PIP5KL1

Chr 9

phosphatidylinositol-4-phosphate 5-kinase like 1

Also known as: PIPKH

The protein acts as a scaffold to localize and regulate type I PI(4)P 5-kinases to specific cellular compartments, where they generate PI(4,5)P2 for actin nucleation, signaling and scaffold protein recruitment. PIP5KL1 mutations cause disease through a predicted gain-of-function mechanism, though the specific associated disorder and inheritance pattern are not provided in the available data.

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.
