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). This evidence concerns the gene TMEM70 and inflammatory bowel disease.
