Serine/Threonine Kinase and its Role in Pancreatic Risk.

Next-generation sequencing has led to the recent discovery of several novel pancreatic cancer susceptibility genes. These genes include ataxia telangiectasia mutated (), a serine/threonine kinase that is an integral component of DNA repair. Pathogenic germline variants are frequently identified in patients with pancreatic ductal adenocarcinoma (PDAC) with and without a family history of the disease. Loss of is also a frequent somatic event in the development of PDAC. These discoveries have advanced our understanding of the genetic basis of pancreatic cancer risk and will impact patient care through appropriate patient-risk stratification; personalized screening and early detection efforts; and, for some, targeted therapy.
