Periodic fever syndromes comprise a group of disorders characterized by attacks of seemingly unprovoked inflammation. The genetic causes of five hereditary autoinflammatory syndromes have been identified in the last few years: familial Mediterranean fever, the cryopyrinopathies [Muckle-Wells, chronic infantile neurological, cutaneous, articular syndrome (CINCA) and familial autoinflammatory syndromes], TNF-receptor associated periodic syndrome, cyclic neutropenia syndrome and periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome. The study of periodic fever syndromes has progressed from clinical characterization to genetic analysis and to the definition of the functional defects linking genes or domains to apoptotic proteins and signal transduction pathways. This new research opens the way for more specific treatment options with a further improvement in prognosis and outcome.

PFAPA is a periodic fever disease, of unknown etiology, characterized by aphthous stomatitis, pharyngitis and cervical adenitis. To inquire whether genes implicated in other auto-inflammatory diseases might be involved in its pathogenesis, predominant mutations in the genes causing familial Mediterranean fever, TNF receptor-associated periodic fever syndrome, Crohn's disease and Muckel-Wells syndrome were analyzed in PFAPA patients. Patients (n = 57) with PFAPA, according to previously published criteria were recruited, at the Meyer Children Hospital during 2006-2007. Clinical information was complemented during physicians-parents encounter. Predominant mutations in MEFV, TNF1rA, CARD15/NOD2 and NLRP3 genes were tested. Mean age at diagnosis was 30.64 +/- 16.4 months. Boys (n = 33; 58%) were diagnosed earlier than girls (n = 21; 42%) at 26.18 +/- 13.83 and 36.41 +/- 18.32 months, respectively (P = 0.05). Fifteen patients (27%) carried an MEFV mutation; two patients (3.6%) a CARD15 mutation, one patient (1.8%) a variance in TNF1rA and another had both an MEFV and a CARD15 mutation. Clinical symptoms were equally manifested in carriers and non-carriers. The high carrier rate of MEFV mutations in our PFAPA cases compares well with that of the general population in Israel. It is debated whether MEFV mutations, when mediated by the presence of additional modifiers, may expose a transient fever condition, namely PFAPA.
