Spastin gene mutation in Japanese with hereditary spastic paraplegia.
Hereditary spastic paraplegia (HSP) is a cluster of genetically heterogeneous disorders that has spastic paraplegia as the central feature. Autosomal dominant HSP (AD-HSP) is also genetically heterogeneous and seven loci have been identified so far on chromosomes 14q (SPG3), 2p (SPG4), 15q (SPG6), 8q (SPG8), 12q (SPG10), 19q (SPG12), and 2q (SPG13). Among them, the SPG4 gene named spastin (GenB...
متن کاملLate-onset spastic ataxia phenotype in a patient with a homozygous DDHD2 mutation
Autosomal recessive cerebellar ataxias and autosomal recessive hereditary spastic paraplegias (ARHSPs) are clinically and genetically heterogeneous neurological disorders. Herein we describe Japanese siblings with a midlife-onset, slowly progressive type of cerebellar ataxia and spastic paraplegia, without intellectual disability. Using whole exome sequencing, we identified a homozygous missens...
متن کاملSPG3A gene polymorphisms in hereditary spastic paraplegia
Objective: This study aimed to analyze the hereditary spastic paraplegia (HSP)/spastic paraplegia 3A (SpG3A) genomic structure as well as the polymorphisms in SPG3G genomic structure by comparing with the normal subjects. Methods: A total of 66 sporadic cases with HSP were collected from April 2014 to September 2016. Genomic DNA extraction was performed, and all coding exons and junction region...
متن کاملSPG20 mutation in three siblings with familial hereditary spastic paraplegia
Troyer syndrome (MIM#275900) is an autosomal recessive form of complicated hereditary spastic paraplegia. It is characterized by progressive lower extremity spasticity and weakness, dysarthria, distal amyotrophy, developmental delay, short stature, and subtle skeletal abnormalities. It is caused by deleterious mutations in the SPG20 gene, encoding spartin, on Chromosome 13q13. Until now, six un...
متن کاملhereditary spastic paraplegia: from gene to clinic
objective hereditary spastic paraplegia (hsp) is a degenerative disease of genetic origin affecting the corticospinal tracts in the spinal cord. there are three forms of inheritance: autosomal dominant hsp, autosomal rececive hsp and x-linked hsp. this disease is characterized by progressive spasticity of leg muscles with varying degrees of stiffness and weakness of other muscle groups. in this...
