For seven genes (ALDH1A2, CHMP1A, CRADD, FAM53A, LTBP1, RPP25, and TGFA), we found evidence that GWAS signals for osteoarthritis colocalize with mQTLs in these genes and are additionally associated with gene expression levels in the same tissue. The gene discussed is ALDH1A2; the disease is osteoarthritis.
