maturity-onset diabetes of the young type 6 (MONDO_0011668, a Monarch Disease Ontology identifier) is monogenic diabetes caused by inactivating mutation(s) in the gene NEUROD1, encoding neurogenic differentiation 1. In addition to diabetes, this condition may be associated with neurogenic anomalies. Homozygous NEUROD1 mutations result in permanent neonatal diabetes. Also known as: MODY type 6, MODY6, NEUROD1 maturity-onset diabetes of the young (disease), NEUROD1-associated monogenic diabetes, maturity onset diabetes of the Young, type 6, maturity-onset diabetes of the young (disease) caused by mutation in NEUROD1, maturity-onset diabetes of the young 6, neurogenic differentiation Factor 1-associated monogenic diabetes.
