Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_StrongBP6BS2_Supporting

The NM_000243.3(MEFV):​c.1459G>C​(p.Val487Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000408 in 1,614,190 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V487M) has been classified as Likely benign.

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 -6 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0031388104).
BP6
Variant 16-3247144-C-G is Benign according to our data. Variant chr16-3247144-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 378132.
BS2
High Homozygotes in GnomAd4 at 3 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.
