Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP2

The NM_001367561.1(DOCK7):​c.3446C>A​(p.Pro1149His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 32)
• Consequence: DOCK7 NM_001367561.1 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 9.92

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

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.
