A genome-wide linkage study of schizophrenia in a large sample from Tamil Nadu, India

Funded Activity Summary

A Study of Schizophrenia in Tamil Nadu, India. The cause of schizophrenia is unknown, but there is good evidence that genes play a role. Geneticists do not fully understand how the disease is inherited, but it is very complex, and several interacting genes as well as environmental factors are probably involved. We have been recruiting families with at least two siblings with schizophrenia from a number of communities-casts in Tamil Nadu. We plan to recruit a total of 400 affected sibling families, together with 400 trio families (both parents, plus their affected child). A genome-wide scan of the genetic code in all individuals will be conducted to identify chromosomal regions linked to schizophrenia. This is the first necessary step toward identifying schizophrenia susceptibility genes. If one or more genes are discovered, this will greatly improve our understanding of this disease. It will also stimulate the search for similar genes in other samples world-wide, including Australia where schizophrenia costs $2.5 billion annually in terms of treatment and loss of employment. With such a discovery, it may be possible to find better treatments that correct the basic cause of the illness and identify factors that protect against the illness.
