TRIM72
Chr 16tripartite motif containing 72
Also known as: MG53
The protein functions as a muscle-specific E3 ubiquitin ligase that plays a central role in cell membrane repair by nucleating assembly of repair machinery at injury sites and regulating membrane budding and exocytosis. Mutations in this gene cause limb-girdle muscular dystrophy, which is inherited in an autosomal recessive pattern. The gene shows very low constraint to loss-of-function variants (pLI near 0), suggesting haploinsufficiency is well-tolerated.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function 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.
