A putative association of schizophrenia with a Msc I restriction fragment length polymorphism at the dopamine D3 receptor gene locus (DRD3) was tested among Indian families, using haplotype relative risk analysis and the transmission disequilibrium test (n=66 families and 58 sets of transmissions, respectively). A significant association either with homozygosity or with allele 1 at the biallelic polymporphism could not be detected.
