Genes affected

DOCK5 (HGNC:23476): (dedicator of cytokinesis 5) This gene encodes a member of the dedicator of cytokinesis protein family. Members of this family act as guanine nucleotide exchange factors for small Rho family G proteins. The protein encoded by this gene is thought to associate with adaptors CRK and CRKL, and function in regulation of intestinal epithelial cell spreading and migration on collagen IV. Similar proteins in mouse and zebrafish also function in myoblast fusion. [provided by RefSeq, Oct 2016]

The c.497G>A (p.R166Q) alteration is located in exon 7 (coding exon 7) of the DOCK5 gene. This alteration results from a G to A substitution at nucleotide position 497, causing the arginine (R) at amino acid position 166 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
