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

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.84).
BP6
Variant 16-3249599-C-T is Benign according to our data. Variant chr16-3249599-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 527806.
BP7
Synonymous conserved (PhyloP=-0.907 with no splicing effect.
BS2
High Homozygotes in GnomAdExome4 at 5 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.
