Abstract

Dermatoglyphs are epidermal ridges on the volar surfaces of fingers, toes, palms and soles.Their development begins between 6th and 7th gestational week, so that critical stage of ridge differentiation occurs in the first trimester, coinciding with critical phase of embryonal development. The inheritance of epidermal ridge patterns is polygenic, often markedly affected by some environmental factors causing them to be reffered as multifactorial traits. Genetic determination, time of occurrence, stability and high individuality enable dermatoglyphic analysis to give an insight in critical stage of embryogenesis. Unusual dermatoglyphic variables are found to be significant markers in many numerical and structural chromosomal aberrations .Many investigations have proved epidermal ridges configuration analysis as a powerful additional screening method in identification of congenital anomalies, detection and prevention of different genetically caused disturbances.
