Genotype

Objective:

Facilitate the use of the mouse as a model for human biology by furthering our understanding of the relationship between genotype and phenotype.

Gene detail page summarizes

information in MGI

Gene Expression Database (GXD)

• Most data obtained via manual curation

• Emphasis on embryonic expression data

• Assay types stored are:– In situ: RNA in situ, immunohistochemistry, reporter

gene (knock in)– Gels/blots: RT-PCR, Northerns, Westerns, RNase

protection, Nuclease S1– cDNA source data

Principles guiding curation of expression data

1. Different types of expression data are integrated

2. Expression patterns are described using controlled vocabularies

3. Context is provided by integration with other databases
