Genes affected

CRK (HGNC:2362): (CRK proto-oncogene, adaptor protein) This gene encodes a member of an adapter protein family that binds to several tyrosine-phosphorylated proteins. The product of this gene has several SH2 and SH3 domains (src-homology domains) and is involved in several signaling pathways, recruiting cytoplasmic proteins in the vicinity of tyrosine kinase through SH2-phosphotyrosine interaction. The N-terminal SH2 domain of this protein functions as a positive regulator of transformation whereas the C-terminal SH3 domain functions as a negative regulator of transformation. Two alternative transcripts encoding different isoforms with distinct biological activity have been described. [provided by RefSeq, Jul 2008]

The c.848G>A (p.R283Q) alteration is located in exon 3 (coding exon 3) of the CRK gene. This alteration results from a G to A substitution at nucleotide position 848, causing the arginine (R) at amino acid position 283 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
