Genes affected

CXCL10 (HGNC:10637): (C-X-C motif chemokine ligand 10) This antimicrobial gene encodes a chemokine of the CXC subfamily and ligand for the receptor CXCR3. Binding of this protein to CXCR3 results in pleiotropic effects, including stimulation of monocytes, natural killer and T-cell migration, and modulation of adhesion molecule expression. This gene may also be a key regulator of the 'cytokine storm' immune response to SARS-CoV-2 infection. [provided by RefSeq, Sep 2020]

ART3 (HGNC:725): (ADP-ribosyltransferase 3 (inactive)) This gene encodes an arginine-specific ADP-ribosyltransferase. The encoded protein catalyzes a reversible reaction which modifies proteins by the addition or removal of ADP-ribose to an arginine residue to regulate the function of the modified protein. An ADP-ribosyltransferase pseudogene is located on chromosome 11. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

Nov 18, 2022

The c.158C>T (p.A53V) alteration is located in exon 2 (coding exon 2) of the CXCL10 gene. This alteration results from a C to T substitution at nucleotide position 158, causing the alanine (A) at amino acid position 53 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
