This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.

Source IUIS Classification December 2019 was added to CFHR4. Mode of inheritance for gene CFHR4 was changed from Unknown to BOTH monoallelic and biallelic, autosomal or pseudoautosomal Added phenotypes Older onset atypical hemolytic-uremic syndrome, disseminated neisserial infections for gene: CFHR4 Publications for gene CFHR4 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.
Phenotypes for gene CFHR4 were set to Age related macular degeneration, Atypical hemolytic uremic syndrome susceptibility, Older onset atypical hemolytic-uremic syndrome, disseminated neisserial infections, Complement Deficiencies
Gene: cfhr4 has been classified as Amber List (Moderate Evidence).
