Genes affected

DOK5 (HGNC:16173): (docking protein 5) The protein encoded by this gene is a member of the DOK family of membrane proteins, which are adapter proteins involved in signal transduction. The encoded protein interacts with phosphorylated receptor tyrosine kinases to mediate neurite outgrowth and activation of the MAP kinase pathway. Unlike other DOK family proteins, this protein does not interact with RASGAP. This protein is up-regulated in patients with systemic sclerosis and is associated with fibrosis induced by insulin-like growth factor binding protein 5. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jun 2014]

Ambry Genetics

Dec 19, 2022

The c.757C>T (p.R253W) alteration is located in exon 7 (coding exon 7) of the DOK5 gene. This alteration results from a C to T substitution at nucleotide position 757, causing the arginine (R) at amino acid position 253 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
