Abstract

The first data on the existence of multiple genomic rearrangements, such as copy number variation (CNV) and copy neutral loss of heterozygosity, in vascular tissues and peripheral blood leukocytes from patients with atherosclerosis, are presented. Compared to internal mammary arteries and peripheral blood leukocytes, right coronary arteries in the atherosclerotic plaque area presented with a higher CNV length and number of genes located in their vicinity. In each of the patients, 6–16% of CNVs were common to the three types of tissues examined. Therefore, most of the copy number variations in the tissues affected by atherosclerosis (from 68 to 91% in each of the patients) were of somatic origin. The gains in 3p21.31 (CACNA2D2), 7q32.1 (FLNC), 19p13.3 (C19orf29, PIP5K1C), and 21q22.3 (COL6A1) were detected in vascular tissues but not in peripheral blood leukocytes. Moreover, the gain in 7p15.2 (SKAP2), detected in the patients with atherosclerosis, did not overlap with any CNV regions currently reported in The Database of Genomic Variants. The loss of heterozygosity in 12 out of 13 chromosomal regions was copy neutral and covered tumor suppressor genes (SFRP1, CEBPD, RB1CC1, DIRAS3, TUSC3, and ZDHHC2).
