Genes affected

CCR6 (HGNC:1607): (C-C motif chemokine receptor 6) This gene encodes a member of the beta chemokine receptor family, which is predicted to be a seven transmembrane protein similar to G protein-coupled receptors. The gene is preferentially expressed by immature dendritic cells and memory T cells. The ligand of this receptor is macrophage inflammatory protein 3 alpha (MIP-3 alpha). This receptor has been shown to be important for B-lineage maturation and antigen-driven B-cell differentiation, and it may regulate the migration and recruitment of dentritic and T cells during inflammatory and immunological responses. Alternatively spliced transcript variants that encode the same protein have been described for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 03, 2023

The c.7G>A (p.G3R) alteration is located in exon 2 (coding exon 1) of the CCR6 gene. This alteration results from a G to A substitution at nucleotide position 7, causing the glycine (G) at amino acid position 3 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
