Inherited Metabolic Disease Phenylketonuria and Deficiency of G6pd Enzyme In A Family Study

The family with identified inherited metabolic disease of phenylketonuria lives in Masally administrative area. Masally area itself is located in South-East of Azerbaijan Republic on the slopes of Talysh mountains in subtropical zone. Members of proband’s family possess deficiency of glucose-6- phosphatedehydrogenase. Phenylketonuria gene has an identified R261G (G-A) mutation. The study of erythrocyte enzyme preparation for family members have shown low electophoretic mobility for G6PD which was unknown in the world studies. Based on the Michaelis-Menten constant (Km) applied to G6P, substrate values have manifested high biochemical polymorphism.
