Genes affected

CCL8 (HGNC:10635): (C-C motif chemokine ligand 8) This antimicrobial gene is one of several chemokine genes clustered on the q-arm of chromosome 17. Chemokines form a superfamily of secreted proteins involved in immunoregulatory and inflammatory processes. The superfamily is divided into four subfamilies based on the arrangement of N-terminal cysteine residues of the mature peptide. This chemokine is a member of the CC subfamily which is characterized by two adjacent cysteine residues. This cytokine displays chemotactic activity for monocytes, lymphocytes, basophils and eosinophils. By recruiting leukocytes to sites of inflammation this cytokine may contribute to tumor-associated leukocyte infiltration and to the antiviral state against HIV infection.

Ambry Genetics

Sep 22, 2022

The c.56C>T (p.P19L) alteration is located in exon 1 (coding exon 1) of the CCL8 gene. This alteration results from a C to T substitution at nucleotide position 56, causing the proline (P) at amino acid position 19 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
