\title{Map between Manufacturer Identifiers and Mendelian Inheritance in
  Man (MIM) identifiers}
\description{
  hgu133aOMIM is an R object that provides mappings between
  manufacturer identifiers and OMIM identifiers.
}
\details{
  Each manufacturer identifier is mapped to a vector of OMIM identifiers. The vector
  length may be one or longer, depending on how many OMIM identifiers the
  manufacturer identifier maps to. An \code{NA} is reported for any manufacturer
  identifier that cannot be mapped to an OMIM identifier at this time.
  
  OMIM is based upon the book Mendelian Inheritance in Man
  (V. A. McKusick) and focuses primarily on inherited or heritable
  genetic diseases. It contains textual information, pictures, and reference
  information that can be searched using various terms, among which the
  MIM number is one. 
  
  Mappings were based on data provided by: Entrez Gene  
  ftp://ftp.ncbi.nlm.nih.gov/gene/DATA
