Finally, we found that six druggable genes (HP, EHMT2, HLA‐DRA, MAP 3K3, NPC1, and RXRA) have a causal relationship with two or more sarcopenia‐related traits; 11 druggable genes (MFGE8, COL15A1, AURKA, NQO1, CTSS, SMAD3, AKR1C2, SLC22A4, CTNNB1, ADAM17, and LTB4R) have a causal relationship with sarcopenia from two or more QTL datasets (Table S11 and Figure S1). This evidence concerns the gene COL15A1 and sarcopenia.
