     gahgu133bENTREZID is an R environment that provides mappings
     between manufacturer identifiers and Entrez Gene identifiers.

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

     Each manufacturer identifier is mapped to a vector of Entrez Gene
     identifiers. An 'NA' is assigned to those manufacturer identifiers
     that can not be mapped to an Entrez Gene identifier at this time.

     Mappings were based on data provided by:

     GeneCards database - www.genecards.org
