摘要

脑部畸形很常见,严重程度不一,有的可以忽略不计,有的则可能致命。其病因尚未完全阐明。在此,我们报告了脑畸形、智力障碍和癫痫发作患者中核心蛋白质折叠机制 TRiC/CCT 的致病变异。伴侣素 TRiC 是一种强制性异质偶联物,我们发现了其八个亚基中七个亚基的变异,所有这些变异都通过不同的机制损害了其功能或组装。对源自患者的成纤维细胞进行的转录组和蛋白质组分析表明了 TRiC 受损的各种后果。研究结果揭示了蛋白质折叠在中枢神经系统发育过程中意想不到的潜在广泛作用,并定义了 "TRiCopathies "的疾病谱。

Brain malformations and seizures by impaired chaperonin function of TRiC
Malformations of the brain are common and vary in severity, from negligible to potentially fatal. Their causes have not been fully elucidated. Here, we report pathogenic variants in the core protein-folding machinery TRiC/CCT in individuals with brain malformations, intellectual disability, and seizures. The chaperonin TRiC is an obligate hetero-oligomer, and we identify variants in seven of its eight subunits, all of which impair function or assembly through different mechanisms. Transcriptome and proteome analyses of patient-derived fibroblasts demonstrate the various consequences of TRiC impairment. The results reveal an unexpected and potentially widespread role for protein folding in the development of the central nervous system and define a disease spectrum of “TRiCopathies.”

期刊介绍: Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
