FIBIN

Chr 11

fin bud initiation factor homolog

FIBIN encodes a protein predicted to enable protein homodimerization and is located in the Golgi apparatus, endoplasmic reticulum, and extracellular region. However, no human diseases have been definitively associated with FIBIN mutations in the current literature. The clinical significance of variants in this gene remains to be established.

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.
