Transferrin, haptoglobin and group-specific component types in tribal populations of Andhra Pradesh

Five tribal populations, Koya Dora, Raj Gond, Naikpod, Pardhan, and Lambadi from Andhra Pradesh were examined for Tf, Hp, Gc, ceruloplasmin and albumin types. Koya Doras were sampled at five localities to study intra-tribal variation. Tf DChi, a mongoloid genetic marker, was found in high frequencies among Koya Doras (0.029) and Naikpods (0.033) whereas if was absent among Pardhans and showed a very low frequency in Lambadis. A new slow transferrin allele, Tf DGond, is reported from Raj Gonds and is found in polymorphic frequency (0.01). The Hp1 gene frequency ranged from 0.056 to 0.159, and Gc2 ranged from 0.165 to 0.397. No variation was observed with respect to ceruloplasmin. One new albumin variant was found in a single individual of the Koya Dora tribe. The intra-tribal variation in gene frequencies among Koya Doras equalled that found between different tribal populations.
