title: C3 polymorphism in North India.
abstract: C3 polymorphism has been studied in 428 individuals from four populations of North India. The frequency of the C3F gene ranges between 0.086 to 0.139. The C3F gene frequency is comparatively higher in the studied samples as compared to other Indian populations, but lower than in most European and West Asian populations.
