Genes affected

NCK2 (HGNC:7665): (NCK adaptor protein 2) This gene encodes a member of the NCK family of adaptor proteins. The protein contains three SH3 domains and one SH2 domain. The protein has no known catalytic function but has been shown to bind and recruit various proteins involved in the regulation of receptor protein tyrosine kinases. It is through these regulatory activities that this protein is believed to be involved in cytoskeletal reorganization. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

The c.832G>A (p.G278R) alteration is located in exon 1 (coding exon 1) of the NCK2 gene. This alteration results from a G to A substitution at nucleotide position 832, causing the glycine (G) at amino acid position 278 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
