Osteopontin promoter polymorphism is associated with increased carotid intima-media thickness.

ABSTRACT:

Background

Osteopontin (OPN)-transgenic mice exhibit increased carotid artery intima-media thickness (CIMT), smooth muscle cell proliferation, and atheroma formation.

Methods

An association of the human T-66G promoter variant with CIMT was examined in Caucasian adults grouped according to metabolic syndrome criteria: present (+MetS; n = 70) or absent (-MetS; n = 70).

Results

The G-allele frequency was 22%. For the entire cohort, the G group (TG and GG) was associated with significantly lower age-adjusted and gender-adjusted CIMT compared with the TT group (P = .008); similar analysis by metabolic syndrome group found a significant difference only in the -MetS group (P = .018). Stepwise multivariate regression showed that after age and waist circumference, the T-66G va
