Three unrelated families reported. Note cryptic 3' deletion identified in one. We have included this gene on our 'systemic auto inflammatory disease' panel (as well as a number of other panels aimed at the principal presenting features). As other similar disorders such as Aicardi-Goutieres syndrome are included in the PID panel, there is an argument to be made about consistency.Created: 12 Apr 2020, 4:31 a.m. | Last Modified: 12 Apr 2020, 4:31 a.m.

Gene was flagged as requiring further clinical input from the Immunology Test Group, but no additional information was submitted to support the Green rating.

Pseudo TORCH syndrome: Aicardi-Goutiere like - severe intracranial haemorrhage, thrombocytopaenia, seizures, liver failure caused by interferon activation - probable green association, is it a relevant phenotype?
2 families (one homozygous, one compound het where one variant was the same as the first family with possible common ancestor) - borderline, with lack of USP18 expression - abnormal activation of the immune system (interferon) - is this a likely presentation in immunology clinic?Created: 26 Sep 2019, 4 p.m. | Last Modified: 26 Sep 2019, 4 p.m.

Comment on list classification: Changed rating from Red to Amber to reflect the agreed rating agreed by the GMS Immunology Specialist Test Group, but flagged for further follow up with the Immunology Test Group due to the subsequent conflicting review.

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.
