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):

• familial Mediterranean fever

  Inheritance: AD, AR, SD Classification: DEFINITIVE, SUPPORTIVE Submitted by: Orphanet, Myriad Women’s Health, ClinGen
• autosomal recessive familial Mediterranean fever

  Inheritance: AR Classification: DEFINITIVE Submitted by: G2P
• familial Mediterranean fever, autosomal dominant

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
