Genes affected

CCR4 (HGNC:1605): (C-C motif chemokine receptor 4) The protein encoded by this gene belongs to the G-protein-coupled receptor family . It is a receptor for the CC chemokine - MIP-1, RANTES, TARC and MCP-1. Chemokines are a group of small polypeptide, structurally related molecules that regulate cell trafficking of various types of leukocytes. The chemokines also play fundamental roles in the development, homeostasis, and function of the immune system, and they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis.

The c.688C>A (p.Q230K) alteration is located in exon 2 (coding exon 1) of the CCR4 gene. This alteration results from a C to A substitution at nucleotide position 688, causing the glutamine (Q) at amino acid position 230 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
