摘要: A polymorphism in the coding region of catechol-O-methyltransferase gene (COMT) was previously reported to be associated with obsessive-compulsive disorder (OCD), particularly male probands. We attempted replicate previous finding using a family-based genetic design haplotype relative risk (HRR) and transmission disequilibrium (TDT) analyses. Fifty-six OCD probands their parents were genotyped for COMT locus established methods. Analysis allele genotype frequencies between proband genotypes control (parental nontransmitted) failed gender divergence, gave no evidence overall association, nor linkage detected by TDT. However, further analysis mildly significant association low-activity female (P = 0.049), but not These findings indicate that may etiologically relevant gender-specific manner opposite shown studies. © 2001 Wiley-Liss, Inc.
