PRR5L
Chr 11proline rich 5 like
Also known as: PROTOR2
The protein associates with the mTORC2 complex and regulates its activity in a substrate-specific manner, controlling cellular processes including cytoskeletal organization, cell survival, and cell migration. Mutations in this gene cause microcephaly, developmental delay, and seizures with autosomal recessive inheritance. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.637), suggesting some intolerance to complete protein loss.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
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.
