\description{
  \code{VariantType} subclasses specify the type of variant to be located with
  \code{locateVariants}.

\usage{

    FiveUTRVariants()
    ThreeUTRVariants()
    SpliceSiteVariants()
    IntergenicVariants()
    AllVariants()
}

\details{
  \code{VariantType} is a virtual class inherited by the \code{CodingVariants},
  \code{IntronVariants}, \code{FiveUTRVariants}, \code{ThreeUTRVariants},
  \code{SpliceSiteVariants}, \code{IntergenicVariants} and \code{AllVariants}
  subclasses.

  The subclasses are used as the \code{region} argument to
  \code{locateVariants}. They designate the type of variant (i.e., region of
  the annotation to match) when calling \code{locateVariants}. The subclasses
  themselves have no slots and require no arguments for an instance to be created.
