The distribution of ABO, MNSs, Rhesus, Kell, Duffy and Kidd blood groups of Jews originating from 20 countries.

The distribution of red blood cell antigens of 10,000 Jewish Israeli men are presented by their country of birth. The ABO, MNSs, Rh, Kell, Duffy and Kidd blood groups were examined, and their frequencies were analyzed for each of 20 countries of birth. These results can serve as control and reference data for various studies, both basic and applied, concerning Jewish communities. The data are shown in various ways: phenotype and allele frequencies are presented alphabetically by countries of birth, and the allele frequencies are also shown by lowest to highest frequencies among the communities. The data indicate that Jews from Europe and Morocco tend to have intermediate allele frequencies. At the extremes are mainly Jews from Yemen, Aden and Yugoslavia. These observations are in accordance with previous studies on genetic distances.

Elevated frequency of Tay-Sachs disease among Ashkenazic Jews unlikely by genetic drift alone.

Using the steady-state distribution of recessive lethal gene the probability of finding the elevated frequency of Tay-Sachs (TSD) gene among Ashkenazic Jews is computed. For various estimated values of mutation rate and population size, this probability is found to be statistically significant. This probabiltiy, in fact, becomes even smaller if a steady influx of foreign genes into the Ashkenazic Jewish populations is considered. It is suggested that heterozygote advantage together with random genetic drift should be considered as the most probable mechansim for the elevation of TSD gene frequency among the Ashkenazic Jews.

Linkage disequilibrium between the FES, D15S127, and BLM loci in Ashkenazi Jews with Bloom syndrome.

Bloom syndrome (BS) is more common in the Ashkenazi Jewish than in any other population. Approximately 1 in 110 Ashkenazi Jews carries blm, the BS mutation. The locus mutated in BS, BLM, maps to chromosome subband 15q26.1, tightly linked to the proto-oncogene FES. We have investigated the basis for the increased frequency of blm in the Ashkenazim by genotyping polymorphic microsatellite loci tightly linked to BLM in affected and unaffected individuals from Ashkenazi Jewish and non-Ashkenazi populations. A striking association of the C3 allele at FES with blm (delta = .422; p = 5.52 x 10(-7)) and of the 145-bp and 147-bp alleles at D15S127 with blm (delta = .392 and delta = .483, respectively; p = 2.8 x 10(-5) and p = 5.4 x 10(-7), respectively) was detected in Ashkenazi Jews with BS. This linkage disequilibrium constitutes strong support for a founder-effect hypothesis: the chromosome in the hypothetical founder who carried blm also carried the C3 allele at FES and either the 145-bp or the 147-bp allele at D15S127.

Y-chromosome-specific haplotype diversity in Ashkenazic and Sephardic Jews.

DNA samples from Ashkenazic and Sephardic Jews were studied with Y-chromosome-specific DNA probes p49f and p49a to screen for RFLPs and haplotypes. All 16 European haplotypes were found in Jews, but only 2 of them (VII and VIII) were widespread. Haplotype distributions in the two Jewish populations are similar, but haplotypes XI and XV are more frequent in the Ashkenazim and haplotypes IV and V are more frequent in the Sephardim, indicating their origins.

The epidemiology of benign leukopenia in Yemenite Jews.

Blood counts of 372 Yemenite Jews of all ages were reviewed in order to clarify the epidemiology of benign leukopenia. Twenty-one percent of the total leukocyte counts were below 5.0 x 10(3) cells/mm3. Neutropenia < 2.0 x 10(3) was present in 15.4% of the blood counts, significantly lowering the average neutrophil count in the population. There was no significant variation in the prevalence of neutropenia with age. In contrast, the average lymphocyte and erythrocyte counts were normal. We conclude that leukopenia among Yemenite Jews should be defined as neutropenia rather than leukopenia, and that the phenomenon is only half as common as was previously noted. Since the prevalence of neutropenia remains constant across all age-groups, in immigrants as well as among the Israeli-born, it is unlikely to be an acquired condition.

Endemic goiter in Ethiopian Jews--possible pathogenetic factors.

Goiter size, thyroid function tests and thyroid cytology were studied in 100 immigrant Ethiopian Jews, 1-12 months after arrival in Israel on Operation Solomon (1991), who were referred for evaluation of goiter. Female-to-male ratio was 2.2:1. Hypothyroidism was rare (1%) whereas hyperthyroidism was frequently diagnosed (11%). Elevated thyroglobulin (TG) serum levels were found in 36% of the patients. Antithyroid antibodies were not detected. Thyroid cytology revealed rich colloid goiters in all patients. Thyroid carcinomata and chronic lymphocytic thyroiditis were not diagnosed. Both hyperthyroidism and elevated TG levels were found only in female patients and were equally distributed in patients maintained on either Israeli or Ethiopian diets. It is suggested that the major factors in the pathogenesis of endemic goiter in Ethiopian Jews are genetic and/or food goiterogens, with only a minor role for iodine deficiency.

Predisposition to the fragile X syndrome in Jews of Tunisian descent is due to the absence of AGG interruptions on a rare Mediterranean haplotype.

We have studied the ethnic distribution of the fragile X syndrome in Israel and have found that 36/136 (26.5%) of apparently unrelated pedigrees were of Tunisian Jewish descent. The Tunisian Jews, however, constitute only 2%-3% of the general Israeli population, identifying the first ethnic group significantly (P < .001) predisposed to the development of this disease. Associated with this increase in disease prevalence, we have found an unusually high incidence of FMR1 CGG repeats devoid of AGG interruptions among the normal Tunisian Jewish population (30/150, or 20.0%). Furthermore, the proportion of these alleles beyond the FMR1 CGG repeat instability threshold (>35 repeats) (8/150, or 5.3%) was significantly greater (P < .04) than that proportion found among non-Tunisian Jewish controls in Israel (1/136). Haplotype analysis has indicated that these large uninterrupted CGG repeat alleles are present on a previously unreported (DXS548-FRAXAC1-FRAXAC2) haplotype that accounts for all observed cases of disease among Tunisian Jewish X chromosomes. The high prevalence of disease among Tunisian Jews, we suggest, is due to a founder effect of this rare haplotype, which is completely devoid of AGG interruptions in the Jewish population of Tunisia.

Glanzmann thrombasthenia caused by an 11.2-kb deletion in the glycoprotein IIIa (beta3) is a second mutation in Iraqi Jews that stemmed from a distinct founder.

Glanzmann thrombasthenia (GT) is a rare bleeding disorder resulting from mutations in either glycoprotein (GP) IIb or GPIIIa genes. The disease is relatively frequent in highly inbred populations such as Iraqi Jews. The molecular basis of GT in 6 unrelated Iraqi-Jewish patients was previously identified as an 11-bp deletion in exon 12 of the GPIIIa gene. We now describe a second mutation found in 3 unrelated Iraqi-Jewish families that consists of an 11.2-kb deletion between an Alu repeat in intron 9 and exon 13 of the GPIIIa gene. The mutant DNA is transcribed into mRNA in which exons 10 through 13 are absent. Splicing of exon 9 directly to exon 14 leads to a shift in the reading frame resulting in a stop codon. The predicted protein is truncated in the middle of the third cysteine-rich domain before the transmembrane domain. Simple DNA-based methods were devised for identification of both mutations in Iraqi Jews for the purpose of carrier detection and prenatal diagnosis enabling prevention of GT. A survey of the general Iraqi-Jewish population for the first 11-bp deletion and the second 11.2-kb deletion disclosed that the allele frequency of the first mutation was 0.0043, whereas none of 700 individuals examined bore the second mutation (allele frequency <0.0007). Among 40 GT patients of Iraqi-Jewish origin 31 were homozygous for the first mutation, 4 were compound heterozygotes for the first and second mutations, and 2 were homozygous for the second mutation. Haplotype analyses using 4 polymorphic markers in the GPIIIa gene showed that each mutation originated in a distinct founder.

Unsaturated fatty acids in adipose tissue of Israeli Jews.

The ratio of polyunsaturated to saturated fatty acids in the adipose tissue of Israelis was found to be 0.88 for Ashkenazic Jews and 1.13 for non-Ashkenazic Jews, the highest reported for any population on a free-choice diet. Despite the unusually high ratios, indicating a high consumption of polyunsaturated fat, there is nevertheless, a relatively high incidence of ischemic heart disease among Israelis.

Clinical differences between North African and Iraqi Jews with familial Mediterranean fever.

Familial Mediterranean fever (FMF) is an autosomal recessive disease causing attacks of fever and serositis. The gene causing this disease, designated MEFV, was mapped to the short arm of chromosome 16, but has not yet been cloned. North African and Iraqi Jews constitute the two largest population groups suffering from the disease in Israel. In this report we compared the severity of the disease between these two populations. North African Jews were found to have a more severe disease manifested by an earlier age of onset, an increase in frequency and severity of joint involvement, a higher incidence of erysipelas-like erythema, and a higher dose of colchicine required to control symptoms. The involvement of additional genes, environmental factors, and different mutations in MEFV, may explain the clinical variation in disease severity between these two population groups.

Quality indices of Jew's mallow and spinach during frozen storage.

In this study, Jew's mallow and spinach were heat treated and kept frozen, at -18 degrees C, for 3 months. Analysis of some chemical components and enzymatic activities as well as a sensory evaluation were undertaken. At the end of the storage period, blanched spinach showed no PPO (polyphenyloxidase) activity at all, but still contained PO (peroxydase) and LO (lipoxygenase) activities. The untreated spinach stored under the same conditions showed high activities of PO, PPO and LO. The heat treated mallow still contained high enzyme activities which decreased slowly during frozen storage. Statistical analysis of the chemical composition and the sensory evaluation results indicated that heat treatments of mallow caused significant differences in total solids, pH, chlorophyll a and total chlorophyll, while frozen storage, of samples of the same treatment for 3 months caused no significant differences in moisture, ash, oxalic acid, pH, chlorophyll a and total chlorophyll. No significant differences could be noticed in the overall acceptability between mallow samples mixed with hot water and those mixed with a hot 0.1% MgCO3 solution. Significant differences were found between the heat treated and the untreated mallow. Changes of the chemical composition and the overall acceptability of blanched spinach during frozen storage showed almost the same trend noticed for the Jew's mallow.

Making technology familiar: orthodox Jews and infertility support, advice, and inspiration.

This paper examines how orthodox Jews use traditional strategies and new media simultaneously to cope with infertility in the age of new reproductive technologies. Not only have they used the Internet to establish support, information, and educational networks, but also they have created frameworks for unique professional collaborations among rabbis, doctors, and clinic personnel in order to ensure that their fertility treatments are conducted with strict attention to Jewish legal concerns, particularly with regard to incest, adultery, and traditional practices regarding bodily emissions. Throughout these processes, they have innovated a hybrid language for describing and explaining infertility treatments that blends Hebrew prayers, Yiddish aphorisms, English slang, Gematria (numerology), and biomedical terminology. By using idiomatic language and folk practice, orthodox Jews construct a unique terrain that shapes and makes familiar their experience and understanding of fertility treatment. Biomedicine in this context is understood as a set of tools and strategies that can be readily appropriated and harnessed to a particular set of individual and collective goals.

Religiosity and obsessive-compulsive behavior in Israeli Jews.

Individual differences in obsessive-compulsive (OC) behavior in various cultures correlate with religiosity. The current paper explored the so far unstudied relationship between religiosity and OC behavior in Israeli Jews. Two studies were conducted. Study 1 focused on the relationship between religiosity and OC behavior in a representative sample of Israeli students. Study 2 focused on religious change and OC behavior in a non-random sample of 31 individuals who had become more religious (the MR group), and 30 individuals who were less religious (the LR group) than their parents. Instruments used were the Maudsley obsessive-compulsive inventory (MOCI), the student religiosity questionnaire, and questions about parental home observance, upbringing, and changes in religiosity. In the first study, no association was found between religiosity and OC behavior. Religiosity was related to some degree to perfectionism and to the parental attitude to upbringing. In the second study, a significant difference was observed between the MR and the LR groups on OC behavior as measured by the MOCI. Conclusion, among Israeli Jews a lot of religious observance is non-reflective, and is not associated with individual differences in personality or OC symptoms. Those who undergo religious change may do so in response to their behavioral propensities. One such path is that the more OC become MR, and the less OC less religiously observant.

Is thought-action fusion related to religiosity? Differences between Christians and Jews.

The purpose of this study was to evaluate the relationship between thought-action fusion (TAF) and religiosity in Christians and Jews (Orthodox, Conservative, and Reform). There is a growing body of evidence that suggests that religiosity is related to obsessive cognitions in Christian samples, but conceptual and empirical ambiguities complicate the interpretation of that literature and its application to non-Christian groups. As predicted on the basis of previous research, Christians scored higher than Jews on moral TAF. This effect was large and not explained by differences in self-reported religiosity. The Jewish groups did not differ from each other. Furthermore, religiosity was significantly associated with TAF only within the Christian group. These results qualify the presumed association between religiosity and obsessive cognitions. General religiosity is not associated with TAF; it rather depends on what religious group. Moreover, large group differences in a supposed maladaptive construct without evidence of corresponding differences in prevalence rates call into question the assumption that TAF is always a marker of pathology.

Apolipoprotein Eepsilon4 allele, a risk factor for late onset nonfamilial Alzheimer's disease among Israeli Jews.

Apolipoprotein (apoE) genotypes were determined in 90 Israeli Jews with late onset sporadic Alzheimer's Disease (AD) and in 90 age- and sex-matched non-demented controls. The percentage of subjects carrying at least one apoEepsilon4 allele was 6% among the controls, and 42% among the patients (P<0.001), indicating a strong association between late onset sporadic AD and the apoEepsilon4 allele. However, no association was found between the apoEepsilon4 allele in demented and non-demented Jewish Israeli patients with Down's syndrome or Creutzfeldt-Jakob disease (CJD). The data presented in this paper confirmed several recent reports, suggesting that the apoEepsilon4 allele is a risk factor for the development of AD but not for the development of CJD or Down's syndrome among Israeli Jews.

Dried green leaf powders of Jew's mellow (Corchorus), persimmon (Diosphyros kaki) and sweet potato (Ipomoea batatas poir) lower hepatic cholesterol concentration and increase fecal bile acid excretion in rats fed a cholesterol-free diet.

A cholesterol-free diet containing dried powder of Jew's mellow leaves, persimmon leaves or sweet potato leaves respectively at 5% level as dietary fiber was fed to male Sprague-Dawley rats for about one month. The experiment was conducted twice except for sweet potato leaves. In the groups fed the diet mixed with powders of any of the three different dried green leaves, the hepatic cholesterol concentration significantly decreased. Such lowering was not observed in serum cholesterol concentration compared with the control (cellulose) group. A significant increase in fecal weight was observed in all the groups fed the green leaf samples. All the dried green leaves increased fecal excretion of bile acids per gram or per day compared with the control group in both experiments, but only the dried Jew's mellow leaves showed an increased excretion of neutral sterols. These results suggest that lowering of hepatic cholesterol by powdered green leaves is not necessarily due to the same factor, but to the increased fecal excretion of bile acids due to inhibited enterohepatic circulation in animals given these samples.

The Tyr978X BRCA1 Mutation in Non-Ashkenazi Jews: Occurrence in High-Risk Families, General Population and Unselected Ovarian Cancer Patients.

Background: In Jewish individuals of Ashkenazi (East European) decent, three predominant mutations, 185 delAG and 5382insC (BRCA1) and 6174delT (BRCA2), seem to account for a substantial portion of germline mutations in high-risk breast/ovarian cancer families. Among non-Ashkenazi Jews, the 185delAG and the Tyr978X mutations, as well as several 'private' mutations have been reported within the BRCA1 gene. Objective: Assessing the occurrence rate of the Tyr978X BRCA1 germline mutation in Jewish non-Ashkenazi individuals: high-risk familial cases, unselected ovarian cancer patients and the general average risk Jewish Iraqi population. In addition, finding proof that this is a founder mutation. Methods: PCR amplification of the relevant fragment of the BRCA1 gene from constitutional DNA followed by restriction enzyme digest that differentiates the wild type from the mutant allele. In addition, BRCA1-linked markers were used for haplotype analysis. Results: The Tyr978X BRCA1 mutation was detected in 3/289 (1%) of the average-risk Jewish Iraqi population, in 7/408 (1.7%) high-risk Jewish non-Ashkenazi individuals (representing 332 unrelated families) and in 1/81 (1.2%) of unselected Jewish non-Ashkenazi ovarian cancer patients. Allelotyping using BRCA1-linked markers revealed an identical allelic pattern in all mutation carriers with the intragenic markers. Conclusions: Our findings suggest that this mutation is prevalent in Iraqi Jews, represents a founder mutation, and should be incorporated into the panel of mutations analyzed in high-risk families of the appropriate ethnic background.

Molecular basis of heat labile hexosaminidase B among Jews and Arabs.

Genotyping individuals for Tay-Sachs disease (TSD) is mainly based on the heat lability of beta-hexosaminidase (Hex) A (alphabeta) and the heat stability of Hex B (betabeta). Mutations in the HEXB gene encoding the beta-subunits of Hex that result in heat-labile Hex B thus may lead to erroneous enzymatic genotyping regarding TSD. Utilizing single strand conformation polymorphism (SSCP) analysis for all 14 exons of HEXB followed by direct sequencing of aberrant fragments, we screened individuals whose Hex B was heat labile. A novel heat labile mutation, previously concluded to exist in the HEXB gene, was identified among Jews and Arabs as 1627 G-->A. One individual with heat labile Hex B (HLB) was negative for this novel mutation and for the known 1514 G-->A HLB mutation, proving that there exists at least one other unidentified HLB mutation. Based on these results, it is advisable to perform DNA tests for 1627 G-->A mutation in suspected HLB individuals.
