A stop gain variant in TNFRSF4 (NM_003327.3:c.384C > A (p.Cys128*)) was present in two FMF cases, whereas missense variants in TNFRSF8 (NM_001243.4:c.1511G > A (p.Arg504Gln)) and TNFRSF9 (NM_003811.3:c.716G > A (p.Arg239Gln)) were present in single FMF case each. This evidence concerns the gene TNFRSF9 and familial Mediterranean fever.
