The role of PRKCH gene variants in coronary artery disease in a Chinese population.

The aim of the present study was to assess the influences of PRKCH gene variants (1425G/A and _15) on the risk of coronary artery disease (CAD) in a Chinese population. Our study population consisted of 470 CAD patients and 434 control subjects. The alleles frequencies of the two variants were significantly higher among CAD patients than control subjects (P = 0.001 for 1425G/A and P = 0.001 for _15, respectively). In the CAD group, the A allele carriers of 1425G/A and _15 polymorphisms had higher low-density lipoprotein cholesterol (LDL-C) levels than homozygote G allele carriers (P = 0.001 and P = 0.021, respectively). In a multiple logistic regression model adjusted for age, sex, body mass index (BMI), etc., a markedly increased risk of developing CAD was found in subjects carrying GA or AA genotype (P = 0.005 and P = 0.018, respectively). In conclusion, we observed that there was a remarkable association of minor alleles (1425G/A and _15) in the PRKCH gene with an elevated risk of CAD and increased levels of LDL-C in this Chinese population.
