The variant received 2 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_Moderate

The NM_000243.3(MEFV):c.2080A>T (p.Met694Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.00000137 (AC=2) in the gnomAD database across 1,461,882 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000000899. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★). A different missense at the same amino acid position has been reported as Pathogenic/Likely Pathogenic in ClinVar: p.M694V: Pathogenic (ClinVar VariationId 449657, 1 star) Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.M694K: Uncertain_significance (ClinVar VariationId 803180, 1 star); p.M694L: Uncertain_significance (ClinVar VariationId 3689508, 1 star); p.M694dup: Uncertain_significance (ClinVar VariationId 1785563, 1 star) This exact variant is curated in the UniProt human variants database as Uncertain Significance, associated with Familial mediterranean fever (fmf).

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]
