Genes affected

MEFV (HGNC:6998): (MEFV innate immunity regulator, pyrin) This gene encodes a protein, also known as pyrin or marenostrin, that is an important modulator of innate immunity. Mutations in this gene are associated with Mediterranean fever, a hereditary periodic fever syndrome. [provided by RefSeq, Jul 2008]
