The objective of the present work was to study dermatoglyphic signs in suicidents (n=50) and in the subjects who were either killed or died as a result of an accident. It was shown that the correlation between selected dermatoglyphic signs and predisposition to suicide is either insignificant or moderately significant. The specific features of suicidal predisposition can be traced down to dermatoglyphics of all the friction ridged skin areas (fingers, palms, toes, and soles of the feet). Suicidal residents of the northwestern regions of Russia have been found to possess specific dermatoglyphic features. The effectiveness of the mathematical models of suicidal predisposition developed based on the 20 most informative dermatoglyphic characteristics amounts to 88%.
