TOMM7
Chr 7ARtranslocase of outer mitochondrial membrane 7
Also known as: GMPGS, TOM7
The protein is a component of the translocase of the outer mitochondrial membrane (TOM) complex that is essential for importing cytosolically synthesized proteins into mitochondria and regulates the assembly and stability of the translocase complex. Mutations cause Garg-Mishra progeroid syndrome, an autosomal recessive disorder. The gene shows tolerance to loss-of-function variants (pLI 0.01, LOEUF 1.76), suggesting that complete loss of function may be required for disease manifestation.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
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.
