Summary Summary

Congenital insensitivity to pain is a condition, present from birth, that inhibits the ability to perceive physical pain. Affected individuals are unable to feel pain in any part of their body. Over time, this lack of pain awareness can lead to an accumulation of injuries and health issues that may affect life expectancy.^[1] Congenital insensitivity to pain is caused by mutations in the SCN9A gene and, in rare cases, is caused by mutations in the PMRD12 gene. It is inherited in an autosomal recessive pattern.^[1]^[2]^[3]

Congenital insensitivity to pain is considered a form of peripheral neuropathy because it affects the peripheral nervous system, which connects the brain and spinal cord to muscles and to cells that detect sensations such as touch, smell, and pain.^[1] It is part of a group known as hereditary sensory and autonomic neuropathies.

Symptoms Symptoms

Congenital insensitivity to pain is characterized by the inability to perceive physical pain. People with this condition can feel the difference between sharp and dull and hot and cold, but cannot sense, for example, that a hot beverage is burning their tongue. This condition, which is present from birth, can lead to an accumulation of wounds, bruises, broken bones, and other health issues that may go undetected over time and can lead to a reduction in life expectancy. Young children with congenital insensitivity to pain may have mouth or finger wounds due to self-biting and may also experience multiple burn-related injuries. Many people with this condition also have a complete loss of the sense of smell (anosmia).^[1] In cases of congenital insensitivity to pain caused by mutations in the PRDM12 gene, the patients have a normal sense of smell, predisposition to infections and a greater incidence of corneal abrasions due to a lack of tear production.^[3]

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.

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

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.

Find a Specialist Find a Specialist

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.
