Investigation of the functional variant c.-169T > C of the Fc receptor-like 3 (FCRL3) gene in alopecia areata

A functional variant in the Fc receptor-like 3 (FCRL3) gene has been implicated in susceptibility to autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus and autoimmune thyroid disease. Investigating a large case-control sample of patients with alopecia areata (AA), we found no evidence for the involvement of FCRL3 in susceptibility to AA.
