通过筛选小鼠体内影响神经细胞迁移的基因突变，科学家们发现一个基因在神经细胞内蛋白运输过程中发挥关键作用?？蒲Ъ颐欠⑾秩绻诜⒂男∈笕鄙僬飧龌虮泶锏牡鞍?，它的大脑就会出现严重缺陷。通过研究该基因突变在人类中的情况，科学家们发现相同基因的突变导致了神经退行疾病。一个旨在将分子生物学家和临床遗传学家在一起的信息数据库将实验室和病人之间紧密在了一起：一个来自西欧国家的年轻患者成为了四兄弟中*一个受到该基因突变影响的人；神经退化、认知缺陷和痉挛限制了他对外界刺激产生反应或者控制肌肉的能力，他的一长串症状列表中还出现了癫痫。他在19岁就qushi了。

维也纳分子病理学研究所（IMP）David Keays实验室的科学家们发现这个病人就是他们研究拼图的zui后一个板块。在他们临床遗传学家之前很久，就开始在小鼠体内筛选对神经迁移有影响的基因突变。

脊椎动物的大脑发育强烈依赖于神经细胞正确的产生、迁移、分化和生存。所有这些过程都需要很多基因及其表达的蛋白协同作用，其中任何一个基因突变都可能影响神经细胞的功能。通过生物化学方法诱导基因突变，科学家们发现Vps15是神经正常发育必需的一个基因，相关研究成果于近日发表在《Nature Neuroscience》上。

“它几乎是一个不可能的候选基因。”该研究*作者Thomas Gstrein说道。“人类有超过20000个基因，没有人能猜到Vps15会有这个作用，你不可能只通过Vps15就创造出大脑。

只有通过大量的筛选（与哈佛大学的研究人员合作），科学家们才找除了这个特殊的基因。

随后他们检测了小鼠大脑由于该基因突变产生的特征，并研究了Vps15在大脑发育中发挥作用的分子机制——将它与其他形成细胞骨架的蛋白在了一起。他们发现背后的分子机制之后，他们就转向了Genematcher——一个将他们与临床遗传学家在一起的数据库，该遗传学家有一个病人同源Vps15基因上出现了突变，这个病人也还有神经退行性疾病。

通过检查这个病人、他的兄弟姐妹以及他的父母，研究人员确定Vps15突变使得其表达的蛋白减少，从而引起了神经发育缺陷。在他们的文章中，他们指出Vps15也许在其他神经疾病中也发挥重要作用，如精神分裂症和自闭症，研究人员呼吁在未来的研究中要更加关注这个基因。

By screening the gene mutation that affects the migration of nerve cells in mice, scientists found that a gene plays a key role in the transport of proteins in nerve cells. Scientists have found that if the developing mice lack the protein expressed by the gene, the brain will have serious defects. By studying the mutation of the gene in humans, scientists have found that mutations in the same gene have led to neurodegenerative disease. A molecular biologist and clinical geneticists to be linked to the information database between the laboratory and the patient closely together: one from Western Europe to become the four brothers in the young patients with only one by the gene mutations affecting people; ability of neural degeneration, cognitive deficits and spasm restricted him to external stimuli respond or muscle control, also appeared in his long list of symptoms of epilepsy. He died at the age of 19.

Scientists at the David Keays laboratory at the Vienna Institute of molecular pathology (IMP) found that the patient was the last plate they studied in the jigsaw puzzle. Long before they contacted clinical geneticists, they began screening gene mutations that affect the migration of nerves in mice.

The brain development of vertebrates is strongly dependent on the correct generation, migration, differentiation and survival of the nerve cells. All these processes require a synergistic effect of many genes and their expressed proteins, of which any gene mutation may affect the function of neural cells.  By inducing gene mutation by biochemical methods, scientists found that Vps15 is a necessary gene for normal neural development. The related research results were published in Nature Neuroscience recently.

"It is almost an impossible candidate gene." Thomas Gstrein, the first author of the study, said. "There are more than 20000 genes in humans, and no one can guess that Vps15 will have this effect, and you can't create the brain only through Vps15.

Only through a lot of screening (collaborating with researchers at the Harvard University), scientists are looking for this particular gene.

Then they detected the characteristics of the mouse brain due to the mutation of the gene, and studied the molecular mechanism of Vps15's role in brain development, linking it to other proteins that form cytoskeleton. After they found the molecular mechanisms behind, they turned to Genematcher, a clinical geneticist and they will be linked to the database, the geneticists have a patient appeared on the homologous Vps15 gene mutation, the patient and neurodegenerative diseases.

By examining the patient, his siblings, and his parents, the researchers determined that the Vps15 mutation reduced the protein expressed, resulting in neurodevelopmental deficits. In their articles, they pointed out that Vps15 may also play an important role in other neurological diseases, such as schizophrenia and autism. Researchers call for more attention in the future research.
