Gender-specific association of TSNAX/DISC1 locus for schizophrenia and bipolar affective disorder in South Indian population.

Genetic association studies have implicated the TSNAX/DISC1 (disrupted in schizophrenia 1) in schizophrenia (SCZ), bipolar affective disorder (BPAD) and major depression. This study was performed to assess the possible involvement of TSNAX/DISC1 locus in the aetiology of BPAD and SCZ in the Southern Indian population. We genotyped seven single nucleotide polymorphism (SNPs) from TSNAX/DISC1 region in 1252 individuals (419 BPAD patients, 408 SCZ patients and 425 controls).
