NDUFV2 and inflammatory bowel disease: Nine proteins with p < 0.05 for IVW were tentatively considered to be causally associated with IBD: prot‐a‐63 (apoptosis‐inducing factor 1, mitochondria), prot‐a‐1356 (hydroxymethylglutaryl‐CoA synthetase, mitochondria), prot‐a‐2026 (NADH dehydrogenase [ubiquinone] flavoprotein 2 (NDUFV2), mitochondria), prot‐a‐2190 (pyruvate carboxylase, mitochondria), prot‐a‐1942 (39S ribosomal protein L33, mitochondria), prot‐a‐1965 (peptide chain release factor 1‐like, mitochondria), prot‐a‐3015 (transmembrane protein 70, mitochondria).
