     ratCHRLOC15START maps LocusLink ids to the transciption starting
     locations of genes on chromosome number 15 corresponding to the
     LocusLink ids

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

     This is an environment object containing key and value pairs. Keys
     are LocusLink ids and values are the transciption starting
     location for genes. The starting positions for genes on both the
     sense and antisense strand are number of base pairs measured from
     the p (5' end of the sense strand) to q (3' end of the sense
     strand) arms. Values for the antisense strand have a leading "-"
     sign (e. g. -1234567).

     Values for keys are named vectors of length 1 derived from the
     smallest starting value found for the LocusLink id. Names of
     chromosome location values can be "Confident" when the gene can be
     confidently placed on a chromosome and "Unconfident" otherwise
     (denoted by "_random" in UCSC data).

     Mappings were derived from the following public data sources:
