Is there genetic testing for congenital insensitivity to pain?
Diagnosis/testing. The diagnosis of NTRK1-CIPA is established in a proband with suggestive clinical findings and biallelic pathogenic variants in NTRK1 identified by molecular genetic testing.
Is CIPA genetic?
CIPA is a hereditary disease. It is autosomal recessive, which means that any person who has CIPA must inherit the gene from both parents. 1 Typically, the parents of an affected child carry the gene but do not have the disease if they only inherited the gene from one parent.
What gene is responsible for CIPA?
The TRKA (NTRK1) gene located on chromosome 1 (1q21-q22), consists of 17 exons and spans at least 23 kb. TRKA encodes the receptor tyrosine kinase (RTK) for nerve growth factor (NGF) and is the gene responsible for CIPA.
What gene causes congenital insensitivity to pain?
Mutations in the SCN9A gene cause congenital insensitivity to pain. The SCN9A gene provides instructions for making one part (the alpha subunit) of a sodium channel called NaV1.
How do you get congenital insensitivity to pain?
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.
Is there treatment for congenital insensitivity to pain?
There is still no cure for CIPA. Treatment is aimed at controlling body temperature, preventing self-injury, and treating orthopedic problems, as soon as possible. It is very important to control the body temperature during surgery.
How long do kids with CIPA live?
CIPA is extremely dangerous, and in most cases the patient doesn’t live over age of 25. Although some of them can live a fairly normal life, they must constantly check for cuts, bruises, self-mutilations, and other possible unfelt injuries.
What is CEPA disease?
Congenital insensitivity to pain with anhidrosis (CIPA) has two characteristic features: the inability to feel pain and temperature, and decreased or absent sweating (anhidrosis). This condition is also known as hereditary sensory and autonomic neuropathy type IV.
Is there a cure for CIPA?
How is congenital insensitivity diagnosed?
Establishing the Clinical Diagnosis of Congenital Insensitivity to Pain. There are no consensus clinical diagnostic criteria for CIP. However, a diagnosis requires visible proof of lack of nociception in a conscious individual of normal intellectual ability.
What is genetic pain?
The notion of “genetic pain” or trauma – that actions in one person’s life can so mark their genes that their bodies literally adapt to the issue, and that is passed on to the next generation through their genetic code – is one that is a trendy topic in science.
How do you test for congenital insensitivity to pain?
What is hereditary insensitivity to pain with anhidrosis?
Hereditary insensitivity to pain with anhidrosis. Summary. Excerpted from the GeneReview: Congenital insensitivity to pain with anhidrosis (CIPA), also known as hereditary sensory and autonomic neuropathy type IV (HSAN IV), is characterized by insensitivity to pain, anhidrosis (the inability to sweat), and intellectual disability.
What is congenital insensitivity to pain with anhidrosis (CIPA)?
Congenital insensitivity to pain with anhidrosis (CIPA) also known as hereditary sensory and autonomic neuropathy type IV, is an inherited disease where there is an inability to feel pain and temperature, and decreased or absent sweating (anhidrosis).
What is congenital insensitivity to pain?
Congenital insensitivity to pain is an extremely rare phenotype and the exact proportion of individuals with pathogenic variants in each gene within the whole population is not known. Table 1.
What are the treatment and surveillance guidelines for congenital insensitivity to pain?
No consensus treatment or surveillance guidelines have been developed. Treatment is supportive and is best provided by specialists in pediatrics, orthopedics, dentistry, ophthalmology, and dermatology (see Congenital Insensitivity to Pain with Anhidrosis ). Table 4. Treatment w/an external fixator may → potentially serious infectious complications.
