Disease Profile

Familial cold autoinflammatory syndrome

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Summary

Familial cold autoinflammatory syndrome is a type of periodic fever syndrome. Signs and symptoms may include include an itchy or burning rash; fever; and joint pain which are triggered by exposure to cold temperatures. It is inherited in an autosomal dominant manner and can be caused by mutations in the NLRP3 or NLRP12 genes. Management of this condition involves avoiding exposure to cold temperatures and treatment with specific types of medications.[1][2]

Symptoms

Signs and symptoms of familial cold autoinflammatory syndrome may include rash, fever, and joint pain triggered by exposure to cold temperatures. The rash often begins on exposed arms and legs and extends to the remainder of the body. The rash may consist of red macules and plaques, hives (urticaria), and petechiae. The skin rash can cause burning or itching. Conjuctivitis during a fever episode is also common. Other symptoms can include swelling, muscle pain, profuse sweating, drowsiness, headache, extreme thirst, and nausea.[1]

Symptoms may begin anywhere between 10 minutes to 8 hours after cold exposure. Fever attacks may last a few hours up to three days. Most people with familial cold autoinflammatory syndrome experience their first fever attack within the first year of life, many within the first day of life. Episodes continue to occur throughout life.[1]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause

Familial cold autoinflammatory syndrome is caused by changes (mutations) in either one of two genes: NLRP3 or NLRP12. These genes normally provide instructions for making proteins involved in the immune system, helping to regulate the process of inflammation. Changes in these genes impair the body's mechanisms for controlling inflammation, resulting in the signs and symptoms of this condition. It remains unclear why episodes are triggered by cold exposure.[2]

Diagnosis

Familial cold autoinflammatory syndrome (FCAS) is primarily a clinical diagnosis, meaning that it is mostly based on the presence or absence of specific of signs and symptoms as well as family history.[3] Diagnostic criteria have been proposed in order to distinguish FCAS from acquired cold urticaria and other periodic fever disorders. The criteria include: recurring episodes of fever and rash that primarily follow cold exposures; autosomal dominant pattern of disease inheritance in a family; age of onset younger than 6 months; duration of most attacks less than 24 hours; conjunctivitis in association with attacks; and absence of deafness, swelling around the eyes, enlarged lymph nodes, and serositis.[1][3] Having four of six of the criteria strongly suggests a diagnosis of FCAS. A diagnosis of FCAS may also be confirmed in some affected individuals by genetic testing.[3]

Testing Resources

  • The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

    Treatment

    Individuals with familial cold autoinflammatory syndrome (FCAS) are generally advised to avoid exposure to cold temperatures. Bed rest, warmth and corticosteroids can be used to treat an acute attack.[4] Treatment may include the use of biologic agents (drugs derived from living material) which can control the symptoms of FCAS by blocking interleukin-1; they are called selective recombinant interleukin-1 receptor agonists. Examples of these agents are rilonacept, anakinra, and canakinumab.[5][4] These agents reportedly have a significant beneficial effect on quality of life for individuals with FCAS.[4]
