In a preliminary study using Affymetrix 250K, we established a link on chromosome (chr) 3, which harbors the GATA2 gene, to early onset of CAD in two families with heterozygous familial hyperlipidemia (HFH), suggesting a role for the gene in metabolic-related CAD in the general population.
The HNRPUL1 gene rs11881940T and GATA2 gene rs3803T loci were highly correlated with CAD (P < 0.05). rs10757278G increased the risk of CAD in patients indicated by an odds ratio (OR) = 1.242 [95% confidence interval (CI) = 1.04-1.49]; rs11881940T and rs3803T were protective factors for CAD with ORs = 0.767 (95%CI = 0.61-0.97) and 0.53 (95%CI = 0.40-0.72), respectively.
These observations identify GATA2 as a novel susceptibility gene for coronary artery disease and suggest that the study of this transcription factor and its downstream targets may uncover a regulatory network important for coronary artery disease inheritance.
