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.

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 1488 of the DOCK7 protein (p.Thr1488Met). This variant is present in population databases (rs200226943, gnomAD 0.08%). This missense change has been observed in individual(s) with autism spectrum disorder (PMID: 25363768). ClinVar contains an entry for this variant (Variation ID: 541906). 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. 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. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.4397C>T (p.T1466M) alteration is located in exon 35 (coding exon 35) of the DOCK7 gene. This alteration results from a C to T substitution at nucleotide position 4397, causing the threonine (T) at amino acid position 1466 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
