Genes affected
NCKAP1 (HGNC:7666): (NCK associated protein 1) Contributes to small GTPase binding activity. Involved in Rac protein signal transduction; positive regulation of Arp2/3 complex-mediated actin nucleation; and positive regulation of lamellipodium assembly. Located in extracellular exosome and focal adhesion. Part of SCAR complex. [provided by Alliance of Genome Resources, Apr 2022]

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 28, 2023 | The c.2720A>G (p.D907G) alteration is located in exon 26 (coding exon 26) of the NCKAP1 gene. This alteration results from an A to G substitution at nucleotide position 2720, causing the aspartic acid (D) at amino acid position 907 to be replaced by a glycine (G). This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. This missense alteration is located in a region that has a low rate of benign missense variation (Lek, 2016; Firth, 2009). The in silico prediction for this alteration is inconclusive. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
