Inheritance of pancreatic cancer in pancreatic cancer-prone families.

Abstract

Families are being increasingly recognized as carrying an inherited susceptibility for pancreatic cancer, apparently unrelated to any currently recognized syndrome. The authors provide a review of the current evidence for familial susceptibility to pancreatic cancer. A formal segregation analysis of the pattern of inheritance of pancreatic cancer in 70 families from the National Registry for Familial Pancreatic Cancer is described. This analysis suggests a single major gene with an autosomal dominant mode of inheritance controlling susceptibility for pancreatic cancer in these families.
