TMEM252

Chr 9

transmembrane protein 252

The protein encoded by TMEM252 is predicted to be a membrane-localized protein, though its specific cellular function remains unclear. Mutations in TMEM252 have been associated with neurodevelopmental disorders, though the clinical phenotype and inheritance pattern are not well-established from current data. This gene shows relatively low constraint against loss-of-function variants, suggesting tolerance to such mutations in the general population.

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.
