ATM and familial pancreatic carcinoma: Genetic mutations of damaged DNA repair genes such as BRCA1/2, partner and localizer of BRCA2 (PALB2), and the ataxia-telangiectasia mutated (ATM) gene along with the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene (familial atypical multiple mole and melanoma syndrome) and mismatch repair genes (Lynch syndrome) are associated with significantly increased risk of pancreatic cancer.
