Furthermore, genome-wide association studies of adult leukocyte TL (LTL) identified 7 single-nucleotide variations (ACYP2, NAF1, OBFC1, RTEL1, TERC, TERT, ZNF208) linked with LTL that mutually project towards an increased risk for coronary artery disease.7 This evidence concerns the gene RTEL1 and coronary artery disorder.
