Initial gene list and info collated by Sian Ellard, University of Exeter Medical School, August 2018 on behalf of the GMS Endocrinology specialist test group. Gene Symbol submitted: HNF1B; Suggested intial gene rating: Green; Evidence for inclusion: none given; Evidence for exclusion: none given; Technical notes (e.g. non-coding/CNV mutations requiring coverage?): none given; Phenotypes: Transient neonatal diabetes, pancreatic atrophy, mild exocrine insufficiency and low BW.Created: 11 Jan 2019, 4:27 p.m.
We have 2 additional cases that have been identified by our lab.Created: 29 May 2017, 8:34 a.m.
Comment when marking as ready: Marked as Ready: 29th May 2017.Created: 29 May 2017, 8:36 a.m.
Comment on list classification: Updated rating from Red to Green: 2 published cases supporting gene:disease association (Yorifuji and Edghill), and 2 further cases reported by Dr Elisa De Franco as part of Exeter neonatal diabetes screen.Created: 29 May 2017, 8:36 a.m.
PMID:15181075 (Yorifuji et al, 2004) describe a missense mutation in HNF1B (C443G, S148W) in two siblings: one with neonatal diabetes mellitus and one with neonatal polycystic, dysplastic kidneys (with transient hyperglycemia which resolved spontaneously). This is the first report of permanent neonatal diabetes caused by a mutation of HNF1B.Created: 24 Apr 2017, 9:51 a.m.
Comment on mode of inheritance: Monoallelic mode of inheritance supported by literature.Created: 24 Apr 2017, 9:42 a.m.
PMID:17116179 (Edghill et al., 2006) identified a heterozygous S148L HNF1B mutation in one patient with neonatal diabetes diagnosed at 17 days.Created: 24 Apr 2017, 9:40 a.m.
Added 'mosaicism' tag based on PMID:15181075 (Yorifuji et al) which showed germline mosaicism of HNF1B; the unaffected mother was a low-level mosaic of normal and mutant HNF1B.Created: 24 Apr 2017, 9:24 a.m.
Phenotypes for gene: HNF1B were changed from Transient neonatal diabetes; transient neonatal diabetes mellitus (TNDM); permanent neonatal diabetes mellitus; Diabetes mellitus, noninsulin-dependent, 125853; Transient neonatal diabetes, pancreatic atrophy, mild exocrine insufficiency and low BW to Transient neonatal diabetes mellitus (disease), MONDO:0020525; permanent neonatal diabetes mellitus, MONDO:0100164; Type 2 diabetes mellitus, OMIM:125853; transient neonatal diabetes, pancreatic atrophy, mild exocrine insufficiency and low BW
Phenotypes for gene: HNF1B were changed from Transient neonatal diabetes; transient neonatal diabetes mellitus (TNDM); permanent neonatal diabetes mellitus; Diabetes mellitus, noninsulin-dependent, 125853 to Transient neonatal diabetes; transient neonatal diabetes mellitus (TNDM); permanent neonatal diabetes mellitus; Diabetes mellitus, noninsulin-dependent, 125853; Transient neonatal diabetes, pancreatic atrophy, mild exocrine insufficiency and low BW

Promoted panel to Version 1: 31st May 2017. This panel is largely aligned with the Exeter Molecular Genetics Laboratory neonatal diabetes screen. Note that 8 genes feature on the Exeter 8-gene panel for patients with 'neonatal diabetes and autoimmune disease' (FOXP3, IL2RA, ITCH, LRBA, SIRT1, STAT1, STAT3 and STAT5). ITCH, SIRT1, STAT1 and STAT5A/B do not feature on this panel following correspondance with Elisa De-Franco (University of Exeter Medical School) that, at the time of curation, none of the patients with mutations in ITCH, SIRT1, STAT1 and STAT5b had diabetes diagnosed in the neonatal period, and therefore there is currently insufficient evidence to include these genes in this neonatal diabetes panel.
Phenotypes for HNF1B were set to Transient neonatal diabetes; transient neonatal diabetes mellitus (TNDM); permanent neonatal diabetes mellitus; Diabetes mellitus, noninsulin-dependent, 125853
This gene has been classified as Green List (High Evidence).
