TPD52L3 and colorectal carcinoma: Thus far, genome-wide association studies (GWAS) have identified around 100 loci associated with sporadic CRC, in or proximal to known CRC-related genes and pathways (e.g., BMP2, BMP4, SMAD7, CCND2, GREM1) and in genes not previously linked to CRC (CDKN1A, EIF3H, TPD52L3, ITIH2, LAMA5, and LAMC1) (6, 7).
