Genes affected

CXCL5 (HGNC:10642): (C-X-C motif chemokine ligand 5) This gene encodes a protein that is a member of the CXC subfamily of chemokines. Chemokines, which recruit and activate leukocytes, are classified by function (inflammatory or homeostatic) or by structure. This protein is proposed to bind the G-protein coupled receptor chemokine (C-X-C motif) receptor 2 to recruit neutrophils, to promote angiogenesis and to remodel connective tissues. This protein is thought to play a role in cancer cell proliferation, migration, and invasion. [provided by RefSeq, May 2013]

The c.23C>T (p.A8V) alteration is located in exon 1 (coding exon 1) of the CXCL5 gene. This alteration results from a C to T substitution at nucleotide position 23, causing the alanine (A) at amino acid position 8 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
