In six families with hereditary neuropathy with liability to pressure palsies (HNPP) the 17p11.2 deletion was absent, but single strand conformation-analysis and subsequent sequencing demonstrated a heterozygous G-insertion in a stretch of six Gs at nt 276281 of the PMP22 gene, resulting in a frame shift after Gly94. Haplotype comparison of the six families revealed common ancestry. We compared...

The hereditary motor and sensory neuropathies (HMSN) represent a genetically heterogeneous collection of disorders in which patients develop a progressive muscular atrophy and sensory neuropathy of the distal extremities. Although Dyck' has noted seven types, the best described of these are HMSN types I and II (Charcot-Marie-Tooth disease) and Dejerine-Sottas (DS) disease, HMSN III. In contrast...

Charcot-Marie-Tooth disease (CMT), also known as hereditary motor and sensory neuropathy, is the most common inherited peripheral nerve disorder. Missense mutations, such as K141N, in the small heat shock protein HSPB8 are known to cause distal hereditary motor neuropathy 2A (dHMN2A) or Charcot-Marie-Tooth neuropathy type 2L (CMT2L). However, of critical clinical significance, very few specific...

familial amyloid polyneuropathy (fap) type iv (finnish) is a rare clinical entity with challenging neuropathy and cosmetic deficits. amyloidosis can affect peripheral sensory, motor, or autonomic nerves. nerve lesions are induced by deposits of amyloid fibrils and treatment approaches for neuropathy are challenging. involvement of cranial nerves and atrophy in facial muscles is a real concern i...

A 65-year-old woman with a 5-year history of type 2 diabetes (a recent hemoglobin A1C level was 9.5%) reports the recent onset of burning, tingling, and stabbing pain in her feet that is worse at night and interferes with sleep and activities of daily living. Her medications include 500 mg of metformin and 2 mg of glimepiride, each taken twice dai...

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.

Several types of hereditary sensory and autonomic neuropathies (HSAN) are reported in literatures. We describe here a case of type IV HSAN, the second commonest variety of HSAN and attempt to present a short review of literature. Families of these children need support, proper guidance and counseling for taking better care of the diseased. The goal should be to help them achieve independent fun...

Two siblings with a distal motor neuropathy experienced cramping and difficulty in relaxing their muscles after voluntary contraction. Electromyographic recordings at rest revealed repetitive high voltage spontaneous electrical discharges that were accentuated after voluntary contraction and during ischaemia. Regional neuromuscular blockage with curare indicated hyperexcitability of peripheral ...

Multifocal acquired demyelinating sensory and motor (MADSAM) neuropathy is characterized by an asymmetric multifocal pattern of motor and sensory loss, and conduction block and other features of demyelination in nerve conduction studies. MADSAM neuropathy needs to be differentiated from chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN). In classic CI...
