What is it?
Why don't they sweat?
Can you imagine what it is truly like to be unable to feel pain?
- Eccrine glands are sweat glands located in your epidermis all over your body.
- Because the nerve fibers are not present in the epidermis or sweat glands, there is no way for the brain to communicate to the body that it is overheating.
- Therefore, it is common for individuals with CIPA to have fevers from simply being in hot weather.

What causes this condition?
Genetics
- CIPA is part of a group of disorders called HSAN, which stands for hereditary sensory and autonomic neuropathy. Basically, disorders that cause trouble in perceiving pain and temperature.
- CIPA is HSAN type IV, meaning it is the most severe of the HSAN disorders, and the only condition of its kind that causes an inability to sweat.
- Congenital Analgesia is an autosomal recessive disorder.
- This means it can only be passed down if both an individual's parents are carriers of a mutated NTRK1 gene, which is responsible for nerve growth.
