Mapping disease risk

An Indian database has been created by profiling the population on the basis of changes in genes with disease linkages. THE first results from the project of the Indian Genome Variation Consortium (IGVC) have clearly demonstrated (Frontline, June 6) that even as the Indian population exhibits a genetic diversity unmatched anywhere in the world, there are within it pockets of homogeneous ethnic groups that have remained relatively genetically unadmixed. (The IGVC's multi-institutional project was set up to evolve a disease-linked genetic map of India.)
