Many interleukins and their receptors sequences were also found to be altered in FMF patients like IL17RB (NM_018725.3:c.529G > A (p.Gly177Arg)), IL17RD (NM_017563.4:c.1696C > T (p.Pro566Ser)), IL1R2 (NM_004633.3:c.932T > C (p.Ile311Thr)), IL20 (NC_000001.10(NM_018724.3):c.225 + 1G>T), IL12A (NM_000882.3:c.631G > A (p.Val211Met)) and IL1A (NM_000575.4:c.526G > C (p.Asp176His)), with IL17RB (NM_018725.3:c.529G > A (p.Gly177Arg)) and IL1R2 (NM_004633.3:c.932T > C (p.Ile311Thr)) variants present in three patients each, and the remaining other variants present in one case each. The gene discussed is IL20; the disease is familial Mediterranean fever.
