Maturity-onset diabetes of the young 5 (MODY5) is a rare diabetes syndrome of young adults, characterized by diabetic ketosis, multiple renal cysts, and hypokalemia. Mutations in the HNF1B gene are associated with MODY5.
BackgroundMaturity-onset diabetes of the young 5 (MODY5), a rare diabetes syndrome of young adults, is associated with variants in hepatocyte nuclear factor 1B (HNF1B) gene. Case PresentationWe reported a case of MODY5, which presented with diabetic ketosis, multiple renal cysts, and hypokalemia. In this case, the HNF1B score was estimated as 13 and a heterozygous variant of HNF1B in exon 4 (c.826C>T, p.Arg276*) was identified through Sanger sequencing. ConclusionsMultiple renal cysts and youth-onset diabetes are common manifestations in patients with HNF1B mutations, and insufficient insulin secretion may be a potential cause of diabetic ketosis in MODY5.
