Genes affected

HCK (HGNC:4840): (HCK proto-oncogene, Src family tyrosine kinase) The protein encoded by this gene is a member of the Src family of tyrosine kinases. This protein is primarily hemopoietic, particularly in cells of the myeloid and B-lymphoid lineages. It may help couple the Fc receptor to the activation of the respiratory burst. In addition, it may play a role in neutrophil migration and in the degranulation of neutrophils. Multiple isoforms with different subcellular distributions are produced due to both alternative splicing and the use of alternative translation initiation codons, including a non-AUG (CUG) codon.

Collection Method: clinical testing

The c.274A>G (p.I92V) alteration is located in exon 4 (coding exon 4) of the HCK gene. This alteration results from a A to G substitution at nucleotide position 274, causing the isoleucine (I) at amino acid position 92 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
