Variant Summary: The MEFV variant, c.586G>T (p.Gly196Trp), causes a missense change involving a non-conserved nucleotide with 2/4 in silico tools (SNPs&GO not captured here due to low reliability index value) predict a benign outcome, although these predictions have yet to be functionally assessed. The variant was observed in the large and broad cohorts of the ExAC project at an allele frequency of 0.20%, predominantly observed in the African subpopulation at a frequency of 2.4%. This frequency slightly exceeds the maximal expected allele frequency for a pathogenic variant in MEFV (2.2%), suggesting this is a benign polymorphism found primarily in population(s) of African origin. The variant has been reported in the literature in at least 2 FMF patients, one of whom also had a common pathogenic mutation in the homozygous state (c.2082G>A, M694I; Gunesacar_2014), suggesting the variant of interest was not the causitive mutation in this individual. The variant has also been reported in atypical FMF patients and a Systemic Juvenile Idiopathic Arthritis patient, however the variant was the only detected variant in these patients. In addition, one reputable clinical lab has classified the variant as "benign", without evidence to independently evaluate. Taken together, this variant has been classified as a variant of uncertain significance, possibly benign variant, until additional information becomes available.
