Summary

This paper deals with some other population genetic aspects associated with the incidence of a type of primary congenital glaucoma that occurs very frequently in the Gypsy population of Slovakia. In addition to the decreased fertility of affected individuals of Gypsy origin being determined, the relative reproduction fitness and the selection coefficient against this disease were estimated. An increased number of kinship intermarriages in parents of the patients were recorded, namely in the Gypsy group (45.6%). The average inbreeding coefficient for the Gypsy group (F=0.0091) and the non-Gypsy group (F=0.0030) was calculated. Based on the high frequency of primary congenital glaucoma in a relatively small Gypsy subpopulation and on data about their origin, immigration, and settlements in the territory of Slovakia, the authors consider a special case of gene drift—the founder effect—to be the most plausible explanation of the given fact.
