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]
MEFV Gene-Disease associations (from GenCC):
  • autosomal recessive familial Mediterranean fever
    Inheritance: AR Classification: DEFINITIVE Submitted by: G2P
  • familial Mediterranean fever
    Inheritance: AR, SD, AD Classification: DEFINITIVE, SUPPORTIVE Submitted by: Myriad Women’s Health, ClinGen, Orphanet
  • familial Mediterranean fever, autosomal dominant
