After staged analyses including a total of 3,164 cases and 20,134 controls, we identified 3 novel PAD susceptibility loci at IPO5/RAP2A, EDNRA and HDAC9 with genome wide significance (combined P = 6.8 x 10−14, 5.3 x 10−9 and 8.8 x 10−8, respectively). The gene discussed is EDNRA; the disease is peripheral arterial disease.
