    • This invention relates to methods and compositions useful for detecting mutations which cause Familial Dysautonomia. Familial dysautonomia (FD; Riley-Day syndrome), an Ashkenazi Jewish disorder, is the best known and most frequent of a group of congenital sensory neuropathies and is characterized by widespread sensory and variable autonomic dysfunction. Previously, we mapped the FD gene, DYS , to a 0.5 cM region of chromosome 9q31 and showed that the ethnic bias is due to a founder effect, with >99.5% of disease alleles sharing a common ancestral haplotype. To investigate the molecular basis of FD, we sequenced the minimal candidate region and cloned and characterized its 5 genes. One of these, IKBKAP , harbors two mutations that can cause FD. The major haplotype mutation is located in the donor splice site of intron 20. This mutation can result in skipping of exon 20 in the mRNA from FD patients, although they continue to express varying levels of wild-type message in a tissue-specific manner. RNA isolated from patient lymphoblasts is primarily wild-type, whereas only the deleted message is seen in RNA isolated from brain. The mutation associated with the minor haplotype in four patients is a missense (R696P) mutation in exon 19 that is predicted to disrupt a potential phosphorylation site. Our findings indicate that almost all cases of FD are caused by an unusual splice defect that displays tissue-specific expression; and they also provide the basis for rapid carrier screening in the Ashkenazi Jewish population.
    • 本发明涉及可用于检测引起家族性躯体障碍的突变的方法和组合物。 家族性失眠症(FD; Riley-Day综合征),一种Ashkenazi犹太病症,是一组先天性感觉神经病最知名和最常见的,其特征在于广泛的感觉和可变自主神经功能障碍。 以前,我们将FD基因DYS映射到染色体9q31的0.5cM区域,并显示种族偏倚是由于创始者效应,> 99.5%的疾病等位基因共享共同的祖先单体型。 为了研究FD的分子基础,我们对最小候选区进行了测序,克隆并表征了其5个基因。 其中之一,IKBKAP,有两个可能导致FD的突变。 主要的单倍型突变位于内含子20的供体剪接位点。这种突变可导致FD患者mRNA中外显子20的跳跃,尽管它们以组织特异性方式继续表达不同程度的野生型信息。 从患者淋巴母细胞分离的RNA主要是野生型,而只有从脑分离的RNA中才能看到已删除的信息。 与4例患者中较小单倍型相关的突变是外显子19中的错义(R696P)突变,预测会破坏潜在的磷酸化位点。 我们的研究结果表明,几乎所有FD的病例都是由显示组织特异性表达的不寻常的拼接缺陷引起的; 它们也为在阿什肯纳西犹太人群体中快速的载体筛查提供了基础。

    • The present invention provides brain cells, such as normal brain cells, apolipoprotein E deficient brain cells, or apoE4 containing brain cells, that are treated with a compound which can modulate integrins and/or integrin receptors to produce increased sequestration of and/or accumulation of and/or uptake of A beta , and/or changed in cathepsin D content and/or lysosomal dysfunction, and/or microglia activation in the brain cells. The present invention also provides methods for producing such cells and methods for using the cells for screening an agent or substance that modulates the sequestration of and/or accumulation of and/or uptake of A beta , and/or lysosomal dysfunction, and/or changes in cathepsin D content and/or microglia activation in the brain cells. The method further provides a new therapeutic target, antagonism of glutamate receptors, for the treatment of neurodegenerative diseases which are characterized by inter alia , abnormal amyloid uptake and/or accumulation.

    • The methodologies of the present invention demonstrate that a critical balance between pro- and anti-amyloidogenic molecules exists that regulates amyloid formation and cell death in Alzheimer's disease and Parkinson's disease. beta -Synuclein, the non-amyloidogenic homologue of alpha -synuclein, is a negative modulator of alpha -synuclein and A beta aggregation, having neuroprotective properties against alpha -synuclein and A beta neurotoxicity and that beta -synuclein and therapeutic agents derived therefrom block amyloidogenesis and neurodegeneration in vivo . The method of the present invention establishes that beta -synuclein blocks A beta aggregation either by direct inhibition of A beta amyloidogenesis or indirectly via either alpha -synuclein or its 35 a.a. NAC region, inferring neuroprotective characteristics within the effected cells. The generation of a transgenic mouse line and a cell-free system overexpressing alpha -synuclein characterizes the mechanisms by which beta -synuclein blocks alpha -synuclein and A beta aggregation and that this mechanism offers protection to the cell against amyloid formation as seen in the pathologies of Alzheimer's disease and Parkinson's disease.
