Population studies in northern Sweden. XVI. GC subtypes.
The frequencies of group-specific component (GC) subtypes were studied in a population of 4,053 conscripts and blood donors from the counties of Västerbotten and Norrbotten in northern Sweden. The individuals were distributed according to place of birth into 23 subpopulations. A significant heterogeneity between the 23 regions was observed for the GC*1F, GC*1S and GC*2 genes, and clines were found for all genes. The frequency of the GC*1F gene was increasing in the northern direction, and the frequencies of the GS*1S and GC*2 genes were increasing in the southern direction. The geographical pattern of the GC*1F gene frequency could be explained in terms of Lappish influence.
