Genes affected

DOK2 (HGNC:2991): (docking protein 2) The protein encoded by this gene is constitutively tyrosine phosphorylated in hematopoietic progenitors isolated from chronic myelogenous leukemia (CML) patients in the chronic phase. It may be a critical substrate for p210(bcr/abl), a chimeric protein whose presence is associated with CML. This encoded protein binds p120 (RasGAP) from CML cells. [provided by RefSeq, Jul 2008]

The c.887A>G (p.E296G) alteration is located in exon 5 (coding exon 5) of the DOK2 gene. This alteration results from a A to G substitution at nucleotide position 887, causing the glutamic acid (E) at amino acid position 296 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
