heritability and 25% (h2 = 0.08; se = 0.09; p = 0.2) of the total heritability for OCD. The overlapping set of eQTLs identified in both muscle and brain accounted for 8% heritability in TS (h2 = 0.04; se = 0.08; p = 0.3) and 0% (h2 = 0.0000001; se = 0.06; p = 0.5) of total OCD heritability. Finally, the remaining non-eQTL portion of SNPs accounted for only 34% (h2 = 0.16; se = 0.16; p = 0.2) of TS heritability and 16% (h2 = 0.05; se = 0.08; p = 0.3) of OCD heritability (Table S9, Figure S10).
