Abstrakt

Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is a periodic fever syndrome inherited in an autosomal dominant fashion. It stems from mutations in the TNFRSF1A (accession number: NM_001065) gene expressing the receptor for tumor necrosis factor α. A patient with TRAPS may present with prolonged episodes of fever attacks, abdominal pain, severe myalgia, and painful erythema on the trunk or extremities. Here, we report an 8-year-old boy with febrile attacks occurring every 1-2months and continuing for 3-4days. The patient experienced 40°C-fever attacks without chills. Approximately 80% of fever attacks were accompanied by abdominal manifestations. Direct sequencing analysis was used to assess the genomic DNA of the patient, and a heterozygous R426L mutation in exon 10 of the TNFRSF1A gene in an autosomal dominant inheritance fashion was identified. Further genetic analyses were also carried out on his parents. Due to the fact that the mutation was not inherited from the parents, it was likely that R426L was a de novo and novel mutation in the TNFRSF1A gene, which can trigger TRAPS or TRAPS-like symptoms.
