ABLIM2
Chr 4actin binding LIM protein family member 2
The protein acts as a scaffold protein that binds actin filaments and stimulates transcriptional activity through the SRF pathway, playing a role in cellular structure and gene regulation. Mutations cause autosomal recessive intellectual disability with seizures and dysmorphic features. This gene is highly constrained against loss-of-function variants, suggesting that complete protein loss is likely pathogenic.
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.
