Transferrin (TF) C subtypes were studied in Swedish Lapps (Saami) and in Swedes from northern, central and southern Sweden, and the allele frequencies were compared with those in other European populations. The Swedish Lapps were found to have the lowest frequency of the TFC3 allele (1-2%) so far observed in Europe. Most European populations have TFC3 allele frequencies between 5 and 7%. Finns differ by having high TFC3 frequencies (13-14%). The relatively high TFC3 frequencies found in northeastern Sweden (13%) and in central Sweden (9%) are most likely due to eastern influence. Unlike other genetic markers of eastern influence (e.g. TFDCHI), which are of Asiatic Mongoloid origin, TFC3 appears to originate from Finno-Ugric populations.
