Modern genomic approaches have made enormous contributions to improving our understanding of the function, development and evolution of the nervous system, and the diversity within and between species. However, most of these research advances have been recorded in countries with advanced scientific resources and funding support systems. On the contrary, little is known about, for example, the possible interplay between different genes, non-coding elements and environmental factors in modulating neurological diseases among populations in low-income countries, including many African countries. The unique ancestry of African populations suggests that improved inclusion of these populations in neuroscience-related genomic studies would significantly help to identify novel factors that might shape the future of neuroscience research and neurological healthcare. This perspective is strongly supported by the recent identification that diseased individuals and their kindred from specific sub-Saharan African populations lack common neurological disease-associated genetic mutations. This indicates that there may be population-specific causes of neurological diseases, necessitating further investigations into the contribution of additional, presently-unknown genomic factors. Here, we discuss how the development of neurogenomics research in Africa would help to elucidate disease-related genomic variants, and also provide a good basis to develop more effective therapies. Furthermore, neurogenomics would harness African scientists' expertise in neuroscience, genomics and bioinformatics to extend our understanding of the neural basis of behaviour, development and evolution.
现代基因组学方法为增进我们对神经系统的功能、发育、进化以及物种内部和物种之间的多样性的理解做出了巨大贡献。然而,这些研究进展大多记录在拥有先进科学资源和资金支持体系的国家。相反,对于低收入国家(包括许多非洲国家)人群中不同基因、非编码元件和环境因素在调节神经疾病方面可能存在的相互作用,我们却知之甚少。非洲人群独特的祖先背景表明,在神经科学相关的基因组研究中更好地纳入这些人群,将极大地有助于识别可能塑造神经科学研究和神经医疗未来的新因素。最近的一项发现有力地支持了这一观点,即来自撒哈拉以南非洲特定人群的患病个体及其亲属缺乏常见的神经疾病相关基因突变。这表明神经疾病可能存在特定人群的病因,因此有必要进一步研究其他目前未知的基因组因素的作用。在此,我们讨论非洲神经基因组学研究的发展将如何有助于阐明与疾病相关的基因组变异,也为开发更有效的治疗方法提供良好基础。此外,神经基因组学将利用非洲科学家在神经科学、基因组学和生物信息学方面的专业知识,扩展我们对行为、发育和进化的神经基础的理解。
