The potential for privacy infringement is high, given the sensitive nature of genetic information and its implications for individuals and their relatives. Effective privacy protection measures are essential to mitigate these risks. Current research highlights the major privacy threats and suggests various privacy-protection techniques for genomic data sharing, particularly in direct-to-consumer genetic testing and forensic analyses (Bonomi et al., 2020). Furthermore, the increasing commercialization of DNA technologies necessitates a security-by-design approach to protect the confidentiality, integrity, and availability of genomic data (Arshad et al., 2021). Addressing these ethical and privacy concerns is crucial for advancing genomic research within a safe and ethical framework. 5 Opportunities for Future Research and Development 5.1 Development of new statistical methods for genomic data The rapid advancement of high-throughput technologies, such as next-generation sequencing, has resulted in the generation of vast and complex genomic datasets. Traditional bioinformatics pipelines are often insufficient to fully leverage these datasets, necessitating the development of novel statistical methods and computational paradigms. For instance, the transition from string-based to graph-based representations of reference genomes is a promising direction that could enhance the analysis of large-scale genomic data (Consortium, 2016). Additionally, the integration of machine learning techniques, particularly interpretable machine learning (iML), can help in making complex models more intelligible and actionable for genomic research (Watson, 2021) (Figure 2). Figure 2 The classic bioinformatics workflow spans data collection, model training, and deployment. iML augments this pipeline with an extra interpretation step, which can be used during training and throughout deployment (incoming solid edges). Algorithmic explanations (outgoing dashed edges) can be used to guide new data collection, refine training, and monitor models during deployment (Adopted from Watson, 2021) 5.2 Improving the accuracy and interpretability of genomic predictions The complexity and volume of genomic data require advanced statistical methods to improve the accuracy and interpretability of predictions. Interpretable machine learning (iML) is a burgeoning field that aims to make the predictions of machine learning models more understandable to end-users, which is crucial for the realization of precision medicine (Watson, 2021). Moreover, enhancing the interpretability of genomic predictions can aid in the timely identification and interpretation of genetic variants, which remains a significant challenge in diagnostic laboratories (Ahmed et al., 2021). 5.3 Expanding biostatistical approaches to understudied populations Current genomic research often focuses on well-studied populations, leaving a gap in our understanding of genetic diversity across different human groups. Expanding biostatistical approaches to include understudied populations can provide a more comprehensive understanding of human genetic diversity and its implications for disease
