| Research Abstract |
Gaucher disease (GD) is one of lipidoses and caused by a deficiency of glucocerebrosidase. This enzyme defect results in accumulation of glucocerebroside in reticuloendothelial systems. Based on the presence and severity of neurological symptoms, GD is classified into three main phenotypes : typel-non-neuronapthic form, type2 -acute neuronopathic form and type 3-subacute neuronopathic form. The clinical hallmark of this disorder is variability in phenotypic expression. This phenotypic variation may result from molecular heterogeneity. Therefore there is no consensus regarding optimal dosage of enzyme.
We investigated the detailed phenotypic expression, genotype-phenotype correlation and optimal treatment in Japanese patients with Gaucher disease.
We reported the rare type 3 form which manifest communicating hydrocephalus and fbrous thickening of spleen and liver capsules. The high incidence of skeletal complications improvement was significant. these observation suggest that macrophages may be good target cells for ex vivo gene therapy Sly disease.
