Abstract:The rapid advancements in genomic sequencing technology have led to the emergence of a commercial testing industry and the generation of vast amounts of personal genomic data . The sharing of personal genomic data has become a crucial means for testing companies to gain profits, and is also a fundamental element in advancing genomics research and pharmaceutical product development. However, in China, the current legal regulations governing genomic data often overlook its unique characteristics, leading to significant challenges. Specifically, genetic testing companies are able to frequently secure informed consent from consumers with relative ease, allowing them to gain ownership or control over personal genomic data through invalid anonymization measures. This regulatory gap poses serious risks at multiple levels—individual, group, and national—resulting in an unequal distribution of benefits and imbalances in the obligations for risk prevention and control. In order to facilitate the sharing of personal genomic data and mitigate multiple risks, the principle of balancing interests should be introduced. This principle would enhance the informed consent process, ensuring that the benefits derived from genomic data sharing are primarily employed to mitigate the multifaceted risks associated with such sharing. On this basis, improving the mechanism for genomic data sharing can help establish comprehensive lifecycle management for genomic data, promote its sharing, eliminate associated risks, and protect the rights of data subjects. This will further drive scientific and technological innovation and industry development in the field of genomics.
