| Research Abstract |
It is important to evaluate the genotype/phenotype correlation to establish the strategy of the gene therapy for neurodegenerative disorders. I studied the genotype/phenotype correlation of Japanese patients with Gaucher disease. Seven common mutations were screened, resuting in the absence of N370S and 84GG mutations among Japanese patients. In contrast these mutations accounted for approximately 80% of total mutated alleles among Jews. Patients with homozygous for N370S are asymtomatic. These data indicate that Japanese patients are more severe than Jewish patients. Homozygotes for the L444P mutation are tightly linked to type 3a in Sweden, however, phenotypic expressions of homozygotes for the L444P mutation in Japan are variable.
These data suggested that one should pay attention to the ethnicity to constitute the strategy of gene therapy for neurogegenerative disorders.
