Genes affected

CXCR3 (HGNC:4540): (C-X-C motif chemokine receptor 3) This gene encodes a G protein-coupled receptor with selectivity for three chemokines, termed CXCL9/Mig (monokine induced by interferon-g), CXCL10/IP10 (interferon-g-inducible 10 kDa protein) and CXCL11/I-TAC (interferon-inducible T cell a-chemoattractant). Binding of chemokines to this protein induces cellular responses that are involved in leukocyte traffic, most notably integrin activation, cytoskeletal changes and chemotactic migration. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. One of the isoforms (CXCR3-B) shows high affinity binding to chemokine, CXCL4/PF4 (PMID:12782716).

Feb 28, 2023

The c.79A>G (p.K27E) alteration is located in exon 2 (coding exon 1) of the CXCR3 gene. This alteration results from a A to G substitution at nucleotide position 79, causing the lysine (K) at amino acid position 27 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
