Review on behalf of Jayne Houghton and Kevin Colclough, Exeter Genomics Laboratory, SWGLH. Seven cases of hyperinsulinaemic hypoglycaemia with de novo NSD1 mutations have reported to date (Grand et al 2019 Am J Med Genet PMID:30719864). In addition, the Exeter laboratory has identified a further 3 cases referred with neonatal hypoglycaemia as part of a syndrome in which NSD1 de novo variants have been identified.Created: 14 Sep 2022, 4:39 p.m. | Last Modified: 14 Sep 2022, 4:39 p.m.

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with a phenotype in OMIM and Gene2Phenotype (Definitive). There is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.Created: 3 Dec 2021, 4:14 p.m. | Last Modified: 3 Dec 2021, 4:14 p.m.
