Transferrin subtypes in six Indian population samples.

Transferrin subtypings have been performed on three population samples originating from Himachal Pradesh, North India (Pangwala, Gaddi-Bharmour valley, Gaddi-Kangra district) and on three samples from Andhra Pradesh, South India (Koya, Konda Kammara, Lambadi). Among these six populations, marked differences in the distribution of Tf phenotype and allele frequencies are present. All Indian samples differ clearly from the hitherto reported TfC1 and TfC2 allele frequencies. In one of our Indian samples, the Pangwala, the most likely existence of a new Tf subtype variant (Tf Pangwala) could be demonstrated.
