Assessment of the 9p21.3 locus in severity of coronary artery disease in the presence and absence of type 2 diabetes.

ABSTRACT:

Background

The 9p21.3 locus is strongly associated with the risk of coronary artery disease (CAD) and with type 2 diabetes (T2D). We investigated the association of 9p21.3 variants with severity of CAD (defined by the number of vessel diseased [VD]) in the presence and absence of T2D.

Methods

We tested 11 9p21.3-variants for association in a white Italian study (N = 2,908), and carried out replication in 2 independent white populations, a German study (N = 2,028) and a Canadian Study (N=950). SNP association and permutation analyses were conducted.

Results

We identified two 9p21.3-variants, rs4977574 (P < 4×10(-4)) and rs2383207 (P < 1.5×10(-3)) that were associated with severity of CAD in subjects without T2D. Association of rs4977574 with severity of CAD was confirm
