Abstract
Significance In this report we identify genetic susceptibility variants for periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome, the most common periodic fever syndrome in children. PFAPA shares risk loci at IL12A , STAT4, IL10 , and CCR1-CCR3 with Behçet’s disease and recurrent aphthous stomatitis, defining a family of Behçet’s spectrum disorders. Differential HLA associations along this spectrum may determine where individual phenotypes fall among the Behçet’s spectrum disorders.
