OMIM : ⁵⁸ Blau syndrome is characterized by the triad of granulomatous arthritis, uveitis, and dermatitis. First described in 1985, it was considered to be distinct from sarcoidosis due to the early age of onset and autosomal dominant inheritance pattern. Published reports of sporadic cases of children with 'early-onset sarcoidosis' (EOS) with granulomatous involvement of different organs, primarily affecting joints, eyes, and skin, were suspected to represent the same disorder because the patients' characteristics were nearly identical. Subsequently, identical NOD2 mutations were identified in patients with Blau syndrome as well as in patients diagnosed with EOS, confirming earlier suspicions that they represented the same disease (summary by Borzutzky et al., 2010). Unlike older children diagnosed with sarcoidosis, these patients have no apparent pulmonary involvement; however, the disease is progressive and may result in severe complications such as blindness and/or joint destruction (Shetty and Gedalia, 1998).

MalaCards based summary : Blau Syndrome, also known as sarcoidosis, early-onset, is related to arthritis and sarcoidosis 1. An important gene associated with Blau Syndrome is NOD2 (Nucleotide Binding Oligomerization Domain Containing 2), and among its related pathways/superpathways are NOD-like receptor signaling pathway and Innate Immune System. Affiliated tissues include skin, eye and liver, and related phenotypes are joint swelling and arthralgia

Disease Ontology : ¹² An autosomal dominant disease characterized by familial granulomatous arthritis, uveitis and skin granulomas. It has material basis in mutations in the NOD2/CARD15 genes.

Genetics Home Reference : ²⁶ Blau syndrome is an inflammatory disorder that primarily affects the skin, joints, and eyes. Signs and symptoms begin in childhood, usually before age 4.

NIH Rare Diseases : ⁵⁴ Blau syndrome is a rare condition characterized mainly by skin rash, arthritis and uveitis. It has variable expressivity and usually affects preschool age children younger than four years of age. Characteristic findings include synovial effusions (fluid in the joints due to inflammation) and cysts, anterior uveitis (swelling and irritation of the uvea) and focal posterior synechiae (adhesion of the iris to the cornea). Permanent bending of the fingers and toes (camptodactyly) and other findings have also been reported. It is caused by mutations in the NOD2 gene and is inherited in an autosomal dominant manner. Blau syndrome and early-onset sarcoidosis have the same symptoms and genetic cause, but early-onset sarcoidosis is caused by de novo (new) mutations and occurs sporadically (in individuals with no history of the disorder in the family).

UniProtKB/Swiss-Prot : ⁷⁶ Blau syndrome: An autosomal dominant inflammatory disorder characterized by the formation of immune granulomas invading the skin, joints and eye. Other organs may be involved. Clinical manifestations are variable and include early-onset granulomatous arthritis, uveitis and skin rash. Blindness, joint destruction and visceral involvement have been reported in severe cases.
