Simple Search

1. Enter an expression into the search field on the GeneCards homepage and
   choose one of these to search by:
   
   
   • Symbol only - Brings up the GeneCard for the specified symbol. This is done by selecting the Symbol only button and typing the requested gene symbol in the search box.
      
   • Symbol/Alias - Searches the database for a gene name, or its alias. This is done by selecting the Symbol/alias button and typing the requested symbol or alias for the gene in the search box.
      
   • GCid - the Id given to the gene by GeneCards (determined by the GeneLoc Algorithm).
     A gene can be searched by its GCid by selecting the GCid button and typing the requested Id in the search box.
      
   • External Id - A gene can also be searched by an External Id (accessions from HGNC, EntrezGene, UniProt, and Ensembl). This is done by selecting the External Id button and typing the requested Id in the search box.
      
   • Keywords - Searches the database in a full free text search. This is done by selecting the (default) keywords button and typing any kind of text relevant to the search in the search box.

   * In the first four cases a use of a wild card (*) results in retrieval of a list of symbols.
   * A use of space in the search string automatically results in a Keywords Search
     (see Search Examples for more on multiword searches).
   * The GeneCards search is case insensitive.

2. Check whether you would like to change the default settings of Search Options.

3. Click the "Go" button to start the search.

Example of a keyword search: diabetes AND tongue

Advanced Search

Advanced search enables you to browse GeneCards for more specific results. A broader variety of search options is offered in order to focus the search.
There are two ways to use Advanced search:

1. Click the Advanced search link next to the search box at the GeneCards homepage - a new page with more search options appears.
   Type the search string in the search field, and ask for the search to be performed within a specified:

• Card Category - only genes of the specific card category chosen from the list box would be displayed.

• Symbol/id - only genes with the symbols/ids typed in this box would be displayed.*

• Symbol/id from file - search on a user defined subset of cards by uploading a file of the symbols/ids for the cards that you wish to peform a search on.

Perform a simple search, and improve the search after getting the results - above the MicroCard list, there is a scrollable list of all found gene symbols. Delete the ones you are not interested in and choose the button you want to click:

• Search within results - the symbols/ids list under the search box updates, and you can perform a more specific search.

• GeneALaCart - Opens the query page of the batch queries service, loaded with the list of gene symbols found by the original query. You can then perform a GeneALaCart query to create a file of GeneCards annotations for your list of genes.**

• Genomica - forwards the found genes to Genomica for further analysis and visualisations.

** To use GeneALaCart you must be a registered user.
    To register click the GeneALaCart link on the GeneCards homepage.

What Do I Get?

There are 3 types of cards in GeneCards:

• MicroCard - Displayed on the search result page. Provides the symbol, GCid, and short description of a gene.
  The MicroCard list can be sorted alphabetically (default), or by relevance (determined by the relevance scoring method). The sorting options appear on the GeneCards homepage.

• MiniCard - Displayed after the MicroCard list. Specifies the gene name, gene description, GCID, and the text lines in which the search term occurs. Also provides the chromosomal location of the gene.
  Note: in some cases the search term might not be shown on the web page.
  The MiniCard list is sorted by relevance (determined by the relevance scoring method).

• GeneCard - A profound display of all the data concerning a specific gene, including relevant links to other important websites.

Search Examples:

I.   Simple Search:

Search String:	Matching Words:	Search Description:
brca1	brca1, BRCA1	Exact word match (case insensitive).*
x84746	x84746	GenBank accession number
Hs.1288	Hs.1288	UniGene cluster
image:303124	IMAGE:303124	Clone identifier

* A Keyword Search would result in a list of MicroCards and MiniCards.
  A Symbol Only Search would result in the GeneCard itself right away!

II.   Wild Card Search (*):

This type of search will usually give out a large number of results.

Search String:	Matching Words:	Search Description:
live*	live, lives, liver	Any object that begins with the string "live"
*gammaglob*	agammaglobulinemia, hypergammaglobulinemia, hypogammaglobulinemia, gammaglobulin therapy	Any object that contains the string "gammaglob"

III.   Multiword Search:

Search strings of more than one word are searched for as one single phrase, unless "AND" or "OR" are used (see examples below).

Search String:	Matching Words:	Search Description:
obesity diabetes	obesity diabetes	Regards these words as one single phrase (compare the AND/OR searches below!)
obesity AND diabetes	preponderance of insulin resistance, diabetes mellitus ... genetic predisposition to obesity	All strings must exist in the GeneCard (unlike the example above, here the words don't have to necessarily follow each other)
obesity OR diabetes	obesity, diabetes	At least one of the strings must exist in the GeneCard (notice the difference from the AND search!)
neurodegenerative or senile and Alzheimer	...senile dementia of the Alzheimer type: relation with the cognitive state and with quantitative studies of senile plaques...	Corresponds to "(neurodegenerative or senile) and Alzheimer"

IV.   Advanced Search:

This type of search is useful for getting a short list of very specific results.

Search String:	Show only:	Matching Words:	Search Description:
asthma	Gene Type: protein-coding	asthma, ASTHMA	Exact word match in the relevant gene type only (case insensitive)
asthma	Symbols/ids: ADRB2, ALOX5, HNMT	asthma, ASTHMA	Exact word match in the specified genes only (case insensitive)
