dbEST sequences were searched for the presence of the variant exon forms that were identified from cDNA sequences. An exon identified from cDNA sequences was considered to have an EST hit when at least one EST from dbEST contained some form of that exon. If all the variant forms were present in the EST data, the exon was considered “confirmed”
