Hepatic adenomatosis in a young woman with non-familial maturity-onset diabetes of the young type 3.

ABSTRACT

Hepatic adenomatosis (HA) is a rare condition in which multiple adenomas exist in an otherwise healthy liver. The most common subtype (H-HA) is associated with bi-allelic, somatic hepatic nuclear factor 1-alpha (HNF1A) mutations. Maturity-onset diabetes of the young type 3 (MODY3) is most often seen in young individuals with heterozygous, germline mutations in HNF1A. In this report, we describe a 17-year-old woman with H-HA and non-familial MODY3.
