HSPA1A and coronary artery disorder: To comprehensively evaluate the potential implications of 2 single nucleotide polymorphisms (SNPs) of HSPA1A gene (−110A/C and +190G/C polymorphisms) in the etiology of CHD, we conducted a large-scale case-control study of 1,003 CHD cases and 1,003 age- and sex- frequency matched controls in a Chinese population.
