Genes affected

NCK1 (HGNC:7664): (NCK adaptor protein 1) The protein encoded by this gene is one of the signaling and transforming proteins containing Src homology 2 and 3 (SH2 and SH3) domains. It is located in the cytoplasm and is an adaptor protein involved in transducing signals from receptor tyrosine kinases to downstream signal recipients such as RAS. Alternatively spliced transcript variants encoding different isoforms have been found. [provided by RefSeq, Jun 2010]

The c.1061A>G (p.E354G) alteration is located in exon 4 (coding exon 3) of the NCK1 gene. This alteration results from a A to G substitution at nucleotide position 1061, causing the glutamic acid (E) at amino acid position 354 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
