USP43
Chr 17ubiquitin specific peptidase 43
The USP43 protein is a deubiquitinating enzyme that cleaves ubiquitin from target proteins and processes polyubiquitin precursors, and may also have ISG15-specific peptidase activity involved in DNA repair processes. This gene is highly constrained against loss-of-function variants (LOEUF 0.398), but no definitive human disease associations have been established for USP43 mutations. Further research is needed to determine the clinical significance of variants in this gene.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
