The LHON Conference takes place in conjunction with the UMDF's Symposium.  On April 2, the UMDF updated its website with the following announcement.   

"As the world closely follows Coronavirus (COVID-19) pandemic, we are taking all necessary precautions to safeguard the well-being of our mitochondrial medicine community.

The safety and well-being of our attendees has been our top concern in planning the June symposium.  With travel bans extending into the summer months for our scientific/clinical community, we made the difficult decision to cancel the in-person Mitochondrial Medicine 2020 symposium at the JW Marriott Phoenix Desert Ridge Hotel and Resort.  

Our team is working to put together a virtual scientific and family program in the coming months.  Please check back here or stay in touch and follow us at ,, and

Hotel Reservations: You should be receiving a cancellation from the Marriott regarding your hotel reservation.

Please know that we are always here for you during this unprecedented time. For the latest information on the coronavirus (COVID19) and its impact on patient families, please visit

Please mark your calendars for June 23-26, 2021 for UMDF Mitochondrial Medicine 2021: Charlotte, NC.
We look forward to celebrating UMDF’s 25th Anniversary with you in Charlotte!"
