Journal Article

OBJECTIVE: How 9p21 variation affects risk of cardiovascular disease is unclear, so we assessed whether 9p21 variants are associated with arterial elasticity or retinal microvascular findings. METHODS: In the prospective Multi-Ethnic Study of Atherosclerosis (MESA) we assessed 378 SNPs in the 9p21 locus. Within four ethnic groups, we used an additive genetic model to relate the 9p21 SNPs to five vascular phenotypes: small and large elasticity derived from radial diastolic pulse contour analysis; Young's elastic modulus from carotid artery ultrasound measurements; and the diameter of the central retinal arteries and veins. RESULTS: In neither ethnic-specific nor pooled data was there any statistically significant association between any of the 9p21 SNPs and any of the five vascular phenotypes. CONCLUSION: Our study does not support an association of 9p21 variation with arterial elasticity or retinal microvascular abnormalities.
