Gm and Km frequencies in West Germans: usefulness of typing Gm(1,2,3,10,21) and Km(1,3) in paternity cases.

The immunoglobulin allotypes G1m(1,2,3) and G3m(10,21) were typed in 2855 unrelated West German adult individuals. 1455 individuals were typed for the factors Km(1,3). Phenotype and haplotype frequencies are reported. The usefulness of this routine typing programme in paternity tests is demonstrated in three case reports.
