Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000083740 SCV000696057 pathogenic Familial Mediterranean fever 2016-06-13 criteria provided, single submitter clinical testing Variant summary: The MEFV c.2081_2083delTGA (p.Met694del) variant involves an in-frame deletion of three nucleotides. One in silico tool predicts a benign outcome for this variant. The variant is absent in 121410 control chromosomes while it was reported in several FMF patients in heterozygosity indicating a dominant inheritance. Taken together, this variant is classified as pathogenic.

This variant is also reported in ClinVar (Variation ID: 2556), but is only observed on two alleles in the Genome Aggregation Database, indicating it is not a common polymorphism. This variant deletes a single methionine residue leaving the rest of the protein in-frame. Considering available information, this variant is classified as pathogenic. References: Belmahi L et al.

Invitae RCV000083740 SCV001491922 uncertain significance Familial Mediterranean fever 2022-08-19 criteria provided, single submitter clinical testing This variant, c.2081_2083del, results in the deletion of 1 amino acid(s) of the MEFV protein (p.Met694del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs104895091, gnomAD 0.002%). This variant has been observed in individual(s) with Familial Mediterranean Fever (PMID: 10024914, 10787449, 19479870, 21246368, 29047407). ClinVar contains an entry for this variant (Variation ID: 2556). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this variant affects MEFV function (PMID: 33733382). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
