The direct estimation of heritability from genome-wide common variant data as implemented in the program Genome-wide Complex Trait Analysis (GCTA) has provided a means to quantify attributable all interrogated variants. We have quantified variance liability disease explained by SNPs for two phenotypically-related neurobehavioral disorders, obsessive-compulsive disorder (OCD) and Tourette Syndrome (TS), using GCTA. Our analysis yielded point estimate 0.58 (se = 0.09, p 5.64e-12) TS, 0.37...
