亨廷顿氏舞蹈病:从极端中学习
--
摘要:亨廷顿氏病(HD)是一种以进展性疾病为特征的致命性遗传性神经退行性疾病。
运动、精神障碍和认知能力下降。这可能是由一种新的基因突变导致的,导致人类成为全球最大的细胞性疾病。
亨廷顿蛋白基因突变体mtHtt的表达,该基因对人类中枢神经系统疾病的致病作用尤其敏感。
对于这种毁灭性的疾病和致命的疾病,目前还没有可用的治疗方法。这是医疗设计面临的主要挑战之一。
高效的临床和临床试验是我们观察到的最巨大的临床试验可变性的结果。许多情况下,这种可变性是不受控制的。
在这项研究中,不同受试者之间的疾病进展速度明显不同,这很可能是由遗传缺陷和遗传缺陷引起的。
环境因素。自那以来,大多数人都没有从CAG的扩张和持续时间表中得到解释。
患有先天性心脏病的患者中,CAG的长度范围有限,跨度为41-47岁,但他们的临床发病年龄较小。
童年是人类生命的第八十年。全基因组生物协会研究小组(GWAS)已经发现了一些潜在的基因。
而且,来自其他遗传基因的非常有限的贡献也无法解释我们在临床上观察到的极端情况。
研究对象是一名非青少年HHD患者,他们的CAGn水平和疾病持续时间以及早发和晚发疾病的发病率和病程匹配。
研究发现,发病越早,大脑萎缩越快,发病越早,大脑萎缩越慢。
这表明,发病年龄是疾病进展的最大斜率的一个强有力的预测因子。我们对这种疾病的生物学特征的理解是错误的。
导致发病年龄和进展速度不同的因素可能会揭示导致这种疾病的相关因素。
了解和预测癌症进展率可能有助于我们确定新的治疗目标。
此前,人们从HD受试者的血液和血液中发现了改变的代谢、基因、基因和转录水平的标记。
这代表了两条可能不会影响进展的途径。我们将提出进一步扩大我们早期和晚期这两个队列的方法。
受试者发病后,可以通过神经影像检查来评估他们的临床进展,评估和评估他们的表现是不偏颇的。
有针对性的研究包括血细胞和脑脊液标记物,以寻找区分新的线索,以减少进展中的差异。
英文摘要
Huntington’s disease: Learning from Extremes
Abstract: Huntington's disease (HD) is a fatal genetic neurodegenerative disorder characterized by progressive
motor, psychiatric and cognitive decline. It is caused by a genetic mutation leading to the global cellular
expression of the mutant huntingtin protein (mtHtt), which is particularly toxic to the CNS. Disease modifying
treatments are not yet available for this devastating and lethal disease. One of the challenges for designing
efficient clinical trials is the tremendous clinical variability that is observed. Much of that variability is contained
in the markedly different rates of progression between subjects, which are likely caused by both genetic and
environmental factors. Variable progression is not explained by the CAG expansion length since the vast majority
of individuals with HD fall in a limited range of CAG lengths spanning 41-47 yet have ages of clinical onset from
childhood to the 8th decade of life. Genome-wide association studies (GWAS) have uncovered some potential
and very limited contributions from other genes and do not explain the extremes observed clinically. We have
studied non-juvenile HD subjects matched for CAGn and disease duration and having early and late onset and
find that earlier onset is associated with more rapid cerebral atrophy and older onset with slower cerebral atrophy,
suggesting that age-of-onset is a strong predictor of the slope of progression. Understanding the biological
factors that underlie divergent ages of onset and rates of progression may uncover correlates that enable
understanding and predicting rates of progression and may help identify new treatment targets. We have
previously identified altered metabolomic, genetic, and transcriptomic markers from the blood and in HD subjects
that represent pathways that could influence progression. We propose to expand our cohort of early and late
onset subjects, evaluate their progression clinically and by neuroimaging, and to perform both unbiased and
targeted studies of blood and csf markers to seek distinguishing clues to the variance in progression.
