     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

_D_e_t_a_i_l_s:

     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:
