3 Importance of standardisation Better reproducibility of test outcome Better comparability of test outcome Sharing of phenome results Reduction in the number of mice used in research

4 EUMORPHIA European Union Mouse Genetics Research for Public Health And Industrial Applications Phenotyping  Working groups to develop and standardise primary and secondary phenotyping protocols for all body systems  To develop them in collaboration with other centres throughout the world and in consultation with clinicians, human geneticists, physiologists and informaticians

5 Phenotyping - Workpackages  Standardisation - animal handling  Clinical Chemistry/Haematology  Renal systems  Central, peripheral nervous system, muscle  Behaviour and cognition  Imaging  Necropsy, pathology, histology  First-line phenotyping  Cardiovascular  Hormonal/metabolic  Allergy and infection  Sensory systems  Pulmonary  Cancer  Bone, Cartilage  Expression analysis European Mouse Phenotyping Resource for Standardised Screens - EMPReSS

6 What is EMPReSS? European Mouse Phenotyping Resource for Standardised Screens The EMPReSS provides a platform for the systematic and standardised primary characterisation of mouse mutant models It is a comprehensive database of validated SOPs for systematic screens and tests that allows us to describe the phenotype of a mouse

8 How was EMPReSS constructed? The SOPs are categorised according to the experience required and the amount of specialised equipment. The primary tests are divided into:  Primary - for those tests that are simple to apply and require little specialist equipment  Primary extended - which give further information on the phenotype, but require more specialised skills or equipment.

9 Working groups established SOPs discussed and drafted Validation between centres Discussion of validation results Revision of SOPs Revalidation between centres Additional validation between centres Review of SOPs by EMPReSS resource team Review and sign-off by Eumorphia scientist outside working group

10 BALB/cByJ (+ BALB/cAnN) AnN ENU mutagenesis at Harwell C57BL/6J (+ C57BL/6N) C3H/HeBFeJ (+ C3H/HeN) FeJ ENU mutagenesis at GSF/HeN at Harwell 129/SvPas (+ 129S6/SvEvTac) Inbred strains for validation

11 EMPReSS to date WP groups established March 2003 All relevant WPs have contributed A total of 161 SOPs, both primary and primary extended, have been submitted and accepted by EMPReSS along with annexes

12 Validation of the SOPs The SOPs are subjected to evaluation by one or a number of the partners. The validation levels are given at the top of each SOP Validation by testing on selected inbred mouse strains and/or selected mutants at one EUMORPHIA laboratory Validation by testing on selected inbred mouse strains and/or selected mutants at two EUMORPHIA laboratories Full comparison of results of testing on selected inbred mouse strains and/or selected mutants at more than two EUMORPHIA laboratories 35% 44% 21%

23 EMPReSS Database SOPs engineered for XML format Links between SOPs and baseline phenome data - EuroPhenome database –assisting validation, EMPReSS evaluation and SOP development EMPReSS will allow systematic integration of the ASSAY with phenotype ontologies

24 EUMORPHIA Phenotype Ontologies Informatics  We need to develop systematic and comprehensive systems to describing phenotypes - phenotype ontologies  Phenotype ontologies will be central to the development and mining of comprehensive animal phenotype databases  Integration with SOPs - the assay is central to the development of ontologies An ontology is an explicit formal specification of the terms in a domain (concepts) and the relationships (attributes) amongst them

25 Developing ontologies - the centrality of the assay CONCEPT {has_attribute} ATTRIBUTE {characterised_by} ASSAY {has_value} VALUE e.g. Eye {has_attribute} Colour {characterised_by} Visual Inspection {has_value} Brown or Mouse {has_attribute} Body Position {characterised_by} SHIRPA {has_value} Flat All phenotypes are the result of an assay

26 Building international standards Examine with our partners EMPReSS as a model to develop an international repository for SOPs and baseline data Discussions with developers, managers and users of other related resources worldwide October 2005
