Haplotype-Based Linkage of Tryptophan Hydroxylase 2 to Suicide Attempt, Major Depression, and Cerebrospinal Fluid 5-Hydroxyindoleacetic Acid in 4 Populations

Abstract

Haplotype linkage of TPH2 to suicide attempt and major depression and to a mediating phenotype, cerebrospinal fluid 5-hydroxyindoleacetic acid, provides preliminary evidence of a functional locus potentially within a haplotype block at least 52 kb in size.
