Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 3P and 9B. PM2PP2BP4_StrongBP6BS1

The NM_001367561.1(DOCK7):c.3935C>T(p.Thr1312Met) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.000229 in 1,607,520 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/23 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. T1312T) has been classified as Likely pathogenic.

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.
