\title{Pseudoautosomal region base positions}
\description{
  Pseudoautosomal region (XTR, PAR1, PAR2) base positions for the X and
  Y chromsosomes from the GRCh36/hg18 and GRCh37/hg19 genome builds.
}
\usage{
pseudoautosomal.hg18
pseudoautosomal.hg19
}
\format{
  A data.frame with the following columns.
  \describe{
    \item{\code{chrom}}{chromosome (X or Y)}2
    \item{\code{region}}{region (XTR, PAR1, or PAR2)}
    \item{\code{start.base}}{starting base position of region}
    \item{\code{end.base}}{ending base position of region}
  }
}
\details{
  The XTR region on X is defined as DXS1217 to DXS3.
  The XTR region on Y is defined as SY20 to DXYS1.
