Allele frequencies of human complement factor I in a sample from Iwate, northern Japan, with the description of geographical cline.

Human heredity - 1 Jan 1991

Nakamura S, Omoto K, Sawaguchi A

Abstract excerpt

Serum samples from 270 healthy blood donors of Iwate prefecture, northern Japan, were examined for polymorphism of factor I (IF) by using polyacrylamide gel isoelectric focusing followed by semidry horizontal electroblotting with enzyme immunoassay. In 270 individuals four different patterns were observed, and these were controlled by two common alleles, IF*A and IF*B, and one rare allele, IF*A2. Allele...
