Primary immunodeficiency or monogenic inflammatory bowel disease
Gene: CFTR
In view that this gene is Green on non-CF bronchiectasis panel, although there is a Green external review it was decided to keep this gene Amber on this panel due recruitment categoryCreated: 6 Jul 2018, 4:43 p.m.

Clear evidence of causation. I see the relevance in terms of the bronchiectasis phenotype, however I am not clear on the relevance to the majority of those recruited under PID, as CF often presents independently of immunological anomalies. This gene is on the bronchiectasis panel, therefore if participants with PID have bronchiectasis (and this is captured in their HPO terms) they will get this gene via the non-CF bronchiectasis panel being concurrently applied.
Therefore I would rate this as amber for the PID panel, but would be happy to review this in the light of further comments or information.Created: 6 Jul 2018, 11:44 a.m.
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Phenotypes
Cystic fibrosis 219700
Suggest to include this gene in the PID panel because CF and immunodeficiency are both part of the differential diagnosis for bronchiectasis (and phagocyte dysfunction may contribute to the phenotype)Created: 29 Jun 2018, 4:15 p.m.
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Phenotypes
bronchiectasis; cystic fibrosis
Source IUIS Classification December 2019 was added to CFTR. Added phenotypes Respiratory infections, pancreatic insufficiency, elevated sweat chloride; Congenital defects of phagocyte number or function for gene: CFTR Publications for gene CFTR were updated from to 32048120; 32086639
2018-07-12 Louise Daugherty (Genomics England Curator) promoted panel to v1.0. Reviews were assessed, and panel was revised according to expert reviews and further in-house curation based on PanelApp guidelines. Previous panels (A- or hypo-gammaglobulinaemia, Congenital neutropaenia, Agranulocytosis, Combined B and T cell defect, Inherited complement deficiency and SCID panels) that were merged with this panel, were checked again for any changes/new reviews prior to versioning of this panel, these merged panels are now retired/made internal.
