Detection of hereditary motor sensory neuropathy type I in childhood.
Clinical signs and slowed motor nerve conduction velocities were found in 17 of 36 children under 10 years of age who had one parent with hereditary motor sensory neuropathy type I (HMSN I). Four children had slowed conduction velocities at one year or less. Clinical signs were subtle and included pes planus, distal foot wasting, weakness of ankle eversion and dorsiflexion and areflexia. HMSN I...
متن کاملHereditary sensory neuropathy type I
Hereditary sensory neuropathy type I (HSN I) is a slowly progressive neurological disorder characterised by prominent predominantly distal sensory loss, autonomic disturbances, autosomal dominant inheritance, and juvenile or adulthood disease onset. The exact prevalence is unknown, but is estimated as very low. Disease onset varies between the 2nd and 5th decade of life. The main clinical featu...

Hereditary sensory and autonomic neuropathy type II (HSAN2) is a condition that primarily affects the sensory nerve cells (sensory neurons), which transmit information about sensations such as pain, temperature, and touch. These sensations are impaired in people with HSAN2. In some affected people, the condition may also cause mild abnormalities of the autonomic nervous system, which controls i...
متن کاملHereditary 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.
متن کاملHereditary sensory and autonomic neuropathy: A case report
A 24-year old female patient with the history of pressure ulcers in distal extremities resulted in severe deformity will be reported. Her disease started when she was 9 years old and a similar history was found in her brother. In physical examination, pain and temperature sensations were impaired in distal extremities. Nerve conduction velocity showed impaired sensory and normal motor responses...
