Evidence for GALNT12 as a moderate penetrance gene for colorectal cancer.

ABSTRACT: Characterizing moderate penetrance susceptibility genes is an emerging frontier in colorectal cancer (CRC) research. GALNT12 is a strong candidate CRC-susceptibility gene given previous linkage and association studies, and inactivating somatic and germline alleles in CRC patients. Previously, we found rare segregating germline GALNT12 variants in a clinic-based cohort (N = 118) with predisposition for CRC. Here, we screened a new population-based cohort of incident CRC cases (N = 479) for rare (MAF ≤1%) deleterious germline GALNT12 variants. GALNT12 screening revealed eight rare variants. Two variants were previously described (p.Asp303Asn, p.Arg297Trp), and additionally, we found six other rare variants: five missense (p.His101Gln, p.Ile142Thr, p.Glu239Gln, p.Thr286Met, p.Val290Phe) and o
