Editing Small interfering RNA (section)

=== Legal categorization and legal issues in a near future ===
Currently, SiRNA are currently chemically synthesized and so, are legally categorized inside EU and in USA as simple medicinal products. But as bioengineered siRNA (BERAs) are in development, these would be classified as biological medicinal products, at least in EU. The development of the BERAs technology raises the question of the categorization of drugs having the same mechanism of action but being produced chemically or biologically. This lack of consistency should be addressed.<ref>{{Cite journal |last1=Guerriaud |first1=Mathieu |last2=Kohli |first2=Evelyne |date=2022 |title=RNA-based drugs and regulation: Toward a necessary evolution of the definitions issued from the European union legislation |journal=Frontiers in Medicine |volume=9 |doi=10.3389/fmed.2022.1012497 |pmid=36325384 |pmc=9618588 |issn=2296-858X|doi-access=free }}</ref>
