If you add the "Ensembl Exon ID" attribute to your query, you will get the exon stable ID in the header (please see attached screenshot1).<br>
<br><div>For this example you will get the following back:<br>>GRM3|ENSG00000198822|ENST00000546348|ENSP00000444064|ENSE00000700691;ENSE00002307238;ENSE00003523712;ENSE00002052628|2;4;3;1|1416<br><br>In this example the Exon rank is the following in the sequence header:<div>

<div><br>Biomart won't return the Exon stable ID in the rank order but the "Exon Rank in Transcript" attribute will help you know the actual Exon rank order.</div><div><br></div><div>2) The "Constitutive Exon" attribute in biomart correspond to the Exons that are not spliced out, therefore present in all the Transcripts of a given gene (please see: <a href="http://www.ensembl.org/Help/Glossary?id=471" target="_blank">http://www.ensembl.org/Help/Glossary?id=471</a>).</div>
<div>I am sorry, I can't see the "Ensembl Exon ID" in your screenshot. Could you please send me a screenshot of the result page or the Exon stable ID?</div><div><br></div><div>The "Structure" section can help you to see if an Exon is constitutive or not (please see last column of the attached screenshot2). </div>

In this example, I wonder what order, it is correct to assume that 2;5;4;3;1 refer to some indices of the exons as defined based on the canonical transcript? but what is the meaning of this unordered indices here for this particular transcript?<br>
