PG - 57-64 LID - 10.1080/09273948.2016.1185529 [doi] AB - PURPOSE: To describe the clinical and molecular implications of a novel mutation in the NOD2/CARD15 gene on a family and its seven affected members. METHODS: We reviewed the clinical presentations of family members who came to our center for refractory uveitis. Genetic testing and molecular testing was performed. RESULTS: All affected members had adult onset recurrent non-granulomatous panuveitis. The inheritance pattern suggested an autosomal dominant disease and genetic analysis identified a novel mutation in the NOD2 gene that converted amino acid 600 from glutamate to alanine (E600A). Transfection of the E600A NOD2 into human embryonic kidney-293 (HEK293) cells revealed constitutive activation and a reduced ability to respond to the NOD2 ligand, muramyl dipeptide (MDP) as compared with wild-type NOD2. CONCLUSIONS: The E600A mutation in the NOD2 gene may confer a higher penetrance of uveitis but a later onset of milder forms of non-ocular involvement.
