Both categories are associated with uveitis, but the most commonly associated SAIDs comprise cryopyrin-associated periodic syndromes (CAPS), familial Mediterranean fever (FMF), TNF receptor associated periodic syndrome (TRAPS), mevalonate kinase deficiency (MVKD), Blau's syndrome (BS), deficiency of adenosine deaminase 2 (DADA2) and haploinsufficiency of A20 (HA20), Aicardi-Goutieres syndrome (AGS), and chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) (116, 119). Here, ADA2 is linked to familial Mediterranean fever.
