Dermatoglyphics: a diagnostic aid?

چکیده

With the demonstration of a strong genetic component in ridge counts by Sarah Holt (eg, Holt, 1961), which came as the culmination of a large number of early exploratory papers on the inheritance of dermatoglyphic traits (summarized in Cummins and Midlo, 1961), the relationship of finger and palm prints with genetic disease was an obvious topic for exploration. During the last decade a number of claims have been made for their association with various diseases, eg, leukaemia (Verbov, 1970), rubella embryopathy (Achs, Harper, and Siegal, 1966), schizophrenia (Mellor, 1968). In particular their relationship to disorders of the sex chromosomes and some autosomes has been well established (Penrose, 1967) and methods of using these as aids in diagnosis devised (Walker, 1957). Claims for association with other non-chromosomal types of familial disorder however have tended to proliferate on the basis of simple comparison of dermatoglyphic characters or their frequencies in patients with the disease and in reputedly normal samples. The fundamental assumption is that since many genes take part in the formation of dermatoglyphic characters, it is possible that genes which predispose to familial disease may, by pleiotropy, also influence the ridge patterns so that particular constellations of dermatoglyphic features may be characteristic of a particular disease. Yet there has been no attempt to carry the analysis further, and to enquire whether possession of the

Alopecia Areata and Dermatoglyphics

Objective: To study of relationship between alopecia areata and finger print dermatoglyphic types in 100 patients with alopecia areata and in 100 controls. Methods: A case control analytical study was done on fingerprints of patients with alopecia areata. The control cases were older than 50 years old without any history of alopecia areata. Dermatoglyphical trials of total fingers were al...

Embryologic development of epidermal ridges and their configurations.

The configurations of epidermal ridges that comprise dermatoglyphic traits are, in many respects, a history of the developmental period during which the ridges form. In 1892 Sir Francis Galton [l] demonstrated that epidermal ridge configurations did not change throughout postnatal life. The fact that ridge configurations were not affected by environment or by age has been an important framework...

Dermatoglyphics in diabetes: a prospective diagnostic aid and early preventive tool

50 PRACTICAL DIABETES VOL. 32 NO. 2 COPYRIGHT © 2015 JOHN WILEY & SONS Introduction Dermatoglyphics are ridged patterns on the palmar and plantar surfaces of humans (fingerprints, palm prints and foot prints), which develop approximately between the 13th and 18th weeks of gestation. They manifest complex genetic backgrounds that are currently not fully explained, but polygenic multifactorial in...
