The Australian Phenomics Facility supports open access large-scale phenotyping of humans and mice to uncover the biological drivers in human disease.
The Australian Phenomics Facility specialises in the development, characterising and archiving of mouse models of human disease.
Established in 2004, the facility receives funding from the Australian Government’s NCRIS, Super Science and previously from CRIS through the Australian Phenomics Network and contributions from the Australian National University. The Animal Services Division receives funding support from JCSMR and the office of the DVCR. We have an experienced genomics and bioinformatics capability focussed on the identification of single nucleotide polymorphisms and the phenotyping capability to make the biological associations with probable human disease traits. Our goals are to firstly derive the underlying genetic mechanisms, and then look to extend this across the population and better understand cohort differences and responses.
We have an open access policy and support academic and corporate research programmes in Australia and internationally.
The facility is equipped with up to date technology ensuring the highest quality in all aspects of our work.
Our aim is to service research in a time efficient manner with quality performance targets through:
- Timely services
- Highly skilled technical staff
- Training and Development
- Consultation and planning
All services will be compliant with relevant legislation including those governed by the Office of the Gene Technology Registrar (OGTR), Animal Experimentation Ethics Committee (AEEC), Department of Agriculture and other relevant legislative authorities.
The human population harbours an enormous level of DNA sequence variation, recent data suggests that each person harbours an average of 12,000 protein-changing DNA variants spread over their genome. More than 300 of these variations 'knock-out' the protein they encode almost completely, while the rest change a single amino acid in the protein, with unknown consequences.
Mouse models are, and will continue to be, a powerful and appropriate tool available for obtaining physiologically relevant, experimentally based knowledge about the phenotypic consequences of DNA variants in human genes. Almost every human gene is matched by an orthologous counterpart in the mouse genome. However, unlike humans or any other mammal, the mouse is experimentally tractable. Large numbers of genetically identical mice can be bred quickly, and the tools available for manipulating the mouse genome are superior to those for all other organisms.
The research strategies
Whilst advances in technology and research are providing a steady stream of new gene targets for further research, a large section of the mammalian genome and its physiological significance remains to be uncovered. Phenotype driven discovery is complementary to gene driven discovery in that causative links between the genome and phenome can be made. Phenotype driven discovery begins with a phenotype of interest, rather than a gene of interest.
Through this phenotype driven approach, researchers can place the emphasis on a particular disease phenotype without any prior assumptions as to the genetic contributors to the condition. Libraries of gene-variant mice can be screened for a phenotype of interest, and through genomic technology, the causative mutation identified.
We have built upon our years of experience in phenotype driven screens to develop a comprehensive phenotyping pipeline to identify new pheno-variants. Researchers can register their interest in a phenotype of interest or work with our team of specialists to develop a customised screen.
Several large-scale international efforts* are currently underway to disrupt every gene in the mouse genome. Together with the avalanche of human data and research activity derived from human genome sequencing efforts, these developments place the mouse at the epicentre of functional genomics research.
We contribute to this effort through the production of libraries of gene-variant mice, each harbouring a collection of unique point mutations on a genome-wide scale. Through the use of whole exome sequencing capabilities, researchers can now access this collection of gene-variants through the single nucleotide variant (SNV) database.
Using this resource, researchers can now functionally validate and characterise mutations found in clinical cohorts in the controlled environment provided by mouse models. Multiple allelic variants of genes or pathways of interest can now be accessed and the effect of the mutations on the phenome characterised.
