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). Here, HLA-DQB2 is linked to sarcopenia.
