ESR1 Methylation data in breast cancer

[Lucas Porras]

Hi, 

My name is Lucas Porras, I am a MSc student from University of Montreal and I am currently working on ESR1 gene DNA Methylation. I have been able to plot a figure for my gene of interest.

However, there are multiple regions methylated for that gene, I was wondering if you know which specific region is methylated ffrom that plot (HM450) ?

Looking forward to your reply. 

Thanks in advance for your help.

Hi Lucas,

Thanks for reaching out!

Unfortunately we currently only capture methylation at the gene level, so we don't know the specific regions. If you look in the associated publication there might be more granular information available

Thanks,

Ino

Hi Lucas,

Just a little additional detail:

We pick one probe for each gene, based on correlation of the beta-value with the expression of the gene. See this FAQ item:

https://www.cbioportal.org/faq#which-methylation-probe-is-used-for-genes-with-multiple-probes

Unfortunately, we do not show the probe ID. You can however, dig up the original probe-level methylation data in the Broad Firehose data at this URL:

https://gdac.broadinstitute.org/

I hope this helps.

Niki.
