Dermatoglyphics in Down's syndrome.

Dermatoglyphic data were obtained from 235 cytogenetically confirmed patients of Down's syndrome. The data were correlated and compared with 230 controls. Printing and transparent adhesive tape photography methods were used to get the dermatoglyphic prints. Patients' total finger ridge counts and 'atd' angles differed significantly from that of the controls. Mostly ulnar loop pattern was observed in the patients. Abnormal dermatoglyphic features such as, simian crease, Sydney line and patterns in the hypothenar and interdigital areas have occurred more frequently in the patients. Dermatoglyphics and the analyses carried out have proved that they are invaluable in their clinical value, in selecting patients of Down's syndrome for cytogenetic analysis.

Analysis of the quantitative dermatoglyphics of the digito-palmar complex in patients with multiple sclerosis.

Recent studies on the etiopathogenesis of multiple sclerosis (MS) all point out that there is a polygenetical predisposition for this illness. The so called "MS Trait" determines the reactivity of the immunological system upon ecological factors. The development of the glyphological science and the study of the characteristics of the digito-palmar dermatoglyphic complex (for which it was established that they are polygenetically determined characteristics) all enable a better insight into the genetic development during early embriogenesis. The aim of this study was to estimate certain differences in the dermatoglyphics of digito-palmar complexes between the group with multiple sclerosis and the comparable, phenotypically healthy groups of both sexes. This study is based on the analysis of 18 quantitative characteristics of the digito-palmar complex in 125 patients with multiple sclerosis (41 males and 84 females) in comparison to a group of 400 phenotypically healthy patients (200 males and 200 females). The conducted analysis pointed towards a statistically significant decrease of the number of digital and palmar ridges, as well as with lower values of atd angles in a group of MS patients of both sexes. The main discriminators were the characteristic palmar dermatoglyphics with the possibility that the discriminate analysis classifies over 80% of the examinees which exceeds the statistical significance. The results of this study suggest a possible discrimination of patients with MS and the phenotypically health population through the analysis of the dermatoglyphic status, and therefore the possibility that multiple sclerosis is genetically predisposed disease.

Genetic and environmental influence on the asymmetry of dermatoglyphic traits.

Fluctuating asymmetry (FA) is defined as random deviations from bilateral symmetry of the body. Thus, its magnitude is often used to evaluate developmental homeostasis. In this study we evaluate the following hypotheses: 1) FA of dermatoglyphic traits has a significant genetic component; 2) prenatal maternal environment (PME) has a significant effect on the FA of dermatoglyphic traits in developmentally healthy individuals; and 3) genetic or environmental factors affect FA on organismal or systemic levels. Therefore, their effect is better seen in composite scores of FA rather than in FA indices for single traits. We analyzed 15 dermatoglyphic traits from 140 pairs of monozygous twins, 120 pairs of dizygous twins, and 106 pairs of mothers and daughters. All individuals were developmentally healthy. The influence of genetic and environmental factors on FA was evaluated by analysis of variance and regression analysis. For a majority of the traits in our study, FA showed significant but weak heritabilities, with values falling within the 0.20-0.35 range. None of the traits taken separately demonstrated the effect of PME on FA to be significantly greater than zero. The composite score of FA tended to have greater heritability values than individual traits. One of them, obtained in principal components analysis, showed a significant PME effect, supporting the hypothesis that FA is a systemic property.

Blood groups, immunoglobulin allotypes and dermatoglyphic features of patients with amyotrophic lateral sclerosis and parkinsonism-dementia of Guam.

Blood group frequencies, immunoglobulin allotypes, and dermatoglyphic patterns were determined on patients with amyotrophic lateral sclerosis (ALS) and parkinsonism-dementia (PD), two chronic, degenerative, neurologic disorders of unknown cause found commonly among the Chamorros of the Mariana Islands, in an attempt to identify a specific genetic or phenetic marker associated with either disorder. With the exception of the Kidd system, no significant differences were found in blood group frequencies nor in immunoglobulin allotypes between ALS patients, PD patients, and unaffected controls. The dermatoglyphic analysis demonstrated that ALS patients had higher frequencies of palmar patterns and accessory triradii in the IV interdigital area, and PD patients had significantly higher frequencies of complete simian creases and of palmar patterns in the thenar/I interdigital area than unaffected controls. The frequencies of the remaining dermatoglyphic traits showed no significant differences. We conclude that none of the marker systems tested show a particular pattern of association in patients and controls or a genetic predisposition to either disorder, and that early identification of at-risk individuals remains elusive.

Dermatoglyphic indices of males with the fragile X syndrome and of the female heterozygotes.

Indices for males with the fragile X [fra(X)] syndrome and for the female heterozygotes have been established. The indices were based on the increased frequencies of whorls and radial loops on the third digits of affected males and heterozygous females, increased frequency of arches on the third digits of the affected males, and an excess of low ab ridge counts and abnormal palmar creases, particularly the Sydney crease, in both sexes. The indices were calculated using the logN odds ratio based on the frequencies of the above dermatoglyphics and palmar creases in 47 males with the syndrome compared to 497 male controls and 36 heterozygous females compared to 493 female controls. The indices had similar distributions in males and females. Seventy per cent of males with the syndrome and 67% of female heterozygotes had an index greater than or equal to +0.5. Thirty-one per cent of female heterozygotes who had both the dermatoglyphic index calculated and their chromosomes examined under appropriate conditions for the fra(X) site had an index less than +0.5 and had less than 2% fragile sites (most had none). However when the two tests were considered together, only 4/35 (11%) of the heterozygotes would not have been identified using the two criteria. The data suggest that the dermatoglyphic index is a helpful adjunct test with chromosome analysis for the identification of fra(X) heterozygotes.

Dermatoglyphic traits as possible markers of developmental processes in humans.

Here we provide data on the relationship in variability between common anthropometric characters (stature, interocular diameter, mesosternal chest circumference, bi-trochanteric diameter, and palm length) and dermatoglyphic traits in groups of young healthy individuals. Our working hypothesis was that quantitative variables of fluctuating asymmetry, diversity, and variability involving dermatoglyphic traits, will be higher in more homozygous groups than in heterozygous ones. It was found that individuals who were in the center (average +/- 0.67 SD) of the morphological trait distribution (and therefore perhaps more heterozygous at loci determining the aforementioned morphological traits), have reduced fluctuating asymmetry in their ridge counts (RC). These heterozygous individuals tended to have lower values of the RC-diversity-indices and the Shanon information-measures of discrete digital patterns. On the basis of the present results and a large body of literature data, the use of dermatoglyphic traits as "markers" of developmental processes are discussed.

Dermatoglyphic analysis of autistic basque children.

We have analyzed the digital and palmar dermatoglyphics in a sample of autistic children from the Basque Country. The results have been compared with those from a control sample having the same characteristics relative to the ethnic region. We found significant differences between the digital dermatoglyphics of autistic boys and control boys. Autistic children have a higher frequency of transitional radial loops and a lower frequency of dicentric whorls; also the total finger ridge count (TFRC) and radial count are lower in autistic individuals. There were no significant differences in the girls. In palmar dermatoglyphics, autistic girls have a lower frequency of radial loops in the hypothenar area, and the value of the "atd" angle is higher than in control girls. These differences were significant. The a-b interdigital ridge count is significantly lower in autistic boys. Autistic children of both sexes have a higher frequency of aberrant palmar creases. The results obtained in the present study do not contradict the hypothesis that genetic factors may be important in autism of unknown cause.

Dermatoglyphics of schizophrenics, patients with Down's syndrome and mentally retarded males as compared with Australian Europeans using multivariate statistics.

Dermatoglyphics of schizophrenics, patients with Down's syndrome and mentally retarded males were compared with those of normal Australian Europeans. A computer programme of multivariate analysis of fifteen dermatoglyphic features was utilized. This analysis produces two significant variates of each of the populations plotted in two-dimensional space. The distance, measured in arbitrary units, between any two populations was studied for its significance. It was noticed that the patients with Down's syndrome separated significantly from the rest of the groups. The importance of multivariate analysis in the study of dermatoglyphics in comparing two or more populations is discussed.

Dermatoglyphic characters and physique: a correlation study.

The association of anthropometrics, particularly hand measurements, with dermatoglyphic characters is quantified. Children with square hands exhibit higher main line indices, a-b ridge counts, and more open atd angles. Adults with broader hands have more arches. Taller individuals with larger hands present higher a-b ridge counts and leaner subjects with long narrow hands, closer atd angles. The correlation of physique and dermatoglyphics is small but if verified, suggests that at early fetal stages, factors responsible for the establishment of dermatoglyphic patterns interact with genetic determinants of adult shape that are already active.

A comparison of dermatoglyphic methodologies in population studies.

Use of dermatoglyphics in population studies has been marked by a great deal of methodological variation among investigators. We compare various dermatoglyphic approaches using data derived from four groups in the Kumaon region of India. Dermatoglyphic data included ridge-counts and other quantitative variables, and the classification systems of Cummins and Midlo and Penrose and Loesch. Results were evaluated against anthropometric and serological relationships. No clearly superior approach emerges, although it is generally true that palmar variables exhibit more intergroup heterogeneity than digital variables and produce more reasonable results than the other approaches. The conventional method of treating ridge-counts, that of choosing the larger of the two counts, was the most unsatisfactory of the quantitative approaches, leading to the recommendation that both radial and ulnar counts be retained. We conclude that environmental variation may contribute substantially to intergroup variation.

Digital dermatoglyphics of Bulgarians from northeast Bulgaria.

Digital dermatoglyphics were collected from 1,065 male and 1,065 female Bulgarians from northeast Bulgaria. None of the subjects had a diagnosed or suspected genetic or chronic disease of any kind. The fingerprints were classified by the 18-type system of Monique de Lestrange, modified to provide rapid and easy comparison with simpler classification systems. All the standard finger pattern indices were calculated. Certain modifications were introduced into the delta indices, it being borne in mind that each tented arch possesses a triradius and each complex (three-centered, accidental) whorl contains three triradii. A deltadiagram was constructed and its configuration was compared with those of some other populations. In addition, a new radioulnar index was proposed, representing a ratio between all the radial and all the ulnar patterns. The total, absolute, ulnar and radial finger ridge counts were calculated and their sample distributions were investigated. The dermatoglyphic features were evaluated and presented for each sex and each hand separately in order to investigate both the sex and bilateral differences. The set of data presented in this paper is a component of the physical anthropology of the general Bulgarian population. At the same time these data can be used as controls when analyzing the dermatoglyphic findings in Bulgarian patients with genetic diseases or congenital malformations.

Anthropometric multivariate structure and dermatoglyphic peculiarities in biochemically and morphologically different heterozygous groups.

Multivariate analysis of the relationship between degree of heterozygosity at four blood group loci and the morphological variability in a human population was carried out. Additionally, the possibility that dermatoglyphic patterns correlate with biochemical and anthropometric variables was also investigated. A strong and significant increase in the frequency of morphologically multimodal individuals was observed, which paralleled the heterozygosity level. Discriminant analysis, by quantitative characters, of the closest pair of biochemically different samples yielded a satisfactory discrimination. Multiple correlations of each variable with all the others (18 traits), the communality of characters, the index of integration, and the Mahalanobis distances of the factor scores for each individual (all extracted from principal component analysis) were all indicative of the different multivariate structures of homo- and heterozygous individuals and thus supported the hypothesis that heterozygotes tend to cluster near the center of the joint multivariate distribution. The dermatoglyphic patterns showed a certain relationship with the morphological makeup of individuals. Correlations between biochemical heterozygosity at blood group loci and patterns of digital dermatoglyphics were rather irregular.

Dermatoglyphic abnormalities in the fetal alcohol syndrome.

Dermatoglyphics of 19 male and 23 female patients with fetal alcohol syndrome were compared with those of matched controls. Both male and female patients differed in several of the dermatoglyphic characteristics from their sex-matched controls. The abnormalities of dermatoglyphics reported here constitute a valuable marker trait of the teratogenic effect of the alcohol on fetal development and provide additional diagnostic signs for the fetal alcohol syndrome.

A comparative dermatoglyphic study of autistic, retarded, and normal children.

Dermatoglyphic comparisons were made among 32 autistic children aged from 4-10 to 18-11; sex-, age-, and IQ-matched retarded children; and sex- and age-matched normal children. Significant differences were found between the autistic and normal children for distribution of dermal patterns and ridge line disruption, but no significant differences were found for the total mean ridge counts or mean ridge count rankings. Apart from the right hand of the autistic children, there were no unusual scores for digital dispersion ratios. Autistic and retarded children differed only in their distribution of dermal patterns, with the autistic children apparently intermediate between retarded and normal groups. These results indicate that conclusions of unique congenital disturbance in the etiology of autism inferred from different dermatoglyphics may be premature, and that dermatoglyphics may be ineffective in delineating autistic children from other atypical populations.

Dermatoglyphic patterns in children with chronic constipation.

Analysis of the fine ridge configurations on the digits of the palms and soles (dermatoglyphics) may sometimes help in the diagnoses of certain medical disorders. Dermatoglyphic patterns have been reported to be associated with congenital anomalies, such as congenital heart disease, duodenal ulcer, abdominal pain, and constipation. The palmar dermatoglyphic patterns of 77 children with constipation (39 functional and 38 organic constipation) were recorded. The control group consisted of 84 children with inguinal hernia. Those patients with at least one arch identified on any digit of either hand were termed arch positive. There was no significant correlation between arch positivity and constipation (functional or organic), or inguinal hernia (chi square, P = 0.9211). Therefore, the presence of palmar arches cannot be used as a screening device for children with chronic constipation, especially of organic etiology.

Congenital absence of dermatoglyphs.

Congenital absence or unusual patterns of human dermatoglyphs (fingerprints) occur in several syndromes that are rare and poorly understood. The abnormalities of dermatoglyphs fall into four categories: complete absence, ridge hypoplasia, ridge dissociation, and ridges-off-the-end. Complete congenital absence of ridges is an exceedingly rare syndrome that consists of neonatal blisters and milia, adult traumatic blistering and fissuring, absence of sweating, contracture of digits, and absence of dermatoglyphs on the hands and feet. The syndrome is inherited in an autosomal dominant pattern, and only two kindreds have been described in the literature. We describe a newly identified patient and kindred with findings similar to the previously reported cases and review the clinical and histopathologic findings of this syndrome.

Palmar dermatoglyphics in congenital hand anomalies.

A palmar dermatoglyphic study of 392 hands of patients with congenital hand anomalies was performed to evaluate the number of digital triradii, the position of an axial triradius, the incidence of hypothenar patterns, the pattern intensity, and the main line index. Remarkable variations, which are rare in normal hands, were frequently observed. The results deviated from the normal range in cases of ectrodactyly and syndactyly, but were within the normal range in cases of polydactyly. The dermatoglyphics associated with each type of hand anomaly was characteristic and discriminative. Dermatoglyphics was also helpful in evaluating the function of the hand, and in estimating the time of the damage to the hand in embryogenesis.
