In vitro scan for enhancers at the TCF7L2 locus.

ABSTRACT:

Aims/hypothesis

Recent functional characterisations of genome-wide association study (GWAS) loci suggest that cis-regulatory variation may be a common paradigm for complex disease susceptibility. Several studies point to a similar mechanism at the transcription factor 7-like 2 (TCF7L2) GWAS locus for type 2 diabetes. To address this possibility, we carried out an in vitro scan of this diabetes-associated locus to fine-map cis-regulatory sequences within this genomic interval.

Methods

A systematic cell-based enhancer strategy was employed to interrogate all sequences within the 92 kb type-2-diabetes-association interval for cis-regulatory activity in a panel of cell lines (HCT-116, Neuro-2a, C2C12, U2OS, MIN6 and HepG2). We further evaluated chromatin state at a subset of the
