Phenotypes & Mutant Alleles
The Phenotypes/Alleles project in MGI enables access to spontaneous, induced, and genetically-engineered mutations and their strain-specific phenotypes.
Access Data
Search for mutations or QTL based on phenotype, human disease, mutation type, gene, or genome location.
Phenotypes, Alleles & Disease Models Query
Search for phenotype and disease associations by human and mouse genes and genome regions.
Human - Mouse: Disease Connection
Search for a phenotype term to find relevant mutant genotypes.
Mammalian Phenotype (MP) Browser
Browse for a human disease term to find mouse models.
Disease Ontology (DO) Browser
Search or browse for a human phenotype term to find relevant human diseases with those phenotypes.
Human Phenotype (HPO) Browser
Search for candidate genes for a given phenotype within a genomic interval.
Genes & Markers Query
Input a list of genes and retrieve associated alleles and phenotypes.
Batch Query
Submit data for alleles, mutants, transgenes, strains, or phenotypes.
Allele, Strain & Phenotype Submission Form

How do I...
.. find mutations in a specific gene? FAQ
.. find mouse models for a human disease or condition? FAQ
.. find mutations that cause a specific combination of phenotypes? FAQ
.. find all of one kind of allele (e.g. cre transgenes, LoxP/Frt-flanked alleles, etc.)? FAQ
