_D_e_s_c_r_i_p_t_i_o_n:

     NCBI partitions sequences submitted to GenBank into non-redundant
     sets of clusters. Each cluster contains sequences that represent a
     unique gene and is assigned a unique UniGene id. hgu2beta7UNIGENE
     maps probe identifiers to UniGene cluster identifiers for genes
     represented by the probe ids

_D_e_t_a_i_l_s:

     A UniGene id represents a cluster of sequences of a gene. Using
     UniGene ids one can query the UniGene database for information
     about the sequences or the LocusLink database for information
     about the genes.  

     Mappings were based on data provided by:
