Genes affected

CCL27 (HGNC:10626): (C-C motif chemokine ligand 27) This gene is one of several CC cytokine genes clustered on the p-arm of chromosome 9. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The protein encoded by this gene is chemotactic for skin-associated memory T lymphocytes. This cytokine may also play a role in mediating homing of lymphocytes to cutaneous sites. It specifically binds to chemokine receptor 10 (CCR10). Studies of a similar murine protein indicate that these protein-receptor interactions have a pivotal role in T cell-mediated skin inflammation.

The c.154C>A (p.Q52K) alteration is located in exon 2 (coding exon 2) of the CCL27 gene. This alteration results from a C to A substitution at nucleotide position 154, causing the glutamine (Q) at amino acid position 52 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
