Familial Hirschsprung Disease
Gene: NKX2-1
Comment on list classification: Updated rating from Red to Amber after discussion with Helen Brittain: 1 red review. 3 variants reported in PMID:15548547 and PMID:17640327 but insufficient family tree/additional information in the papers to currently use this gene in tiering. Added 'watchlist' tag to collate further information.Created: 28 Aug 2017, 9:21 a.m.
PMID:15548547 (2005) identified a Chinese patient with HSCR who was heterozygous for a gly322-to-ser (G322S) mutation in the TITF1 (NKX2-1) gene. The authors further analyzed TITF1/NKX2-1 (PMID:17640327, 2007) and identified a M3L mutation in 2 Australian HSCR patients.Created: 5 Jun 2017, 3:10 p.m.

18th October 2017: Revised and approved to Version 1.0 after expert and curator review. An expert list from Mr. Simon Kenny and Professor Robert Hofstra's groups (Alder Hey - Erasmus MC) formed the basis of the original panel. The expert list was then expanded based on a review of literature. Many of the literature genes remain red on the V1.0 panel as they were identified through association studies and/or they represent susceptibility/risk factors for Hirschsprung's disease (HSCR). Sumita Chhabra (Alder Hey) and Erwin Brosens (Erasmus) provided extensive feedback for genes on the panel, together with reviews from Merce Garcia-Barcelo.
This gene has been classified as Amber List (Moderate Evidence).
