Not main transcript selected by default?

[EugeneEA]

Hi, I annotated rsID rs121964985 (hg38, chr3:49417892)
and cravat outputed following gene and transcript:
AC104452.1 ENST00000636166.1

whereas in all_mapping filed it outputed

As far as I can understand the only MAIN transcript here is ENST00000273588
and the therefore the gene AMT and ENST00000273588 have to be prioritized in the current situation.

Why the output differ here?

Hi Eugene,

We just made an update to the hg38 mapper module to further prioritize the MANE transcript. If you update the module to version 1.10.3, you should see the correct transcript selected.

Hi, in the latest version it does work indeed! thanks!

Hi,

one more question concerning MAIN
the point is rs139416487
cravat returns as a primary transcript ENST00000240361.12
and all_mapping field:

{"TEX14": [["Q8IWB6", "p.Leu503Pro", "missense_variant", "ENST00000240361.12", "c.1508T>C"], ["Q8IWB6", "p.Leu497Pro", "missense_variant", "ENST00000349033.9", "c.1490T>C"], ["Q8IWB6", "p.Leu497Pro", "missense_variant", "ENST00000389934.7", "c.1490T>C"], ["", "", "NMD_transcript_variant,3_prime_UTR_variant", "ENST00000582740.1", "c.*1328T>C"]]}

But the MAIN here is ENST00000349033.9

Is it a bug or is there some logic behind it?

Best, Eugene
