    y Autism Spectrum Disorders (ASD)

    y ASD has a strong genetic component

    y Mouse models of ASD have given valuable insights

    y Mouse Genome Informatics (MGI) is the repository for

    mouse genomic data

    y phenotypic data represented by the Mammalian Phenotype

    ontology (MP)

    y 7961 MP terms annotated to >13,000 genes

    y Autism mouse models underrepresented in database

    Conclusionsy MP and other MGI annotations are a rich resource for integrated

    analysis for gene identification

    y Mouse strains with phenotypes similar to ASD models can find

    new ASD gene candidates or prioritize existing candidate genes

    y Approach is generalizable for sparsely characterized complex

    human genetic diseases

    y MGI lists 1,071 Human diseases with one or more mouse models
