Gastrointestinal epithelial barrier disorders
Gene: COL7A1Comment on list classification: Internal review from the Genomics England clinical team has advised this gene be made amber, as although there is evidence for gastrointestinal phenotypes in patients who are homozygous for variants in this gene, the skin phenotype more commonly associated with Epidermolysis bullosa is severe and would likely be picked up elsewhere.Created: 25 Jul 2018, 1:17 p.m.
Comment on list classification: Promoted from red to green due to expert review. Strong evidence for its role in Dystrophic epidermolysis bullosa, of which the recessive form includes features of inflammatory bowel disease.Created: 12 Oct 2016, 9:54 a.m.
Comment on mode of inheritance: The more severe (autosomal recessive) form of Dystrophic epidermolysis bullosa includes gastrointestinal clinical features such as esophageal blisters, esophageal strictures, dysphagia, anal blisters and constipation.Created: 12 Oct 2016, 9:52 a.m.

Panel reviews have been assessed and internal clinical team opinion has been sought on this panel, particularly to rule out incidental findings. Panel has been revised through expert review, internal review and literature research. 25/07/2018
Gene: col7a1 has been classified as Amber List (Moderate Evidence).
