Scope and Usage
Genomic DNA is transcribed to RNA, but it is most common for transcripts to be recorded in databases using their complimentary DNA (cDNA) sequences. Therefore, the individual characters of a TranscriptReferenceSequence are the four DNA nucleotides: A,G,T,C.
A TranscriptReferenceSequence may correspond to either a coding or non-coding transcript. If the transcript is coding, the TranscriptReferenceSequence will link to a AminoAcidReferenceSequence.
TranscriptReferenceSequences may correspond to any transcribed sequence including, but not limited to a gene transcript, a pseudogene transcript, an alternately spliced transcript, a noncoding RNA, or a computationally discovered transcript.
Attributes
| Attribute Name | Attribute Type |
|---|---|
| codingRegionOffset | int |
codingRegionOffset: For transcripts that contain a coding region, codingRegionOffset specifies the index of the transcript sequence at which the coding region begins. It therefore provides a way to transfer between coding coordinates and transcript coordinates.

translation: For coding transcripts, the AminoAcidReferenceSequence that results in translation of the coding region.
