     gahgu95av2CHR is an R object that provides mappings between a
     probeset identifier and the chromosome that contains the gene of
     interest.

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

     Each probeset identifier maps to a vector of chromosomes. If the
     chromosomal location is unknown, the vector will contain an 'NA'.

     Mappings were based on data provided by: Genecards (
     http://www.genecards.org ) on 2009-mag06
