Abstract

Tumour necrosis factor receptor-associated periodic syndrome (TRAPS) results from point mutations in the extracellular domain of TNF receptor 1 (TNFRSF1A), but the effects of the mutations are controversial. This study shows that reduced NF-κB signalling is a feature of four TRAPS mutations. Reduced signalling correlates with reduced surface expression, measured by flow cytometry and microscopy. This suggests that correct formation of the extracellular domain of TNFRSF1A is important for localisation and receptor function. Importantly, our data provides a mechanism for the reduced TNFRSF1 signalling observed in a patient cell line.
