What is Deficiency of Interleukin-1 Receptor Antagonist (DIRA)?
DIRA is an autoinflammatory disease first reported in 2009. People with DIRA lack a protein called interleukin-1 receptor antagonist (IL-1Ra), which helps to regulate inflammation. DIRA causes life-threatening systemic inflammation with skin and bone involvement. DIRA is a genetic disorder inherited in an autosomal recessive manner, meaning that a mutation in both copies of a gene is needed to cause the disease.
DIRA is a disease with fewer than 50 patients worldwide. Cases have been identified in families originating in Puerto Rico, Newfoundland (Canada), The Netherlands, Palestine/Lebanon, Germany, Turkey, India, and Brazil.
Signs of DIRA in Newborns
DIRA starts causing symptoms that are detected at birth or within days of birth due to inflammatory changes in the skin or bone. Common symptoms of DIRA include fetal distress, rashes that may resemble psoriasis, mouth lesions, joint swelling, painful movement, liver and spleen enlargement, and sore eyes.
