Epigenetics & Chromatin Clinic
The mission of the McKusick-Nathans Epigenetics and Chromatin Clinic is:
- To diagnose and provide optimal care for patients with either classical epigenetic disorders or mutations of the epigenetic machinery
- To learn from our patients some fundamental truths about epigenetics with the hope that this additional knowledge will lead to therapeutic development for our patients in the future
- To educate health providers and patients about epigenetics and the disorders of the epigenetic machinery
