Red cell glucose-6-phosphate dehydrogenase deficiency among Andhras.

Sixty-eight Andhra males and 45 Andhra females from Visakhapatnam town of Andhra Pradesh, India have been investigated for G-6-PD deficiency. The GdB- gene has a frequency of 4.41% among males. No G-6-PH deficient females were detected. The present data have been compared with the available tribal and non-tribal data from Andhra Pradesh. It is observed that the present sample, though non-tribal in nature, presents a relatively considerable frequency of the GdB- gene.
