Erythrocytic glucose-6-phosphate dehydrogenase deficiency in the Bania community of Punjab.

Five hundred members belonging to the Bania community of Punjab were screened for erythrocytic glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. The incidence of enzyme deficiency in males was 2.84 per cent and in females 2.75 per cent, with an overall incidence of 2.80 per cent. No correlation between age and G-6-PD deficiency was found. The mean values for haemoglobin and haematocrit did not differ significantly in the normal and deficient subjects. Study of the deficiency pattern amongst family members of the enzyme deficient subjects confirmed the X-linked inheritance of G-6-PD deficiency.
