What is the disease CIPA?
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.
How is CIPA diagnosed?
The most definitive diagnostic test for CIPA is a genetic test, which can be done before birth or during childhood or adulthood. There is a known genetic abnormality that identifies CIPA, and it is called the human TRKA (NTRKI) gene located on chromosome 1 (1q21-q22).

What causes CIPA disease?
CIPA is caused by mutations in the NTRK1 gene , which gives the body instructions to make a protein that is important for the development and survival of nerve cells – especially those that carry information about pain, temperature, and touch (sensory neurons).
Can CIPA patients feel?
Congenital insensitivity to pain is a rare disorder, first described in 1932 by Dearborn as Congenital pure analgesia. Congenital insensitivity to pain and anhydrosis (CIPA) is a very rare and extremely dangerous condition. People with CIPA cannot feel pain [1].
How rare is CIPA disease?
Congenital insensitivity to pain and anhidrosis (CIPA) or HSAN type IV is an extremely rare autosomal recessive disorder initially described by Swanson in 1963 (2). The incidence of this disorder has been estimated to be 1 in 25, 000 population (3).
Can CIPA patients feel pressure?
CIPA is characterized by loss of pain and thermal sensation accompanied by mental distress. Other sensory modalities such as touch, pressure, and vibration are not affected.
Who is Ashlyn Blocker?
Ashlyn Blocker is a young girl who has a rare genetic disease called CIP which stands for congenital insensitivity to pain. In other words, Ashlyn feels no pain. She has the inability to sense extreme temperatures of hot and cold.
What is the difference between CIP and CIPA?
CIP is divided into two types: with anhidrosis (the inability to sweat) and without anhidrosis. Congenital insensitivity to pain with anhidrosis (CIPA) is the first human genetic disorder for which the molecular basis of CIP has been identified.
How many cases of CIPA are there?
CIPA is a very rare disease; there are only around 60 documented cases in the United States and around 300 worldwide (3). Since it is a genetic disease, CIPA is more likely to occur in homogeneous societies.
What is the mortality rate of CIPA?
The mortality rate in this study group was 7.3%. Epidemiological data of CIPA patients in this study.
What body systems does CIPA affect?
Congenital insensitivity to pain and anhidrosis (CIPA) is a rare disorder affecting autonomic nervous system, and therefore has been described as Hereditary Sensory and Autonomic Neuropathies (HSAN).
Can you lose the ability to feel pain?
Loss of sensation means that you can’t feel pain, heat, or cold. This can happen in one or more parts of your body. Loss of sensation can be caused by a complication of diabetes called peripheral neuropathy.
What’s the worst pain a human can endure?
The full list, in no particular order, is as follows:
- Shingles.
- Cluster headaches.
- Frozen shoulder.
- Broken bones.
- Complex regional pain syndrome (CRPS)
- Heart attack.
- Slipped disc.
- Sickle cell disease.
What is the disorder where you can’t feel emotions?
Alexithymia is not a condition in its own right, but rather an inability to identify and describe emotions. People with alexithymia have difficulties recognizing and communicating their own emotions, and they also struggle to recognize and respond to emotions in others.
Is CIPA a disability?
Intellectual disability. Most individuals with NTRK1-CIPA have varying degrees of intellectual disability and show characteristic behaviors [Indo 2002, Indo 2018]. Affected individuals show defects in conceptual thinking, abstract reasoning, and social behavior, as well as moderate to severe emotional disturbance.
Can CIPA patients feel cold?
Hereditary sensory and autonomic neuropathy type IV (HSAN4 or HSAN IV) is a rare genetic disorder that usually begins in infancy and is characterized by an inability to feel pain and an inability to sweat (anhidrosis). Affected individuals also cannot feel temperature and cannot distinguish between hot and cold.
