COL4A1 and coronary artery disorder: A recent GWA meta-analysis from the CARDIoGRAM Consortium with some overlapping cohorts to those in our study, reports discovery of three of these loci [12]: COL4A1/COL4A2, ZC3HC1, CYP17A1. The P values observed for the lead variants at these loci in the current study were: COL4A1/COL4A2: rs4773144, P = 3.5×10−8; ZC3HC1: rs11556924, P = 3.1×10−7; CYP17A1: rs3824755, P = 1.2×10−7, providing further strong evidence for the association of these loci with CAD.
