Quantitative Difference in the New Allele Transferrin DGond Found in the Raj Gond Tribal Population of Andhra Pradesh (S.India)

Varieties of transferrin alleles have been found in different racial groups of man, and some of them have exhibited polymorphic frequencies, but no record is available to show quantitative differences among the alleles. A quantitative difference has been found in a new allele, Tf D_Gond, from the Raj Gond tribe whose electrophoretic mobility occupies a position between Tf D₁ and Tf D_Chi. Densitometer scanning of the gels indicating the proportion of Tf D_Gond to the normal allele Tf C is approximately 2:3. A pedigree study was done to confirm the genetically controlled nature of the allele Tf D_Gond.
