[bioontology-support] Question regarding MedDRA hierarchy viewing

Hello Lisa,

With the most recent version of MedDRA published through UMLS, our software has been unable to successfully traverse the hierarchy of the terms to arrive at the root terms. We have been unable to determine whether this is a software issue on our end, or a problem in the UMLS distribution, and so we were forced to remove the navigation tree from our system.

You can view and comment on the support ticket we are maintaining on this topic at; we appreciate receiving any observations from the community in this ticket.

I used to be able to view a MedDRA preferred term in the context of the MedDRA hierarchy, and therefore be able to map the preferred term to an System of Classification (SoC) term.  This seems to have been removed from the website, is this accidental or has this functionality purposefully been removed?

Thank you,
