Estrogen receptor alpha (ESR1) gene variation is associated with a range of important estrogen-dependent characteristics, including responses of lipid profile and atherosclerotic severity to hormone replacement therapy, coronary heart disease risk, and migraine.
Qualitative assessment of previous evidence and an updated meta-analysis confirms lack of association between the ESR1rs2234693 (PvuII) variant and coronary heart disease in men and women.
This study seeks to investigate the association between the ESR1 haplotype created by the c.454-397 T>C and c.454-351 A>G polymorphisms, the length of the (TA)n repeats, and the angiographic extent of CAD.
