Genes affected

CRKL (HGNC:2363): (CRK like proto-oncogene, adaptor protein) This gene encodes a protein kinase containing SH2 and SH3 (src homology) domains which has been shown to activate the RAS and JUN kinase signaling pathways and transform fibroblasts in a RAS-dependent fashion. It is a substrate of the BCR-ABL tyrosine kinase, plays a role in fibroblast transformation by BCR-ABL, and may be oncogenic.[provided by RefSeq, Jan 2009]

The c.351C>A (p.N117K) alteration is located in exon 2 (coding exon 2) of the CRKL gene. This alteration results from a C to A substitution at nucleotide position 351, causing the asparagine (N) at amino acid position 117 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
