What are the causes of Blau Syndrome?

Blau syndrome results from mutations in the NOD2 gene. The protein produced from this gene helps defend the body from foreign invaders, such as viruses and bacteria, by playing several essential roles in the immune response, including inflammatory reactions. An inflammatory reaction occurs when the immune system sends signaling molecules and white blood cells to a site of injury or disease to fight microbial invaders and facilitate tissue repair.

How prevalent is Blau Syndrome?

Blau syndrome is a very rare disorder. It is estimated to affect fewer than 1 in 1 million children worldwide.

Is Blau Syndrome an inherited disorder?

Blau syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most affected individuals have one parent with the condition.
