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

Our verdict: Benign. The variant received -11 ACMG points.

• BP4: Computational evidence support a benign effect (REVEL=0.29).
• BP6: Variant 1-62455318-C-A is Benign according to our data. Variant chr1-62455318-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 1327699.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00298 (454/152238) while in subpopulation AFR AF = 0.0104 (430/41546). AF 95% confidence interval is 0.00954. There are 0 homozygotes in GnomAd4. There are 214 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 4 AR gene
