Comment on list classification: New gene added by Zornitza Stark. Sufficient number of unrelated cases (5 - PMIDs: 33224153; 28422754) with immunopathology and distinct biallelic variants in this gene to rate as Green at the next GMS panel update. Supported by functional evidence and animal model.

MPEG1 is also associated with a relevant phenotype in OMIM (MIM# 619223)

Green List (high evidence)

Immunodeficiency-77 (IMD77) is an immunologic disorder characterized by recurrent and persistent polymicrobial infections with multiple unusual organisms. Skin and pulmonary infections are the most common, consistent with increased susceptibility to epithelial cell infections. The age at onset is highly variable: some patients have recurrent infections from childhood, whereas others present in late adulthood. The limited number of reported patients are all female, suggesting incomplete penetrance or a possible sex-influenced trait. Patient cells, mainly macrophages, show impaired killing of intracellular bacteria and organisms, including nontubercular mycobacteria, although there is also impaired killing of other organisms, such as Pseudomonas, Candida, and Aspergillus.

Four individuals reported, functional data, including animal model.
