Muckle-Wells Syndrome Overview
Learn About Muckle-Wells Syndrome
Cryopyrin-associated periodic syndromes (CAPS) are a group of conditions that have overlapping signs and symptoms and the same genetic cause. The group includes three conditions known as familial cold autoinflammatory syndrome type 1 (FCAS1), Muckle-Wells syndrome (MWS), and neonatal-onset multisystem inflammatory disorder (NOMID). These conditions were once thought to be distinct disorders but are now considered to be part of the same condition spectrum. FCAS1 is the least severe form of CAPS, MWS is intermediate in severity, and NOMID is the most severe form.
CAPS are caused by variants (also known as mutations) in the NLRP3 gene. The NLRP3 gene provides instructions for making a protein called cryopyrin. Cryopyrin is a member of a family of proteins called intracellular "NOD-like" receptor (NLR) proteins. These proteins are involved in the immune system, helping to regulate the process of inflammation. Inflammation occurs when the immune system sends signaling molecules and white blood cells to a site of injury or disease to fight foreign invaders and help repair damaged tissues. After this has been accomplished, the body stops (inhibits) the inflammatory response to prevent damage to its own cells and tissues. Cryopyrin is involved in the assembly of a molecular complex called an inflammasome, which helps trigger the inflammatory process.
CAPS are rare, with an estimated prevalence of 2 to 5 per million individuals, collectively. However, it is thought that the conditions are underdiagnosed since the features of CAPS are similar to other more common conditions.
CAPS are usually inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. People with the condition are born with one altered copy of the NLRP3 gene in each cell. In most cases, the altered gene is inherited from an affected parent. The remaining cases are a result of new variants in the NLRP3 gene and occur in people with no history of the disorder in their family.

Background: Anakinra is a drug used to treat people with certain diseases that affect their immune systems. Sometimes anakinra can cause proteins under the skin to clump together. These clumps are called amyloidosis; they can spread to other organs. The only way to diagnose amyloidosis is to remove a piece of tissue (biopsy). Researchers want to find a way to locate amyloidosis in internal organs using positr...
Background: Some diseases cause chronic inflammation with intermittent flares in the body. These are called autoinflammatory diseases. They can cause fevers, rashes, ulcers, and other problems. Researchers want to learn more about the causes and effects of these diseases. They hope this will improve how the disease is managed in the future.
