Dr. Kate Tatton Brown
Kate, as part of a team of scientists and clinicians, first discovered DNMT3A gene alterations as a cause of an overgrowth-intellectual disability syndrome in 2014.

I am committed to working with families so we better understand TBRS and to ensure the very best care is provided for children and adults with TBRS across the world..
