[Genetic markers and congenital cataract].

In this work an attempt has been made to analyze the relationship between genetic markers and the occurrence of congenital cataract in children. The study included 32 families with 66 children in whom various clinical forms of congenital cataract had been diagnosed. In all examined patients, genetic markers such as ABO, MN, Rh systems, Gm1 factor, acid phosphatase (ACP1), esterase D and haptoglobin group were determined. The results were compared with the control population. It was found that the frequency of occurrence of heterozygote phenotype Hp 2-1 is higher in families with congenital cataract with simultaneous decrease of the frequency of occurrence of homozygote Hp 2-2. The obtained data were compared with those of other authors.
