Abstract
Objective: This study aimed to determine the distribution of the most commonly mutated genes (SOD1, TARDBP, FUS/TLS, and C9ORF72) associated with familial amyotrophic lateral sclerosis (FALS) and the association between genotype and phenotype in 242 Chinese patients.Methods: A total of 58 families were screened for ALS-associated mutations in SOD1,TARDBP, FUS, and C9ORF72 hexanucleotide repeat expansion. These mutations were analyzed to evaluate the relationship between genotype and phenotype in Chinese FALS patients.Results: Partial clinical data were obtained for 242 relatives of the 58 analyzed families, with a male-to-female ratio of 1.2:1 and a mean age of disease onset of 45.9±12.0 (13-80) years. 26 mutations associated with pathogenesis were identified in 32 probands from 58 different families. Mutations in SOD1, FUS, TARDBP, and C9ORF72 accounted for 32.8%, 12.1%, 8.6%, and 1.7% of FALS, respectively. FALS patients showed longer survival times; however, bulbar-onset ALS and the male-to-female ratio for them were lower than those reported previously. The site of onset, age of onset, and lifespan differed in FALS patients with SOD1, TARDBP, and FUS mutations.Discussion: In this study, patients with SOD1 mutations exhibited heterogeneous survival times that showed a bimodal distribution, while patients with FUS mutations showed rapid disease progression. Our results showed the relative contributions of the different types of mutations associated with ALS and provided phenotype-genotype correlations with clinical features in Chinese patients.

The clinical assessment of amyotrophic lateral sclerosis patients' prognosis by ZNF512B gene, neck flexor muscle power score and body mass index (BMI). BMC Neurol 2018; 18:211. [PMID: 30567526 PMCID: PMC6299516 DOI: 10.1186/s12883-018-1219-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2018] [Accepted: 12/05/2018] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Assessment on the prognosis of amyotrophic lateral sclerosis (ALS) is becoming a focus of research in recent years since there is no effective treatment. The aim of the research is to explore the major factors involving in prognosis of ALS patients through long-term follow-up. METHODS ALS patients' DNA extracted from peripheral blood white cells were detected for the risk allele by single nucleotide polymorphism (SNP) analysis. Neck flexor muscle score and body mass index (BMI) were recorded during Medical Research Council follow-up using manual muscle testing method. RESULTS ALS patients with risk alleles (C) deteriorated rapidly with poor clinical outcome. It seemed that the higher neck flexor muscle strength score in ALS patients with the longer survival time but without significant correlation (p > 0.05). The lower the basal body mass index, the shorter the survival time and the faster deterioration (p < 0.05). The patients with body mass index less than 22.04 seemed to have short survival time than those with BMI more than 22.04 (p < 0.05), however, the speed of deterioration in two groups of patients had no significant difference (p > 0.05). CONCLUSION The risk (C) allele of the SNP (rs2275294) in the ZNF512B gene, cervical flexor muscle power and body weight index might have clinical potential for ALS prognostication, since these indicators is so simple to perform that they might be very suitable for primary clinics and even community medical institutions to carry out.

Neurol Sci 2018; 39:1261-1266.

Abstract
Amyotrophic lateral sclerosis (ALS), the most common motor neuron disease, appears to result from the combination of genetic and environmental factors. Whether the rs2275294 polymorphism in the ZNF512B gene influences ALS risk is controversial. We meta-analysed the association between rs2275294 and ALS risk based on evidence published in the PubMed database. Five case-control studies involving 2559 patients with sporadic ALS and 5740 controls were analysed. Based on random-effects meta-analysis, the polymorphism rs2275294 was associated with increased risk of ALS disease in an allele model (C vs. T: OR 1.222, 95%CI 1.057 to 1.414, p = 0.007). The available evidence suggests that the ZNF512B polymorphism rs2275294 is associated with ALS risk. These results should be validated in large, well-designed studies, especially in non-Asian populations.

Abstract
BACKGROUND Amyotrophic lateral sclerosis (ALS), the most common motor neuron disease, is thought to result from interaction of genetic and environmental risk factors. Whether the potentially functional exonic P413L variant in the chromogranin B gene influences ALS risk and age at onset is controversial. METHOD We meta-analysed or other studies assessing the association between the P413L variant and ALS risk or age at ALS onset indexed in Web of Science, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed databases. RESULTS Five case-control studies were analysed, involving 2639 patients with sporadic ALS, 201 with familial ALS and 3381 controls. No association was detected between risk of either ALS type and the CT + TT genotype or T-allele of the P413L variant. Age at ALS onset was similar between carriers and non-carriers of the T-allele. CONCLUSION The available evidence suggests that the P413L variant of chromogranin B is not associated with ALS risk or age at ALS onset. These results should be validated in large, well-designed studies.

Abstract
AIMS Parkinson's disease (PD) is one of the most common neurodegenerative disorders; its etiology includes both genetic and environmental factors and their interactions. The ZNF512B, SLC41A1, and ALDH2 genes have recently been identified as contributing to PD. In this study we investigated the association of alleles of these genes with PD in the Iranian population. METHODS In a case-control study, rs2275294, rs11240569, and rs4767944, three single nucleotide polymorphisms in ZNF512B, SLC41A1, and ALDH2 genes, respectively, were genotyped in 490 PD patients and 490 controls. The genotype and allele frequencies were compared between the two groups using chi-square and logistic regression tests. RESULTS A significant association between the rs11240569 polymorphism and a reduced risk of PD was found (p = 0.014, OR = 0.76, 95% CI: 0.60-0.94 for allele frequencies). We did not find any associations between PD and the rs2275294 and rs4767944 polymorphisms. CONCLUSION The association of rs11240569 polymorphism in SLC41A1 gene with reduced risk of PD was replicated in our population.
