Red cell glucose-6-phosphate dehydrogenase deficiency and haemoglobin variants among ten endogamous groups of Maharashtra and West Bengal

Abstract

Over 900 individuals from ten endogamous groups in the Indian states of Maharashtra and West Bengal were studied for G-6-PD deficiency and haemoglobin variants. The incidence of G-6-PD varied from nil to 17.3%, while that of Hb-S varied from nil to 22.3%. In general, the tribal populations of Maharashtra are characterized by the presence of a high incidence of both Hb-S and G-6-PD deficiency. The caste Hindus showed an absence of Hb-S and rather low G-6-PD deficiency. Immigrant Parsis possessed the highest incidence of G-6-PD deficiency (17.3%).
