戈谢病 (GD) 是最常见的溶酶体贮积病 (1),是一种常染色体隐性遗传的鞘糖脂代谢疾病,由溶酶体酶、酸性 s-葡萄糖苷酶 [s-Glc;s-Glc;] 活性降低引起。 N-酰基-鞘氨醇基-0-β-D-葡萄糖苷:葡萄糖水解酶(EC 3.2.1.45)](2,3)。该酶的主要底物葡萄糖神经酰胺 (GC) 在单核细胞/巨噬细胞系统的溶酶体中逐渐积累,导致该疾病出现多种临床表现 (4,5)。根据神经病性受累的不存在或存在及其严重程度,描述了三种不同的表型 (1)。 1 型 GD(非神经病性)是最常见的表型,其特征是临床发病年龄和网状内皮表现程度存在显着差异 (6-8)。尽管 1 型 GD 在德系犹太人中发生的频率最高 (9),但在许多不同种族背景的患者中也有描述 (10-12)。相比之下,2 型 GD(急性神经病)是一种罕见的全民族严重神经退行性疾病,可导致两岁前死亡 (4)。 3 型 GD 主要发生在瑞典,其特点是不同程度的神经病、内脏和骨骼受累 (13)。尽管最初描述的是具有 Norrbottnian 血统的瑞典个体,但其他具有神经病性和严重网状内皮表现的非瑞典儿童已被归类为 3 型 GD (14,15)。 Norrbottnian 3 型 GD 患者可能是 s-Glc 结构基因位点上单个突变等位基因的纯合子,因为所有受影响的个体都是 1600 年代结婚的一对夫妇的后裔 (13)。
Gaucher disease (GD), the most prevalent lysosomal storage disease (1), is an autosomal recessive disorder of glycosphingolipid metabolism, resulting from the reduced activity of the lysosomal enzyme, acid s-glucosidase [s-Glc; N-acyl-sphingosyl-0-β-D-glucoside: glucohydrolase (EC 3.2.1.45)] (2,3). The progressive accumulation of this enzyme’s major substrate, glucosyl ceramide (GC), within the lysosomes of the monocyte/macrophage system, leads to the diverse clinical manifestations of the disease (4,5). Three distinct phenotypes have been delineated based on the absence, or presence and severity of neuronopathic involvement (1). Type 1 GD (non-neuronopathic) is the most prevalent of the phenotypes and is characterized by remarkable variability in the age at clinical onset and degree of reticuloendothelial manifestations (6–8). Although occurring with highest frequency among Ashkenazi Jews (9), Type 1 GD has been described in patients from many different ethnic backgrounds (10–12). In contrast, Type 2 GD (acute neuronopathic) is a rare, panethnic, severe neurodegenerative disease which leads to death before two years of age (4). Type 3 GD, which occurs primarily in Sweden, is characterized by variable neuronopathic, visceral and boney involvement (13). Although originally described in Swedish individuals of Norrbottnian descent, other non-Swedish children with neuronopathic and severe reticuloendothelial manifestations have been classified as Type 3 GD (14,15). The Norrbottnian Type 3 GD patients presumably are homozygous for a single mutant allele at the s-Glc structural gene locus, since all affected individuals were descended from a single couple who were married in the 1600s (13).
