Hyper-IgD and periodic fever syndrome (HIDS) due to compound heterozygosity for G336S and V377I in a 44-year-old patient with a 27-year history of fever.

Hereditary autoinflammatory syndromes are a rare, but notable cause of fever of unknown origin. During the last few years, the knowledge of the genetic background has significantly increased. Here, we report a novel pathogenic mutation in the MVK gene as the cause of fever in a 44-year-old male patient with a history of fever over a period of 27 years. 2016 BMJ Publishing Group Ltd.
