Genes affected

DOCK4 (HGNC:19192): (dedicator of cytokinesis 4) This gene is a member of the dedicator of cytokinesis (DOCK) family and encodes a protein with a DHR-1 (CZH-1) domain, a DHR-2 (CZH-2) domain and an SH3 domain. This membrane-associated, cytoplasmic protein functions as a guanine nucleotide exchange factor and is involved in regulation of adherens junctions between cells. Mutations in this gene have been associated with ovarian, prostate, glioma, and colorectal cancers. Alternatively spliced variants which encode different protein isoforms have been described, but only one has been fully characterized. [provided by RefSeq, Jul 2008]

The c.2935A>G (p.I979V) alteration is located in exon 28 (coding exon 28) of the DOCK4 gene. This alteration results from a A to G substitution at nucleotide position 2935, causing the isoleucine (I) at amino acid position 979 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
