If I knew then what I know now: The need for infrastructure to enable precision medicine

precision medicine - closing the infrastructure loop
For precision medicine to happen, we need to be able to close the loop when genetic discoveries are made.

Catherine Brownstein, MPH, PhD, is scientific director of The Manton Center for Orphan Disease Research at Boston Children’s Hospital. Kelsey Graber, MSc, is a research assistant in the Developmental Neuropsychiatry Program. Joseph Gonzalez-Heydrich, MD, is director of the Developmental Neuropsychiatry Program at Boston Children’s Hospital.

Research implicating rare genetic variants in medical and psychiatric diseases is quickly accumulating. This expanding knowledge should be taken into account when making treatment decisions for patients carrying these variants — as well as other family members — even when that knowledge comes after the patient is tested. But all too often, medical institutions are unable to go back and update the information given to families. We need a better infrastructure to enable precision medicine.

This problem recently surfaced in our psychiatry practice. It came to our attention because of a young boy with mild coordination delays and learning disabilities. At age 6, he started experiencing daily hallucinations such as voices telling him to kill his classmates.

The genetics of early-onset psychosis: Could it aid understanding of schizophrenia?

At age six, Matthew (not his real name) began hearing voices coming out of the walls and the school intercom, telling him to hurt himself and others. He saw ghosts, aliens in trees and color footprints. Joseph Gonzalez-Heydrich, MD, a psychiatrist at Boston Children’s Hospital, put Matthew, at age 9, on antipsychotic medications, and the hallucinations stopped.

It’s rare for children so young to have psychotic symptoms. Intrigued, Gonzalez-Heydrich referred Matthew for genetic testing.
