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.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DOCK7. . Gene score misZ 3.4194 (greater than the threshold 3.09). Trascript score misZ 3.8677 (greater than threshold 3.09). GenCC has associacion of gene with developmental and epileptic encephalopathy, 23, developmental and epileptic encephalopathy.

Submissions by phenotype

Developmental and epileptic encephalopathy, 23 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 12, 2022This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 254 of the DOCK7 protein (p.Pro254Ala). This variant is present in population databases (rs199803893, gnomAD 0.004%). 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: 475170). 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. -
