Dermatoglyphic analysis of autistic Basque children

Abstract

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.

Dermatoglyphic characteristics of digito-palmar complex in autistic boys in Serbia

“…In addition to this research we certainly have to add the results that were obtained by Arrieta et al 19 , which also confirmed that autistic children have a lower TRC and a wider atd angle, so, it is concluded that the obtained results do not contradict the hypothesis that genetic factors might be significant in etiology of unknown origin autism.…”

Mild Dermatoglyphic Deviations in Adolescents with Autism Spectrum Disorders and Average Intellectual Abilities as Compared to Typically Developing Boys

“…Not all studies, however, agree on this finding [ 34 ]. Arrieta and colleagues [ 35 ] found larger atd-angles in girls with ASD than in boys. A few descriptions of dermatoglyphic variables in people with ASD in Eastern European countries (Croatia, Romania, and Serbia) have recently become available.…”

“…[3][4][5][6][7][8][9][10][11][12][13][14][15]. Dermatoglyphics patterns are reported to be markers for certain genetic disorders like Down's syndrome [16,17], autism, [18] and skeletal malformations such as polydactyly [3]. It is also useful in psychiatry [19] and in the diagnosis of Schizophrenia and other medical conditions such as cardiovascular diseases, diabetes mellitus type II, epilepsy, hypertension [20][21][22][23], Kanner's syndrome [22,24], hypoparathyroidism, [3,25,26], Klinefelter's syndrome [27] as well as in dentistry [28][29][30][31][32].…”
