As GRIN grows, we exponentially gain greater insights from you as patients to help accelerate therapies for Charcot-Marie-Tooth (CMT) and Inherited Neuropathies. This is an incredible opportunity for you to participate in CMT and Inherited Neuropathies Patient-Focused Research.

Your vital data allows for researchers to study why individuals experience different symptoms and address what is most important to patients when thinking about drug development. Scientists can also learn how a particular mutation type may lead to different or unique symptoms helping us to develop treatments for all types of CMT and Inherited Neuropathies.

By completing your profile, your de-identified information will be utilized to advance research and support clinical trial designs. As a registrant, you will be informed when you may be eligible for clinical trials.

These Patient-Reported Outcomes Studies will enhance therapy development in collaboration with our industry partners. By informing Healthcare Providers and others with your critical data, we can work to improve diagnosis and enhance patient care.

Anyone diagnosed with CMT or other Inherited Neuropathies can join GRIN. Your information is always kept confidential: only approved research investigators and industry partners can see your de-identified information.

If you are already a participant, we still need you! It’s important to update your profile and participate in many of our Patient-Reported Outcomes Research Studies.

With all of the current positive research momentum, there is no better time than right now to join GRIN! Become a part of the effort to find the treatments and cures for all Inherited Neuropathies!
