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.

The c.145G>T (p.V49L) alteration is located in exon 3 (coding exon 3) of the DOCK7 gene. This alteration results from a G to T substitution at nucleotide position 145, causing the valine (V) at amino acid position 49 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
