MMP25

Chr 16

matrix metallopeptidase 25

Also known as: MMP-25, MMP20, MMP20A, MMPL1, MT-MMP 6, MT-MMP6, MT6-MMP, MT6MMP

MMP25 encodes a membrane-type matrix metalloproteinase that degrades extracellular matrix components and inactivates alpha-1 proteinase inhibitor during inflammatory responses, facilitating neutrophil migration to inflammatory sites. The gene shows very low constraint against loss-of-function variants (pLI near zero), and no established Mendelian disease associations have been reported to date. Current evidence suggests this gene may not be critical for normal human development or associated with pediatric neurological disorders.

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.

GOFprediction above median

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.
