YIPF1

Chr 1

Yip1 domain family member 1

Also known as: DJ167A19.1, FinGER1, YIPFbeta3A, Yip5a

The protein is predicted to bind small GTPases and participate in vesicle-mediated transport between cellular compartments including the Golgi apparatus. Mutations cause an autosomal recessive neurodevelopmental disorder characterized by intellectual disability, developmental delay, and seizures. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.77), suggesting some tolerance to functional disruption.

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.

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.
