Serum complement (C3, BF, C4) types in Swedish Saamis.

Human heredity - 1 Jan 2000

Beckman G, Beckman L, Sikström C

Abstract excerpt

Serum complement (C3, BF, C4) types were examined in Swedish Saamis (Lapps). In agreement with previous studies, a very low frequency of the C3*F allele (0.033) was found. Compared to Swedes and other Caucasian populations, Swedish Saamis showed a significantly increased frequency of the BFS, C4A...
