Genetics and dermatology.

An attempt has been made to show and discuss today's problems of genodermatology, mentioning the important groups of the heterogenous diseases and enzyme defects which are coupled with the skin diseases. Moreover, the chromosomes breakage syndromes are reviewed. To a great extent, these problems are of theoretical interest, but the genetic counselling is on the increase and already plays an important part in the daily routine of the large hospitals.
