Pyrin

This gene encodes a protein, also known as pyrin or marenostrin, that plays an important modulator in innate immunity. Mutations in this gene are causeautosomal recessive or dominant Mediterranean fever.

Interpretation

the group of disorders caused by mutations of the MEFV gene are called pyrin-associated autoinflammatory diseases. Recessive familial Mediterranean fever is caused by mutations in exon 10 that encodes the pyrin B30.2 domain. A great number of patient harbor only one mutation in that exon. The severe clinical cause may be aggravated by an additional mutation in exon 3 (p.Pro373Leu), exon 5 (p.His478Tyr) or exon 8 (p.Thr577/Ser/Asn/Ala).

A different phenotype, dominant acute febrile neutrophilic dermatosis, is caused by missense mutations of codons 242 and 244 in exon 2. These mutations alter phosphorilation dependent pyrin inhibition by the 14-3-3 protein.
