Genes affected

DOCK7 (HGNC:19190): (dedicator of cytokinesis 7) The protein encoded by this gene is a guanine nucleotide exchange factor (GEF) that plays a role in axon formation and neuronal polarization. The encoded protein displays GEF activity toward RAC1 and RAC3 Rho small GTPases but not toward CDC42. Several transcript variants encoding different isoforms have been found for this gene.

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 07, 2022	This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 431 of the DOCK7 protein (p.Gly431Ala). This variant is present in population databases (rs201785444, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with DOCK7-related conditions. ClinVar contains an entry for this variant (Variation ID: 578368). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Likely benign, criteria provided, single submitter	clinical testing	3billion	Sep 20, 2024	The homozygous variant was found in patients diagnosed with another variant in a different gene, with no symptoms related to the gene containing the homozygous variant. -

The c.1292G>C (p.G431A) alteration is located in exon 12 (coding exon 12) of the DOCK7 gene. This alteration results from a G to C substitution at nucleotide position 1292, causing the glycine (G) at amino acid position 431 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
