Population study in Assam: ABO blood groups, haemoglobin E and G-6-PD deficiency.

Abstract: An attempt has been made to give a comprehensive picture of occurrence of ABO blood groups, haemoglobin E and G-6-PD deficiency among certain representative populations of the two major racial groups--Mongoloids and Caucasoids--of Assam, India. The qualitative pattern of distribution of ABO gene frequencies shows a clear demarcation between these two major groups. The same is true in respect of HbE gene, too. The Mongoloids present high frequencies of this gene, while among the Caucasoids its frequency is comparatively much lower. With regard to G-6-PD deficiency the distinction between the two groups is not so clear cut, yet some Mongoloid populations show relatively higher incidence of the trait in comparison to that in the Caucasoid populations.
