Transferrin subtypes in four Northwest Indian tribal populations and some remarks on the anthropological value of this new polymorphism.

Serum samples from four tribal Populations--Chaudhuri, Kotwalia, Vasava, Gamit-living in Gujarat (Northwest India) were tested for transferrin subtypes. The results are compared with those reported for other Indian populations. Reviewing all the hitherto published Tf subtype data some interesting racial differences in the distribution of gene frequencies emerge. A possible geographical distribution pattern of the variants is explored.
