PITX1 and colorectal cancer: Of the 33 SNPs in height-breast cancer clusters, 26 SNPs were annotated to the same gene in sets of two or more height- and breast cancer risk-associated SNPs, leading to 9 gene annotations: ID4, ZMIZ1, MCHR1 (in GRAIL)/MKL1 (in HapMap), ESR1, RAD51B, TNS1, TNP1, TET2 and FAM46A. Of the 15 SNPs in height-colorectal cancer clusters, 8 SNPs were annotated to the same gene in pairs of height- and colorectal cancer-risk associated SNPs, leading to the following four gene annotations: BMP2, PITX1, DCBLD1 and BARX1.
