The MEFV c.549G>A;p.Pro183Pro (rs587781035) variant has not been described in the medical literature, but is listed in the ClinVar database as benign (Variation ID: 138207). The variant is listed in the Genome Aggregation Database as a rare variant (10/184110 alleles). This is a silent variant, the nucleotide at this position is not well conserved across species, and computational algorithms (SpliceSiteFinder-like, MaxEntScan, NNSplice, GeneSplicer, Human Splicing Finder) predict this variant does not significantly alter splicing. Additionally, this variant is inconsistent with the pathogenic mechanism of familial Mediterranean fever. Although this variant has been described in an individual with ulcerative colitis (see link below), this variant is classified as likely benign.
