Genes affected

DOCK1 (HGNC:2987): (dedicator of cytokinesis 1) This gene encodes a member of the dedicator of cytokinesis protein family. Dedicator of cytokinesis proteins act as guanine nucleotide exchange factors for small Rho family G proteins. The encoded protein regulates the small GTPase Rac, thereby influencing several biological processes, including phagocytosis and cell migration. Overexpression of this gene has also been associated with certain cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Collection Method: clinical testing

The c.286C>G (p.L96V) alteration is located in exon 5 (coding exon 5) of the DOCK1 gene. This alteration results from a C to G substitution at nucleotide position 286, causing the leucine (L) at amino acid position 96 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
