  for my $tv (@{ $tva->fetch_all_by_Transcripts([$transcript]) }) {

=head1 DESCRIPTION

This adaptor allows you to fetch TranscriptVariation objects either by the Transcripts
the associated VariationFeature falls in, or by VariationFeature directly. Storing
TranscriptVariation objects in a variation schema database is also supported. In the
database there will a separate row for each alternative allele of a TranscriptVariation, 
but the methods here will fetch all alleles associated with the TranscriptVariation
at once.
