ГЕНЕТИЧЕСКАЯ ЭПИДЕМИОЛОГИЯ НАСЛЕДСТВЕННОЙ ПРЕДРАСПОЛОЖЕННОСТИ К КЕРАТОКОНУСУ

The survey of the literature devoted to genetic epidemiology of keratoconus and also principles of genetic markers search showed predisposition to this disease suitable for screening test in the course of genetic certification of the population. It was revealed that hereditary predisposition to keratokonus was caused by gene mutations, encoding cellular cycle and metabolism of the keratocytes regulating the activity of tissue proteolytic enzymes, and also mechanisms of natural detoxification. Genes associated with keratoconus are characterized by allelic variation and multiple mutations taking different degrees of association with clinically apparent diseases. It was discovered that genotypes of people from different geographic regions can differ in terms of signs and markers showing predisposition to the disease.
