     hgu133aSYMBOL is an R environment that provides mappings between
     manufacturer ids and gene abbreviations.

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

     Each manufacturer id is mapped to an abbreviation for the
     corresponding gene. An 'NA' is reported if there is no known
     abbreviation for a given gene.

     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 Entrez
     Gene.

     Mappings were based on data provided by:
