FAMILIAL ISLET-CELL ADENOMATOSIS

Abstract Familial multiple adenoma of pancreatic beta-cells is described for the first time. The occurrence of diabetes mellitus in different members of the family raises the possibility of a common genetic origin for the multiple islet-cell adenomas and the diabetic trait. The evidence suggests that this gene is autosomal and dominant, that it is not linked with the HLA antigens, and that it causes an abnormal sensitivity of the beta-cells, which become hyperplastic or hypofunctional.
