panel promoted to version 1

Rebecca Foulger (Genomics England curator)

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.
