A Kashmiri family with 3 members affected by a congenital sensory and autonomic neuropathy and corneal opacification is described. The 3 affected cases were offspring of consanguinous marriages in two generations; autosomal recessive inheritance is therefore probable. Pain and temperature sensation was lost in the limbs with a resulting mutilating acropathy. Sudomotor function was also impaired. Motor function, tendon reflexes, kinaesthetic sensation and sensory nerve action potentials were normal. Sural nerve biopsy showed a selectively reduced small myelinated nerve fibre population. Corneal histology revealed neurotrophic keratitis. The classification of the hereditary sensory and autonomic neuropathies is discussed. This family represents a previously unrecognized variant.

Hereditary sensory autonomic neuropathy (HSAN) is a group of inherited disorders (total 5 types) that are associated with sensory dysfunction and varying degrees of autonomic dysfunction. HSAN type IV (HSAN-IV) or congenital insensitivity to pain and anhidrosis (CIPA) is a rare genetic disorder inherited in an autosomal recessive manner. We report a case of this very rare genetic disease in a 3-year-old girl child, born to a family in north India with ocular features of neurotrophic keratitis. The diagnosis was made clinically based on the hallmark features of insensitivity to pain and temperature, anhidrosis, self-mutilating behavior with multiple recurrent oral ulcers, nasal bleeds, multiple trophic ulcers over joints, and decreased intellect.
