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]

Feb 16, 2023

The c.149C>T (p.P50L) alteration is located in exon 3 (coding exon 2) of the CCR6 gene. This alteration results from a C to T substitution at nucleotide position 149, causing the proline (P) at amino acid position 50 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
