Hi,

Recently I tried to retrieve mitochondrial DNA mutations from cBioPortal, but I kept coming across the same error saying that the gene symbols I entered were invalid (e.g. MT-ND1).

May I know if this is a temporary glitch, or mitochondrial DNA data has been removed from the database?

I'd really appreciate your response.

Many thanks and best regards,
Eng Wee

Hi Eng Wee,

Thank you for reaching out. This isn't a glitch, mitochondrial DNA-encoded genes (like MT-ND1, MT-ND2, etc.) are currently not supported in cBioPortal, so they will show up as invalid symbols.

Hope this helps! Let us know if you have any other questions.

Best,
Ramya
