Description

G6PD Kerala (Azevedo et al., 1968) and G6PD Kalyan (Ishwad and Naik, 1984), 2 variants discovered in India, were thought to be distinct on the basis of their biochemical properties. Ahluwalia et al. (1992) demonstrated that the molecular defect is identical. Both have a glu317-to-lys mutation which causes a loss of 2 negative charges; this is in keeping with the very slow electrophoretic mobility of G6PD Kerala-Kalyan. Both are accompanied by only mild enzyme deficiency. In both, the mutation is a C-to-T transition in the CpG dinucleotide. The mutations were found in 2 populations that are entirely distinct linguistically and culturally with no known historical links. However, in light of the traditional occupation of the Koli tribal group inhabiting the Kalyan district of Bombay, namely, marine fishing, victims of bad weather may have found their way to distant places where they were forced to live for some period, thus creating the possibility of gene flow.
