SIR, Early-onset sarcoidosis (EOS) and Blau syndrome (BS) are rare multi-organ granulomatous inflammatory disorders clinically characterized by the distinct triad of skin, joint and eye lesions without any apparent cardio-pulmonary involvement [1]. Gain-of-function mutations in CARD15 (NM_022162
[GenBank]
) cause EOS and/or BS (EOS/BS) [2–4], but not the development of adult-type sarcoidosis [5,6]. We identified a novel heterozygous gain-of-function mutation, G481D, in CARD15 from a patient with EOS, who was suffering from recurrent
