DOK7

Chr 4AR

docking protein 7

Also known as: C4orf25, CMS10, CMS1B

The protein is essential for neuromuscular synaptogenesis, functioning in aneural activation of muscle-specific receptor kinase and subsequent clustering of acetylcholine receptors in myotubes. Mutations cause congenital myasthenic syndrome type 10 and fetal akinesia deformation sequence 3 through autosomal recessive inheritance. The pathogenic mechanism involves gain-of-function effects that disrupt normal neuromuscular junction development and function.

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.

GOFprediction above median
DNprediction 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.
