Abstract excerpt
In vivo characterization of regulatory polymorphisms is a key requirement for next-generation human genetic analysis. Here we describe haploChIP, a method that uses chromatin immunoprecipitation (ChIP) and mass spectrometry to identify differential protein-DNA binding in vivo associated with allelic variants of a gene. We demonstrate this approach with the imprinted gene SNRPN. HaploChIP showed close correlation...
