Primary immunodeficiency or monogenic inflammatory bowel disease
Gene: PSMB9Comment on mode of inheritance: Updated MOI from biallelic to monoallelic as all cases reported to date have harboured heterozygous variants in this gene (PMID: 26524591; 33727065; 34819510)Created: 11 Jan 2022, 2:10 p.m. | Last Modified: 11 Jan 2022, 2:10 p.m.

Kanazawa et al., 2021 (PMID: 34819510) identified a further two unrelated Japanese patients with the same de novo PSMB9 heterozygous missense variant as that identified in the previous study (c.467G>A/p.G156D). Both individuals displayed severe autoinflammatory phenotypes and pulmonary hypertension and later also manifested combined immunodeficiency with periodic inflammatory exacerbation. The variant lead to impaired immunoproteasome maturation and activity, and the proteasome defect and immunodeficient phenotypes were recapitulated in Psmb9(G156D/+) mice.Created: 11 Jan 2022, 2:07 p.m. | Last Modified: 11 Jan 2022, 2:07 p.m.

PMID: 33727065 (2021) - a de novo PSMB9 p.G156D variant identified in a 1-month old boy who developed fever, a chilblain-like skin rash, myositis, and severe pulmonary hypertension due to the hyperactivation of IFN-α. In vitro experiments using patient-derived primary cells and cell lines transduced with the mutant gene revealed reduced proteasome activities. The patient responded to treatment with a Janus kinase inhibitor, tofacitinib, and later received stem cell transplantation - following which he no longer required tofacitinib and experienced no disease recurrence.Created: 27 Sep 2021, 3:56 p.m. | Last Modified: 27 Sep 2021, 3:56 p.m.

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Phenotypes

Gene was flagged as requiring further clinical input from the Immunology Test Group, but no additional information was submitted to support the Green rating. In view of a lack of clear evidence the current recommendation is Amber.Created: 12 Nov 2019, 5:04 p.m. | Last Modified: 12 Nov 2019, 5:04 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. Evidence /opinion needs consensus before upgrading to Green

Comment on list classification: Changed from Amber to Red until more info to support gene-disease association. Expert review notes that is it currently it is thought variants contribute to CANDLE syndrome but not reported as a stand-alone disorder. Gene not present on any other PID related panels or within ESID or IUIS classifications. Request evidences / immunological association of this gene from Victorian Clinical Genetics Services.Created: 5 Jul 2018, 10:15 a.m.
Comment on list classification: 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 from Victorian Clinical Genetics Services. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1. No disorder or MOI was listed in the submitted list.Created: 26 Jun 2018, 12:45 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.
