What is a wild card?
A wild card is an alphanumeric character or set of characters that can stand for a wide range of other characters. On most of the MGI Query Forms, you can use the * (asterisk) as a wildcard to facilitate text field searches.
For example, do this:
- Enter Acr* in the Symbol/Name box on the Genes and Markers Query Form.
- Click the Search button at the top of the form.
The Genes and Markers Query Results -- Summary page contains links to any markers whose symbol begins with Acr, such as Acr, Acrbp, and Acrv1. Note that there is also a link to Adp because its gene name is acrodysplasia.
