Common variants in the periostin gene influence development of atherosclerosis in young persons.

ABSTRACT:

Objective

We investigated the influence of genetic variants (rare and common) in the gene encoding periostin (POSTN) on atherosclerosis as measured in arterial specimens from the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) study.

Methods and results

A comprehensive survey of common POSTN variants (87 single-nucleotide polymorphisms [SNPs]) in PDAY subjects (n = 2527) identified numerous SNPs associated with raised lesions in abdominal aorta and with fatty streaks in thoracic aorta. These SNPs belonged to a small number of correlation bins that spanned the entire locus. To examine effects of rare variants, we resequenced POSTN functional regions in PDAY cases with raised lesions (n = 291) and controls with no raised lesions (n = 294). However, we found no
