Variants of the PPARD gene and their clinicopathological significance in colorectal cancer.

ABSTRACT:

Background

Peroxisome proliferator-activated receptor delta (PPARD) is nuclear hormone receptor involved in colorectal cancer (CRC) differentiation and progression. The purpose of this study was to determine prevalence and spectrum of variants in the PPARD gene in CRC, and their contribution to clinicopathological endpoints.

Methods and findings

Direct sequencing of the PPARD gene was performed in 303 primary tumors, in blood samples from 50 patients with ≥ 3 affected first-degree relatives, 50 patients with 2 affected first-degree relatives, 50 sporadic patients, 360 healthy controls, and in 6 colon cancer cell lines. Mutation analysis revealed 22 different transversions, 7 of them were novel. Three of all variants were somatic (c.548A>G, p.Y183C, c.425-9C>T, and c.628-16G>
