[Dermatoglyphics in beta-thalassemia major].

The features of dermatoglyphics in 39 children with beta-thalassemia major and in 47 their parents are studied. The control were 70 healthy children. The patients with beta-thalassemia had more often the prevailence of whorls over other finger patterns. There was an increase of the "atd" angle and some increase in the ridge of counts. Parents had also an increase of the amount of whorls, but this increase was less pronounced than under beta-thalassemia. The changes of the dermatoglyphics in parents of children affected with beta-thalassemia major are suggested to ba a phenotypic feature of heterozygous carrier of the mutant gene.

Palmar and digital dermatoglyphics of indigenous black Zimbabweans.

BACKGROUND: Dermatoglyphic traits have been shown to be genetically determined, conservative in their evolution, and different between and within population groups. There have been a few reports dealing with Southern African populations, but there appears to be no published report for indigenous black Zimbabweans. MATERIAL/METHODS: Bilateral palmar and digital prints of 270 indigenous black Zimbabweans were recorded, studied and classified using standard methods. The total finger ridge count (TFRC), pattern intensity index (PII), atd angle, and a-b ridge counts were analyzed and the data compared with those of Malawians, South African Zulus and Nigerian Yorubas. RESULTS: Ulnar loops were the most predominant digital pattern type in both sexes followed by whorls in males and arches in females. Females had significantly higher atd angles than males (p<0.01). Significant differences were also demonstrated between Zimbabwean and Malawian females, and between Zimbabwean and Yoruba men in TFRC and a-b ridge counts. Similarly significant differences were observed between Zimbabwean and Malawian males, male Zimbabweans and Yoruba, and male Zulus and Yorubas in atd angle and a-b ridge counts (p<0.001). CONCLUSIONS: This study documents similarities in digital ridge patterns between Zimbabweans, Malawians, and to some extent South African Zulus, indicating their close historical and anthropological relationship. However, Zimbabweans could be differentiated from the other population groups using certain dermatoglyphic traits. Nevertheless, all the groups showed some features common to other black Africans.

Latent structure of quantitative dermatoglyphic traits of middle Dalmatia (Croatia).

The latent structure of quantitative dermatoglyphic traits has been analyzed from the population in Middle Dalmatia: islands of Brac, Hvar and Korcula, peninsula of Peljesac and Makarska coastal region. We analyzed 18 variables from fingers and palms, and principal component analysis was performed. In males, we extracted 4 factors for the islands Brac and Korcula, 5 factors for the island of Hvar and Peljesac peninsula and 6 factors for Makarska coastal region. In females we extracted 4 factors for the island of Korcula, 5 factors for the island of Brac, Hvar and Peljesac peninsula, 6 factors for the Makarska region. The total variance in males varies for 4 factors, from 64.19% to 70.71% (for all factors from 68.88% to 75.80%). In females, for 4 factors the total variance was from 57.03% to 66.87% (for all factors from 66.87% to 76.13%). In all population groups on the first factor all finger dermatoglyphics were extracted, while on the other factors there is evident variability of a number of factors extracted and variable explanations. The analysis of variables from extracted factors might give us information about similarities and differences between the groups concerning the latent structure, and also the differences and inter-individual variability in females in comparison to the males. This study provides an insight into the effects of population structure and microevolution on quantitative variation.

Dermatoglyphs of digito-palmar complex in autistic disorder: family analysis.

AIM: To examine the role of the genetic component in the quantitative dermatoglyphic traits of autistic patients and their families, and the transmission of the autism. METHODS: Finger and palm prints were taken from 120 autistic patients (92 males and 28 females), their parents (92 mothers and 70 fathers), 32 healthy brothers and 28 sisters, as well as 400 healthy controls (200 males and 200 females). An analysis of quantitative traits of dermatoglyphs on the fingers (FRC - finger ridge count) and palms (a-b, b-c, and c-d ridge count, and atd angle) was performed. Descriptive statistics, multivariate analysis of variance (MANOVA) with Tukey HSD post hoc test, and discriminant analysis were used to determine the differences among the groups. In addition, correlations among family members were analyzed. RESULTS: Multivariate analysis showed significant differences among examined groups of autistic patients and their family members and healthy volunteers regarding both group membership and sex. Autistic male patients differed significantly from the healthy controls in the ridge count (RC) on the fourth and fifth finger, and in a-b RC and atd angle of both hands. Healthy fathers of autistic patients differed in atd angle, and brothers of autistic patients differed in all palmar variables from the healthy control group. Mothers of autistic patients differed significantly from the healthy female controls in the RC of the first, fourth, and fifth finger, in a-b and c-d RC on the palms, and atd angle of both hands. The first two discriminant functions explained 85.4% of variance and separated groups clearly in two ways: the first function separated healthy controls from family members of autistic patients, and the second one males from females. Interfamilial analysis showed significant interclass correlations between autistic sons and their mothers or fathers in practically all variables. However, the correlation between parents and their autistic daughters was lower. Both mothers and fathers of autistic patients correlated with their healthy children only in palmar variables. CONCLUSIONS: We found significant differences in ridge counts on the fingers and palms between the affected patients and their healthy controls, but these differences also existed between family members of autistic patients and healthy controls. Particularly pronounced were the differences between healthy female controls and female family members, including not only autistic female patients, but also their healthy mothers and sisters. Since the mothers and their autistic sons showed higher statistically significant correlation in most of the examined variables, unlike the mothers and their autistic or healthy daughters, it is possible that there is a connection between a recessive X-chromosome linkage, as a genetic component in the etiology of autistic disorders, and the influence of the inactivation of the affected X-chromosome in the females.

Dermatoglyphs and gastric cancer.

Gastric cancer is very common malignant disease, etiology of which is still unknown. Some studies consider that it is caused by a joint activity of both genetic and environmental factors. Digito-palmar dermatoglyphs were already used to determine hereditary base of some malignant diseases (breast, lung and colorectal cancer) and it was the reason for investigations of the correlation of their quantity features at patients with gastric cancer (36 males and 32 females) and the control groups of phenotypically healthy persons (50 males and 50 females). By performing statistical data processing of the multivariate and univariate analysis, as well as of discriminant ones, it was possible to prove the existence of heterogeneity between the investigated groups. Higher incidence of gastric cancer and the blood group A could be confirmed, as well. From the obtained findings can be concluded, that the results of quantitative analysis of digitopalmar dermatoglyphs affirm the existence of genetic predisposition for development of gastric cancer.

[Dermatoglyphics of the relatives of children with congenital developmental defects].

The localization of an axial triradius and the flexor creases were studied in 173 phenotypically normal mothers and 104 fathers of congenitally malformed children. The most pronounced changes of dermatoglyphics were found in the parents of children with polygenic determined defects, less pronounced ones -- in the parents of children with multiple congenital non-chromosomal defects and with Down's syndrome. The frequency of the pathological features studied was similar both in children with polygenically determined isolated defects and in their parents. In multiple congenital defects and in Down's syndrome the abnormalities of the localization of an axial triradius and of the flexor creases were found in children more frequently than in the parents. It is suggested that the above mentioned peculiarities of parental dermatoglyphics may be useful for the genetic counselling.

Dermatoglyphics in rheumatoid arthritis.

Patients with rheumatoid arthritis have been referred to Division of Human Genetics for counselling. Qualitative dermatoglyphics comprising of finger print pattern, interdigital pattern, hypothenar pattern and palmar crease were studied on 26 female and 11 male rheumatoid arthritis patients. Comparison between patient male and control male; and patient female and control female has been done. 'Chi' square test was performed. In male patients, with hands together, arches were increased, loops/ whorls were decreased. Partial Simian crease was significantly increased. In the right hand, patterns were increased in the 3rd interdigital area. On the other hand, in female patients there was a significant increase in whorls and decrease in loops on the first finger on both the hands, increase in arches on the 3rd finger; both arches and whorls on the 4th finger of left hand. Present study has emphasized that dermatoglyphics could be applied as a diagnostic tool to patients with rheumatoid arthritis.

[Dermatoglyphics in children with constitutional exogenous obesity].

The results of investigation of dermatoglyphics were analyzed in 544 children suffering from constitutional exogenous adiposity. The results of population-based studies of a regional medicogenetic counselling service (1240 persons) were taken as control data. Dermatoglyphic changes included papillary patterns intensified at the expense of loops and twists. An increase in the atd angle value, a-b count in boys, the presence of additional triradii, abnormal endings of the main palm lines, a reduced C line, the absence of the C triradius in patients with constitutional exogenous adiposity as well in their relatives of the 1st degree of kinship were revealed.

Regional differentiation of sole dermatoglyphs in rural population in Poland.

The study presents a comparison of the distribution of sole dermatoglyphs in the rural populations of different regions of Poland, namely, the Lublin region, the areas of Suwałki, Ostrołeka, and of the village of Giebło. A comparison of the occurrence frequency of dermatoglyphs in the population of the Lublin region and that of their occurrence in the populations of Suwałki, Ostrołeka and Giebło areas reveals statistically significant differences between particular patterns. The differences result from ethnic isolation and isolation of the communities caused by geographical barriers.

Analysis of the qualitative dermatoglyphics of the digito-palmar complex in patients with primary open angle glaucoma.

The primary open-angle glaucomas are a group of diseases that have in common characteristic morphological changes at the optic nerve head and retinal nerve fiber layer, progressive retinal ganglion cells death and characteristic visual field loss. The risk for primary open angle glaucoma rises continuously with the level of the intraocular pressure. The disease advances slowly and there are no symptoms. Primary open angle glaucoma is caused by abnormal aqueous humour outflow in the trabecular meshwork in the open angle. Etiopathogenesis of primary open angle glaucoma is unclear. The increased risk of glaucoma in relatives has long been recognized. Frequency for manifestation of the disease is 10-30% in family members. The discovery of the specific gene loci responsible for the manifestation of glaucoma has helped us to understand its mechanism of origin and definitely confirmed the hereditary nature of this disease. Digito-palmar dermatoglyphs were already used to determine hereditary base of many diseases and it was the reason for investigation of their qualitative patterns in patients with glaucoma (22 males and 23 females), their immediate relatives (19 males and 23 females) in comparison to a group of phenotypically healthy population (52 males and 56 females). The results pointed a connection with the dermatoglyphic traits of the digito-palmar complex between patients with glaucoma and their immediate relatives. There is a possible discrimination of patients and their immediate relatives from phenotypically healthy population, too.

[The study of dermatoglyphic parameters on 1000 Tibetans].

This paper reports 14 dermatoglyphic parameters of 1000 Tibetans sampled in Tibet. Relatedness between Tibetans and Hans is much closer than that between Tibetans and Minnesotians in the USA. Compared with 12 nationalities. The Tibetan showed smaller difference with the Hani and the Han and greater difference with the Uygur. Comparison among the Tibetans living in different regions suggests that the Tibetans in Tibet have less difference with the Tibetans in Pingwu Region of Sichuan Province and much difference with the Tibetans in Gannan Region of Gansu Province. This report indicates that dermatoglyphic Parameters should not be used indifferently in different ethnic groups or even in different geographic groups of the same nationality.

[Relationship between dermatoglyphic variability and finger length in genetic disorders: Down's syndrome].

Palmar and digital dermatoglyphics were compared in Down's syndrome patients with that in a control sample from a population. All dermatoglyphic changes characteristic of Down's syndrome were confirmed. The ridge counts along digital midlines were significantly lower in Down patients as compared to control data, especially, in little fingers, which corresponds to finger shortening in Down's syndrome. The findings agree with a suggestion that digital growth in man could be controlled by morphogenetic gradients which may be altered in genetic disorders.

[Quantitative dermatoglyphic markers in fra-X-syndrome].

Quantitative dermatoglyphic characters of fingers and palms of 61 male patients with fra-X-syndrome and 20 female heterozygote carriers were analysed and compared with the data from 84 male and 90 female normal individuals. Univariate and multivariate analysis of the data led to the following conclusions: 1. The fra-X-syndrome patients show higher ridge count and higher MLI value (increased transversality of the main lines), and lower a-b ridge counts than the controls. In addition to this, differences are observed also for the diversity and asymmetry measures. 2. Discriminant analysis as applied to the sexes separately, showed that 75% of males can be correctly classified in their group. However, the percent of correctly classified females is lower than the males; it is 70% (fra-X female) ad 64.4% (control female). 3. D2-matrix and the comparison of TFR C values support the hypothesis of X-chromosomal doses effect on the dermatoglyphics.

[Deviations in dermatoglyphic signs in juvenile hypertensives].

In 172 children and young adults aged 13-27 years dermatoglyphic deviations were investigated, as compared with the normal Prague population. The authors tested 116 hypertonic males, as compared with 130 male controls; 110 healthy women were compared with 56 suffering from hypertension. Using classical modern statistical tests, some significant deviations were found in the pathological groups. The authors detected a less frequent prevalence of ulnar loops and more frequent whirls on the fingers of hypertensive patients. The numbers of papillary lines on the fingers were higher, as compared with normal values. Higher "atd" values, although not significantly, were found a more frequent incidence of distal positions of the axial triradius. Deviations of some other signs on the palms such as the number of lines between triradii a and b, patterns in the interdigital spaces, on the hypothenar and thenar were less marked and there were moreover sex-conditioned differences. The observed changes suggest a marked participation of genetic factors in the aetiology of essential hypertension and they can be explained by laws of developmental mechanics of the papillary lines during embryogenesis. Dermatoglyphs, a non-invasive method, could serve as a screening indicator for the follow up of individuals in threatened families.
