Congenital insensitivity to pain with anhidrosis (CIPA) has two characteristic features: the inability to feel pain and temperature, and decreased or absent sweating (anhidrosis). -. Congenital Insensitivity to Pain with Anhidrosis, better known by its acronym CIPA, is a rare genetic disorder where the gene for creating the nerve cells that carry pain and temperature sensations is missing. All other sensory, motor, and autonomic functions are normal. Due to the fact congenital insensitivity to pain is an inherited condition and is not caused by external or other biological factors, there are no identified at-risk groups for the disorder, and the primary risk factor is a family history of the disorder. The genes and possible symptoms include the following. Researchers believe one reason individuals with congenital insensitivity to pain do not feel pain is due to an insurgence of endorphins to the brain. Congenital insensitivity to pain with anhidrosis (CIPA) is a rare genetic disease characterized by absence of reaction to noxious stimuli and anhidrosis. Although their parents are carriers of the gene mutation, because they only have one copy, they are typically healthy and do not present any symptoms or report any issues from the disorder. The goals of this overview on congenital insensitivity to pain (CIP) are the following. This condition is also known as hereditary sensory and autonomic neuropathy type IV. Congenital insensitivity to pain is caused by mutations in the SCN9A gene and, in rare cases, is caused by mutations in the PMRD12 gene. Congenital insensitivity to pain will allow a young child to unconsciously self-mutilate due to the failure of pain receptors to initiate a response in the brain and prevent these actions. Cognitive disorders are commonly coincident. Congenital insensitivity to pain is a very rare disorder that prevents an individual from feeling pain. Sodium channels transport positively charged sodium atoms (sodium ions) into cells and play a key role in a cell's ability to generate and transmit electrical signals. -, Bodner L, Woldenberg Y, Pinsk V, Levy J.

Congenital insensitivity to pain (CIP) is caused by extremely rare Mendelian genetic disorders. This is an extremely rare autosomal recessive disease and is often fatal. Endorphins also act as an analgesic or pain reliever due to the fact they interact with the opiate receptors in the brain. 2006;444:894–8. Insensitivity to pain means that the painful stimulus is not even perceived: a patient cannot describe the intensity or type of pain.

The primary cause for congenital insensitivity to pain is a mutation in the SCN9A gene, which controls one aspect of the sodium channel called NaV1.7. Patients with congenital insensitivity to pain seem not to perceive sensations of pain, that is, they have markedly impaired ability to perceive the type, intensity, and quality of painful stimuli. * HealthPrep does not provide medical advice, diagnosis or treatment. Physicians who suspect congenital insensitivity to pain is the cause of the patient's symptoms can confirm their diagnosis through genetic testing. Endorphins are a group of hormones produced in the brain that are responsible for the feelings of satisfaction, excitement, and pleasure. To provide an evaluation strategy to identify the genetic cause of congenital insensitivity to pain in a proband, Goal 4: Congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal recessive disorder of the nervous system which prevents the feeling of pain or temperature, and prevents a person from sweating.
