Genes affected

CCL17 (HGNC:10615): (C-C motif chemokine ligand 17) This antimicrobial gene is one of several Cys-Cys (CC) cytokine genes clustered on the q arm of chromosome 16. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene displays chemotactic activity for T lymphocytes, but not monocytes or granulocytes. The product of this gene binds to chemokine receptors CCR4 and CCR8. This chemokine plays important roles in T cell development in thymus as well as in trafficking and activation of mature T cells. [provided by RefSeq, Sep 2014]

Ambry Genetics

Nov 30, 2021

The c.119G>A (p.G40E) alteration is located in exon 3 (coding exon 2) of the CCL17 gene. This alteration results from a G to A substitution at nucleotide position 119, causing the glycine (G) at amino acid position 40 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
