[Genetic dimorphism in beta-aminoisobutyric acid excretion in patients with atherosclerosis of the coronary artery and in groups at risk for atherosclerosis in the Lithuanian population].

Frequency of genetic variants of excretion of beta-aminoisobutyric acid (BAIB) in the urea was examined in patients suffering from atherosclerosis of coronary arteries and in risk group for atherosclerosis: children frequently suffering from respiratory viral infection, children with insulin-dependent diabetes mellitus (IDDM) and in adults suffering from IDDM and non-insulin-dependent diabetes mellitus. With the aim to determine whether excretion of BAIB could be related with CMV persistence of with proteolytic activity of blood serum the IgG class antibodies against CMV and level of alpha 1-proteinase inhibitor (alpha 1-PI) in blood serum was tested also. Frequency of high excretors of BAIB was found significantly more often (P < 0.
