Genes affected

CCL4 (HGNC:10630): (C-C motif chemokine ligand 4) The protein encoded by this gene is a mitogen-inducible monokine and is one of the major HIV-suppressive factors produced by CD8+ T-cells. The encoded protein is secreted and has chemokinetic and inflammatory functions. [provided by RefSeq, Dec 2012]

The c.110C>G (p.S37C) alteration is located in exon 2 (coding exon 2) of the CCL4 gene. This alteration results from a C to G substitution at nucleotide position 110, causing the serine (S) at amino acid position 37 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
