GGGGCC repeat expansions in the C9orf72 gene have been identified as a major contributing factor in patients with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Given the overlapping of clinical phenotypes and pathological characteristics between these two diseases and Alzheimer's disease (AD), Parkinson's disease (PD), and essential tremor (ET), we speculated regarding whether C9orf72 repeat expansions also play a major role in these three diseases. Using the repeat-primed polymerase chain reaction method, we screened for C9orf72 in three groups of patients with PD ( n = 911), AD ( n = 279), and ET ( n = 152) in the Chinese Han population. There were no pathogenic repeats (>30 repeats) detected in either the patients or controls ( n = 314), which indicated that the pathogenic expansions of C9orf72 might be rare in these three diseases. However, the analysis of the association between the number of repeats ( p = 0.001), short/intermediate genotype (short. Introduction A hexanucleotide (GGGGCC) repeat expansion in the first intron of the C9orf72 gene was recently identified as a major contributing factor to the chromosome 9p21-linked diseases amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) (Dejesus-Hernandez et al., ). As previously reported, the C9orf72 mutation accounts for 23.5–47% of familial ALS/FTD and 4.1–21.0% of sporadic ALS in white populations (Dejesus-Hernandez et al.,; Renton et al.,; Gijselinck et al., ). ![]() Algunas palabras de reflexion tomadas del libro El Esclavo de Francisco J.

The pathogenic mechanism of repeat expansions primarily includes interference with the normal expression of the encoded protein or the loss of protein function through the generation of abnormal toxic RNA foci that disrupt normal cellular pathways (Renton et al.,; Sha and Boxer, ). There is no doubt that the overlapping presentations of clinical phenotypes, pathological characteristics, and gene mutations exist among Parkinson disease (PD), Alzheimer's disease (AD), and ALS/FTD (Hudson,; Piguet et al.,; Arighi et al.,; Floris et al.,; O'Dowd et al., ). First, in the examination of clinical phenotypes, relatives of patients with ALS have an increased risk for developing PD and AD, additionally, some ALS/FTD patients have developed the associated features of Parkinsonism and movement disorders (Hsiung et al.,; Takada et al.,; Kohli et al., ). Hum tumhe chahte hai song mp3. Second, the presence of TAR DNA-binding protein-43(+) intranuclear inclusions, which are the pathological feature of chromosome 9p21-linked ALS/FTD, have been detected in PD and AD patients (Nakashima-Yasuda et al.,; Boeve et al., ). Finally, mutations in the microtubule-associated protein tau (MAPT) gene could cause a spectrum of phenotypes which include ALS, Parkinsonism, and cognitive impairment (O'Dowd et al., ). Given the considerations above, one question has yet to be addressed. Could the C9orf72 repeat expansions account for other neurodegenerative disorders, such as AD, PD, and essential tremor (ET)? In C9orf72, Repeat expansions exceeding 30 units have been suggested to be pathological in ALS/FTD patients (Dejesus-Hernandez et al., ). Ras g and the afrikan space program rar gratis. Interestingly, pathogenic expansions have also been observed in patients with PD, AD, progressive supranuclear palsy, corticobasal degeneration, and Lewy body dementia (Xi et al.,; Cacace et al.,; Lesage et al., ), which further indicates that the phenotypes that are associated with repeat expansions could include the spectrum of cognitive impairment and movement disorder syndromes.
