由于在许多长期的纵向研究中突然获得了分子遗传数据,特别是多基因得分,最近人们对基因-环境相互作用的研究兴趣与日俱增。确定和估计统计相互作用伴随着几个分析和推理挑战;当用于整合观察、基因组和社会科学数据时,这些挑战更加突出。我们阐述了这些关键挑战中的一些,为基因-环境相互作用的研究提供了新的视角,并在结束时为这一领域的研究提供了一些实践指导。鉴于强大的多基因评分的突然出现,我们预计此类评分与环境之间相互作用的研究测试将大幅增加。我们讨论的问题,如果没有得到适当的解决,可能会影响基因与环境相互作用研究的持久科学价值。
Interest in the study of gene–environment interaction has recently grown due to the sudden availability of molecular genetic data—in particular, polygenic scores—in many long-running longitudinal studies. Identifying and estimating statistical interactions comes with several analytic and inferential challenges; these challenges are heightened when used to integrate observational genomic and social science data. We articulate some of these key challenges, provide new perspectives on the study of gene–environment interactions, and end by offering some practical guidance for conducting research in this area. Given the sudden availability of well-powered polygenic scores, we anticipate a substantial increase in research testing for interaction between such scores and environments. The issues we discuss, if not properly addressed, may impact the enduring scientific value of gene–environment interaction studies.
