This included specific HLA genes, here listed with the tissue in which the strongest eQTL was found (HLA-DQA2—skeletal Muscle, HLA-DQB2—whole blood, HLA-DQB1—whole blood, HLA-DRB6—skeletal muscle, HLA-DRB9—thyroid, HLA-DRB1—skin, sun-exposed lower leg, and HLA-DQA1—lung), in addition to other genes with plausible mechanisms of action in sarcopenia (ATF6B—skeletal muscle, CYP21A1P—subcutaneous adipose, BAG6—tibial artery, CSNK2B—left heart ventricle, LY6G5C—thyroid, PSORS1C1—thyroid, C2—testis). This evidence concerns the gene ATF6B and sarcopenia.
