Congenital insensitivity to pain with anhidrosis

Congenital insensitivity to pain with anhidrosis (CIPA), also called hereditary sensory and autonomic neuropathy type IV, is an extremely rare inherited disorder of the nervous system which prevents the sensation of pain, heat, cold, or any real nerve-related sensations; however, patients can still feel pressure. CIPA is the fourth type of hereditary sensory and autonomic neuropathy (HSAN), known as HSAN IV.
