Importance of standardisation: 

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

EUMORPHIA: 

EUMORPHIA 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

What is EMPReSS?: 

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

How was EMPReSS constructed?: 

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.

EMPReSS to date: 

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

Validation of the SOPs: 

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%

EMPReSS Database: 

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

EUMORPHIAPhenotype Ontologies: 

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

Developing ontologies - the centrality of the assay: 

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
