The MEFV c.586G>T; p.Gly196Trp variant (rs104895179) is reported in the literature in several individuals with periodic fever or autoimmune syndromes (Cantarini 2012, Oztuzcu 2014 ). However, the variant has also been reported in at least one individual with an alternate molecular explanation for disease (Gunesacar 2014). The variant is reported in the ClinVar database (Variation ID: 97532) and in the African population with an allele frequency of 1.7% (350/20,178 alleles including 2 homozygotes) in the Genome Aggregation Database. The glycine at codon 196 is weakly conserved and computational analyses (SIFT: Damaging, PolyPhen-2: Benign) predict conflicting effects of this variant on protein structure/function. Although the allele frequency of this variant is higher than would be predicted for FMF, given the lack of clinical and functional data, the significance of the p.Gly196Trp variant is uncertain at this time.
