(1) In the colocalization analysis of CAD, it was observed that for these nine plasma proteins (LAYN, KPNA2, GCKR, MSMP, ADH1B, A4GNT, COL6A3, KLC1, CALB2), there may not be shared causal variants in the region associated with CAD (PPH3 + PPH4 < 0.8). The gene discussed is A4GNT; the disease is coronary artery disorder.
