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 variant has not been reported in the literature in individuals affected with DOCK7-related conditions. 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. 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. ClinVar contains an entry for this variant (Variation ID: 541907). This variant is present in population databases (rs570203355, gnomAD 0.02%), including at least one homozygous and/or hemizygous individual. This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 600 of the DOCK7 protein (p.Pro600Leu). -
