SSX3

Chr X

SSX family member 3

Also known as: CT5.3

The SSX3 protein functions as a transcriptional repressor that modulates gene expression. No definitive disease associations have been established for SSX3 mutations in the provided clinical data. The gene shows tolerance to loss-of-function variants (pLI 0.009, LOEUF 1.28), suggesting that complete loss of SSX3 function may not cause severe developmental disorders.

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.

GOFprediction above median

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.
