Transcription factor 7-like 2 (TCF7L2) variant is associated with familial breast cancer risk: a case-control study.

ABSTRACT:

Background

The transcription factor 7-like 2 (TCF7L2) is a critical component of the Wnt/beta-catenin pathway. Aberrant TCF7L2 expression modifies Wnt signaling and mediates oncogenic effects through the upregulation of c-MYC and cyclin D. Genetic alterations in TCF7L2 may therefore affect cancer risk. Recently, TCF7L2 variants, including the microsatellite marker DG10S478 and the nearly perfectly linked SNP rs12233372, were identified to associate with type 2 diabetes.

Methods

We investigated the effect of the TCF7L2 rs12255372 variant on familial breast cancer (BC) risk by means of TaqMan allelic discrimination, analyzing BRCA1/2 mutation-negative index patients of 592 German BC families and 735 control individuals.

Results

The T allele of rs12255372 showed an assoc
