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.

Submissions by phenotype

Developmental and epileptic encephalopathy, 23 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 07, 2023This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1358 of the DOCK7 protein (p.Arg1358Gln). This variant is present in population databases (rs150781290, gnomAD 0.08%). 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: 576166). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DOCK7 protein function with a negative predictive value of 80%. 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. -

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2023The c.3980G>A (p.R1327Q) alteration is located in exon 31 (coding exon 31) of the DOCK7 gene. This alteration results from a G to A substitution at nucleotide position 3980, causing the arginine (R) at amino acid position 1327 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
