For example, cluster 7 was genetically correlated with cystatin C (rg = 1; P = 0.005), cluster 9 was genetically correlated with homocysteinemia (HCY) (rg = 1; P = 0.006), and cluster 15 had genetic correlations with mean corpuscular volume (MCV) (rg = -0.923; P = 6.81 × 10−11) and hemoglobin (rg = -0.469; P = 0.030). This evidence concerns the gene CST3 and hyperhomocysteinemia.
