title: A new glucose-6-phosphate dehydrogenase variant (G-6-PD Kalyan) found in a Koli family.
abstract: A new Indian variant of erythrocytic glucose-6-phosphate dehydrogenase (G-6-PD) has been detected in a Koli male subject during population genetic studies. The enzyme variant is characterized by mild enzyme deficiency, slow electrophoretic mobility, low Km for G-6-P, increased utilization of substrate analogues, heat instability and a normal pH optimum curve. From these results this was considered to be a new variant and was designated G-6-PD Kalyan. The family history and routine hematological studies did not reveal any evidence that the G-6-PD Kalyan is associated with any hematological abnormalities or clinical symptoms.
