Primary immunodeficiency or monogenic inflammatory bowel disease
Gene: IRF2BP2
Comment on list classification: As reviewed by Hannah Knight, there are four unrelated cases in support of the association of monoallelic IRF2BP2 variants with immunodeficiency. Hence, this gene can be promoted to green rating in the next GMS review.Created: 12 Oct 2023, 8:36 p.m. | Last Modified: 12 Oct 2023, 8:36 p.m.

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.
Gene: irf2bp2 has been classified as Red List (Low Evidence).
Phenotypes for gene: IRF2BP2 were set to Recurrent infections, possible autoimmunity and inflammatory disease; Predominantly Antibody Deficiencies; CVID
Publications for gene: IRF2BP2 were set to 27016798
Mode of inheritance for gene: IRF2BP2 was changed from to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
