To the Editor:

McMahon and colleagues1 recently reported a genome-wide significant association of rs2251219 on chromosome 3p21.1 with mood disorders in a combined sample of individuals with bipolar affective disorder (BP, also known as 'manic depression') and individuals with major depressive disorder (MDD). They meta-analyzed published data from four genome-wide association studies (GWAS) of BP2,3,4,5 and three published GWAS of MDD6,7, plus an unpublished German BP sample. Their analysis supports the suggestive association with bipolar disorder in this region previously reported by Scott et al.3 in a GWAS meta-analysis of three of the same BP samples (National Institute of Mental Health-BP4, Wellcome Trust Case Control Consortium2 and the GlaxoSmithKline-BP samples3), but we report here alternative analyses and new data inconsistent with an association in this region with MDD. Thus, rs2251219 appears to be a susceptibility locus for BP alone, and the data do not support a general association of this SNP with mood disorders.
