家族性肌萎缩性侧索硬化症(FALS)以孟德尔方式作为常染色体显性(DFALS)或常染色体隐性(RFALS)性状传播。DFALS和RFALS在基因上都是异质的。15%的DFALS家族在21号染色体上编码的Cu, Zn超氧化物歧化酶(SOD1)基因发生突变。其中一种形式的RFALS位点位于染色体2q33上。据报道,在DFALS家族中有46个SOD1基因突变。在大多数情况下,这些突变导致SOD1活性降低和蛋白质半衰期缩短。过度表达突变SOD1蛋白的转基因小鼠会发生als样疾病,这表明DFALS中运动神经元的退化是由突变SOD1获得新的毒性功能而不是SOD1活性降低引起的。本文讨论了突变SOD1神经毒性功能的几种可能机制。神经学1996;47(补充2):S27-S35
Familial amytrophic lateral sclerosis (FALS) is transmitted in a mendelian fashion as an autosomal dominant (DFALS) or an autosomal recessive (RFALS) trait.Both DFALS and RFALS are genetically heterogeneous. Fifteen percent of DFALS families have mutations in the gene for Cu, Zn superoxide dismutase (SOD1) which is coded on chromosome 21. The locus for one form of RFALS maps to chromosome 2q33. Forty-six mutations in the SOD1 gene have been reported in DFALS families. These mutations result in decreased SOD1 activity and shortened half-life of the protein in most instances. Transgenic mice overexpressing mutated SOD1 protein develop an ALS-like disease which suggests that the degeneration of motor neurons in DFALS is caused by the gain of a novel toxic function by mutated SOD1 rather than by the decrease of SOD1 activity. Several possible mechanisms of the novel neurotoxic function of mutated SOD1 are discussed. NEUROLOGY 1996;47(Suppl 2): S27-S35
