Immigrants from other countries in Asia, Africa, the Americas and Europe had similar rates as Jews born in Israel. CONCLUSIONS: Israeli Jews present one of the highest incidences of CKS reported from developed countries. The incidence varies according to geographical origin. Countries surrounding the Mediterranean sea represent the area of highest CKS incidence.

HLA DR and DQ polymorphism in Ashkenazi and non-Ashkenazi Jews: comparison with other Mediterraneans.

HLA-DR and DQ alleles have been detected by DNA typing in Ashkenazi and non-Ashkenazi Jews from Israel. Allele frequencies, characteristic DR/DQ linkage disequilibria, population distances and their corresponding dendrogram by using the Neighbor-Joining method were used to study relatedness between Jewish and other Mediterranean and non Mediterranean populations. Closest relatedness is observed between Ashkenazi and non-Ashkenazi Jews, and, in decreasing order, also with Algerians, Spaniards (including Spanish-Basques), French and Italians. Also, particular characteristic Central European alleles are observed in Ashkenazi Jews and Mediterranean/African alleles in non-Ashkenazi Jews. This is consistent with historical data, Jews being an ancient Mediterranean population, who have had a certain degree of admixture with their 2000-3000 years old neighbors in spite of cultural and religious traditions which have preserved identity outside Israel.

Inheritance of idiopathic torsion dystonia among Jews.

Idiopathic torsion dystonia (ITD) has long been considered to be genetically determined, but the pattern of inheritance has been unclear. It has been suggested that inheritance may differ in Jews and non-Jews. In the present study, data gathered in a nationwide survey of ITD in Israel were analysed. Between 1969 and 1980, 47 patients were collected, of whom 40 were of European origin. In these European Jews, the ITD frequency was about 1:23 000 live births, which was five-fold greater than in Jews of Afro-Asian origin. Assuming that all cases fit the same genetic model, an X linked or a simple autosomal recessive model of inheritance did not agree well with our data. An autosomal dominant model with low penetrance could have accounted for our observations and would yield an ITD gene frequency in European Jews of 3 to 4:100 000. In view of the increased ages of their fathers, the isolated cases may have included some new mutations. Multifactorial inheritance was also possible. However, it may be inappropriate to assume that all cases have the same genetic basis, or even that all are inherited.

Drowning your sorrows? Attitudes towards alcohol in UK Jews and Protestants: a thematic analysis.

BACKGROUND: Jewish culturally supported beliefs may discourage drinking and drunkenness as ways of socialising and coping with stress. Thus Jewish men under stress may be relatively more likely to become depressed, and less likely to use and abuse alcohol. This study is the first qualitative comparison of Jews and Protestants, men and women. It examines whether alcohol-related beliefs are consistent with the alcohol-depression hypothesis, i.e. that positive beliefs about alcohol use and effects are associated with high alcohol use and low depression. MATERIAL AND DISCUSSION: A thematic (interpretive phenomenological) analysis on open-ended question responses, from 70 Jews and 91 Protestants, and on semi-structured interviews with five Jews and four Protestants, identified three salient themes: the importance of retaining self-control; the pleasures of losing inhibitions; and the relations of alcohol-related behaviour to identity. Compared to Protestants, Jews described alcohol-related behaviour as threatening to self-control, loss of inhibition as unenjoyable and dangerous and distinguished between the kinds of drinking behaviours appropriate for Jews and others. Sub-themes for Protestant men were denial that drinking threatens self-control, and appropriateness of going to the pub. CONCLUSIONS: The themes identified are not measurable using published research instruments. Alcohol-related behaviour may be a feature of Jewish identity. The beliefs identified are consistent with the alcohol-depression hypothesis.

Population genetic studies on Jews. I. The alpha 2HS serum glycoprotein, a polymorphism strongly correlated with latitude.

A sample of Jews subdivided according to the birth-place of their parents or grand-parents have been examined for a large number of genetic markers in the course of a long-term project on the genetics of Jews. We report here the findings concerning 794 Jews studied for the AHSG polymorphism. All the subsamples were in Hardy-Weinberg equilibrium. A highly significant difference was found between Sephardic + Near East Jews and Ashkenazi (AHSG*2 frequencies: 0.184 +/- 0.015 and 0.258 +/- 0.016, respectively). For comparative purposes the data available on Caucasoids have been considered. It turned out that they were neatly arranged along a latitude-AHSG gene frequency cline (0.0092 of AHSG*2 gene frequency increase per degree of increase of latitude) in the explored 30 degrees-60 degrees range (r = 0.97; P much less than 0.001). Of the two Jewish frequencies that could be taken into consideration because of their sufficient sizes, that of the Near East + Sephardic Jews was perfectly in line with the above mentioned cline, while that of the Ashkenazi was somewhat displaced in the sense of being more similar than expected to the other, more southern, Jewish group. Since the only AHSG*2 frequency significantly displaced from the regression line is that of the Ashkenazi, whose ancestors lived until centuries ago in more southern areas, this finding is a strong confirmation of the observed cline.

The Jew in literature: the hated self.

This paper discusses the special psychological and sociological qualities of the Jew in the literature of novels, plays and short stories. From Shakespeare to Hemingway, the Jew has been assigned a special place in the psyche of the authors here described, reflecting the ongoing cultural bias as it became internalized in the selves of the authors quoted. The Jew of Shakespeare's "Shylock" reflects the 16th century bias of Shakespeare and is at a distance--although with interesting similarities--to the Jew of Hemingway. Two psychological facets of anti-Semitism in literature are primarily discussed: the group-self perception of the Jew as stereotype persona, identified over time with specific peculiarities, and the psychological perceptions (in the quoted literature) to the internalized group-percept.

The frequency of founder mutations in the BRCA1, BRCA2, and APC genes in Australian Ashkenazi Jews: implications for the generality of U.S. population data.

BACKGROUND: Several studies have shown that Ashkenazi Jews in the United States and Israel have a high prevalence of the founder mutations BRCA1 185delAG, BRCA1 5382insC, BRCA2 6174delT, and APC I1307K at frequencies of 1.0--1.1%, 0.2--0.3%, 0.6--1.4%, and 6.1--7.0%, respectively. The objective of this study was to compare the prevalence of these alleles in the Australian Jewish population with that of U.S. Jews. Australian Jews have a different history of migration, with less opportunity for changes in allele frequency due to conversion or intermarriage with non-Jewish Australians. The results obtained therefore can be used to assess whether U.S. data can be generalized to other Jewish populations. SUBJECTS AND METHODS. Subject samples were ascertained through a screening program for Tay-Sachs disease as part of a community-based screening program in New South Wales and Victoria. DNA extracted from 1200 deidentified blood samples was tested using amplification refractory mutation system polymerase chain reaction. RESULTS: The allele frequencies found were as follows: BRCA1 185delAG 1.25% (95% confidence interval [CI], 0.62--1.88%), BRCA1 5382insC 0.25% (95% CI, 0--0.53%), BRCA2 6174delT 1.08% (95% CI, 0.50--1.67%), and APC I1307K 8.67% (95% CI, 7.07--10.26%). The prevalence of breast carcinoma predisposition alleles therefore is greater than 2.5% in Australian Ashkenazim. CONCLUSIONS: There were no significant differences between the allele frequencies in Australian Ashkenazim and those identified in other studies with similar ascertainment strategies, despite the different migration patterns of Australian Jews. This suggests the broad applicability of the U.S. and Israeli data, not only to Australian Ashkenazim, but also to Ashkenazi communities throughout the world.
