DOK3

Chr 5

docking protein 3

Also known as: DOKL

Predicted to be involved in Ras protein signal transduction and cell surface receptor protein tyrosine kinase signaling pathway. Predicted to be located in ficolin-1-rich granule membrane and plasma membrane. Predicted to be active in cytoplasm. Implicated in colorectal adenocarcinoma.

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.
