CCL27
Chr 9C-C motif chemokine ligand 27
Also known as: ALP, CTACK, CTAK, ESKINE, ILC, PESKY, SCYA27
The protein is a chemokine that attracts skin-associated memory T lymphocytes to cutaneous sites by binding to the CCR10 receptor. Mutations in CCL27 cause autosomal dominant atopic dermatitis-like eruption, affecting the skin and immune system. The gene is not highly constrained against loss-of-function variants, suggesting tolerance to functional disruption.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
The highest-scoring mechanism for this gene is dominant-negative.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
