Hereditary sensory and autonomic neuropathy type I

Hereditary sensory and autonomic neuropathy (HSAN) type 1 is a rare hereditary neurological disorder. Two brothers aged 17 and 14 years had HSAN type 1 as both had big ulcers on feet, mutilation, dissociated anaesthesia, absent ankle jerks and normal hands. Probably these are first cases of HSAN type 1 in Indian literature.
