DUSP16
Chr 12dual specificity phosphatase 16
Also known as: MKP-7, MKP7
This gene encodes a dual specificity protein phosphatase that inactivates MAP kinases by dephosphorylating both serine/threonine and tyrosine residues, specifically regulating the JNK and ERK signaling pathways. Mutations cause autosomal recessive intellectual disability with seizures and brain malformations. The gene shows significant constraint against loss-of-function variants (LOEUF 0.502), suggesting intolerance to complete protein loss.
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.
