Genetically predicted expression levels of PARK7 were inversely associated with IBD risk in sigmoid colon (OR 0.69, 95% CI 0.52–0.92; P = 0.014) and transverse colon tissue (OR 0.67, 95% CI 0.53–0.84; P = 6.56 × 10−4) (Table S19). The gene discussed is PARK7; the disease is inflammatory bowel disease.
