New HSN2 mutation in Japanese patient with hereditary sensory and autonomic neuropathy type 2
1Department of Neurology, Clinical Neuroscience Branch, Niigata University Brain Research Institute, Niigata, Japan.
Abstract:
The authors report a Japanese patient with hereditary sensory and autonomic neuropathy type 2 (HSAN2) who has a new mutation of the HSN2 gene. The pathologic findings of the patient matched those of Canadian patients. They identified a homozygous 1134-1135 ins T mutation, resulting in a frameshift, and the subsequent premature stop codon at residue 378. These observations support the hypothesis that HSN2 is a causative gene for HSAN2.
