The mucopolysaccharidoses are a group of genetic diseases characterized by storage of incompletely degraded glycosaminoglycans. Such storage causes marked distortion of many tissues with consequent severe somatic changes and mental retardation. Storage of glycosaminoglycans results from markedly diminished activity of specific hydrolases requisite for the normal degradation of glycosaminoglycans. The specific enzymic defects have been identified in nine different diseases. In some cases evidence has been obtained indicating the existence of additional allelic diseases based on the same enzyme. The knowledge obtained from these studies has made prenatal diagnosis possible and has led to the possibility that therapy may be undertaken utilizing enzyme replacement.
黏多糖贮积症是一组遗传性疾病,其特征是不完全降解的糖胺聚糖蓄积。这种蓄积导致许多组织明显变形,从而引起严重的躯体变化和智力发育迟缓。糖胺聚糖的蓄积是由于糖胺聚糖正常降解所需的特定水解酶活性显著降低所致。已在九种不同疾病中发现了特定的酶缺陷。在某些情况下,已获得证据表明基于同一种酶存在其他等位基因疾病。从这些研究中获得的知识使产前诊断成为可能,并带来了利用酶替代疗法的可能性。
