[Dermatoglyphic changes in some human hereditary disorders: syndactyly].
The dermatoglyphic hand prints from 19 patients with different types of syndactyly were analysed. It was shown that some digital triradii and palmar lines were missing and replaced by only one triradius with common radiants and one main palmar line in patients with syndactyly. With fingers fused incompletely so called zygodactylous triradius and the main Z line may appear, instead of or alongside with them. It is proposed that the position of local cell death in the interdigital spaces is determined by positional information which is expressed in the system of polar coordinates.
