Finding 3: The University of Western Australia notes that that the definitions in the Gene Technology Act 2000 and Regulations 2001 are difficult to maintain and regulate in a rapidly changing environment. Furthermore, the social and ethical issues surrounding these definitions create a challenging environment. We would like to voice our support for the changing of the definitions, while noting that our response to the option paper called for a balanced approach to be taken. Specifically, that the regulations should be based upon a logical and risk based analysis of the outcomes that are produced, rather than a regulation based on process. In addition, as noted by us, the main advantage of this option is that it will result in the GMO-classification and regulation of SDN-3, ie the insertion of long stretches of foreign DNA into the genome. At the same time, this option rules out short oligo-directed repair (SDN-2), as well as non-homologous end joining (SDN-1) from GMO classification and regulation.
From a scientific perspective, it is possible for any of the SDN approaches to significantly alter the phenotype of the organism; with potentially harmful effects should the organism be released. However, from a practical perspective SDN-1 and SDN-2 will induce changes that could occur naturally and will in each case produce very small-scale localised mutations. Although mutagenesis by random transposition does create GMOs, mutagenesis by chemical mutagens are not classified as GMOs even though this has the same outcome as SDN-1 and SDN-2 (ie random point mutations and small indels). Therefore it would be illogical to exempt mutageneses by chemical mutagens from the GMO definition, yet include SDN-1 and SDN-2 approaches. If, at a future date, ‘mutagenesis’ was to be re-classified as creating a GMO, then SDN-1 and SDN-2 could also be included in the mutagenesis category. This needs further clarification as mutagenesis by transposition does create GMO mutants, while EMS mutagenesis does not.
At present, the regulatory burden for standard GMO experiments is not onerous. Thus, adding SDN technology to the existing framework should not be problematic. This committee would caution against future new regulatory burdens, for example the requirement of whole genome sequencing for every GMO organism created in a laboratory setting (eg. Mammalian Cell lines, plants, mice). There should be a progression of regulation as an organism moves closer to potential application or use as a product. Once a milestone is passed along this pipeline, then perhaps at that point a full genome sequence for the organism could be performed as a form of due diligence before progressing to the next stage of regulation.
Finding 4: The University of Western Australia agrees that synthetic biology is and should remain within the scope of the scheme, and supports the ACOLA review of the regulation.
Finding 5: While UWA supports removing any reference to human beings being within the scope of the scheme, we ask that caution be exercised. This should be independent of human cell lines, and independent of research on human embryos, and should only be referring to entire human beings as per the Research Involving Human Embryos Act 2002. Further, the University asks that the question of who shall be responsible for the regulation of this research should be looked at carefully. We suggest that the NHMRC has the ethical capacity to examine this most effectively, but that technical skill should also be sought, perhaps from the OGTR.
Findings 6 and 7: UWA again would suggest that a risk based approach would be most logical in this instance. The purpose of the GM production should not influence the category or the regulatory controls. All regulations should be based upon a logical and risk based analysis of the outcomes that are produced, rather than a regulation based on process or intention of the research.
