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

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.056805104).
BS2
High Homozygotes in GnomAdExome4 at 6 AR,AD,SD geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
