Genetic Research

The actual state of the research is that we are inviting participation from those with classic CMTC. The study involves providing a blood or saliva sample as well as a 3 mm diameter round skin biopsy. We plan to sequence both and look for differences. ~Dr. Millan Patel

Dr. Patel’s research study is currently on hold. We will provide status updates as we receive them.
