Primary immunodeficiency or monogenic inflammatory bowel disease
Gene: MPO
deficiency of MPO is usually asymptomatic, and not classified as an immunodeficiency by the IUISCreated: 29 Jun 2018, 2:40 p.m.
Comment on list classification: Comment on list classification: PMID 3208230 outlines the role of neutrophil extracellular traps (NETs) in the control of some pathogens including viruses, by virus capture and neutralization. In vivo treatment of the mice with DNase resulted in the enhanced susceptibility of IFNAR-/- mice to the CHIKV virus. Furthermore, the levels of MPO-DNA complex in acutely CHIKV-infected patients, were correlated with the levels of NETs and the viral load in the blood, suggesting that NETs are also released in natural human infection cases. Therefore, variants that result in myeloperoxidase deficiency, may well contribute to an increased susceptiblity to viral infection. At least 9 variants have been reported in Myeloperoxidase deficiency 254600 and these could well be contributing to increased viral susceptibily.Created: 7 Apr 2020, 4:36 p.m. | Last Modified: 7 Apr 2020, 4:36 p.m.
Panel Version: 2.44
Associated with phenotype in OMIM and not in Gen2Phen. At least 9 variants identified. Although the phenotype may not be directly relevant for this panel, patients may be recruited under this heading with recurrent fungal infections (Helen Britain).Created: 8 May 2018, 10:38 a.m.
Comment on list classification: Changed from Amber to Red based on external clinical expert review and review of the literature. Deficiency of MPO is notes as asymptomatic, and not classified as an immunodeficiency by the IUIS, but it is noted on the ESID classification list.

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.Created: 20 Apr 2018, 12:25 p.m.

Gene: mpo has been classified as Amber List (Moderate Evidence).
Publications for gene: MPO were set to 15108282; 9354683; 9637725
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: mpo has been classified as Red List (Low Evidence).
