hgu2beta7SYMBOL {hgu2beta7} | R Documentation

## Mappings between probe identifiers and gene symbols

### Description

When new genes are reported, gene symbols that are (hopefully) validated by an appropriate nomenclature committee are used to label the genes. hgu2beta7SYMBOL maps probe identifiers to the symbols used to report genes represented by the probe identifiers

### Details

hgu2beta7SYMBOL maps probe ids to either the official (validated by a nomenclature committee) and preferred names (interim selected for display). Efforts are bing made to differentiate the two.

Symbols typically consist of 3 letters that define either a single gene (ABC) or multiple genes (ABC1, ABC2, ABC3). Gene symbols can be used as key words to query public databases such as LocusLink.

Mappings were based on data provided by:

### Examples

        # Convert the environment to a list
        xx <- as.list(hgu2beta7SYMBOL)
        if(length(xx) > 0){
            # The symbols for the first two elements of XX
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
