SPATA31A7

Chr 9

SPATA31 subfamily A member 7

Also known as: AEP1, C9orf36, C9orf36A, FAM75A4, FAM75A7, SPATA31A4

The protein is predicted to be involved in cell differentiation and spermatogenesis and is located in cellular membranes. SPATA31A7 mutations have not been clearly established as a cause of human disease based on the available information. The inheritance pattern and clinical phenotypes associated with this gene remain to be determined.

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.
