Susan Kuo Explores Genetics in Schizophrenia and Autism: A Researcher’s Journey to Unlock Neuropsychiatric Mysteries

Unlocking the Mysteries of Neuropsychiatric Disabilities: One Researcher’s Journey

Growing up in Vancouver, Susan Kuo witnessed a family member’s transformation from warmth and affection to suspicion and withdrawal. At the time, she didn’t understand the changes. It wasn’t until she took psychology classes as an undergraduate at the University of British Columbia that she recognized the signs of schizophrenia. That realization brought clarity to a confusing chapter of her life—and set her on a path to help others navigate the complexities of neuropsychiatric disabilities.

“If we had been able to figure out more specific services earlier, that would’ve been really helpful in terms of getting my family member back on track,” said Kuo, now a postdoctoral researcher studying autism and schizophrenia at the Center for Genomic Medicine and Department of Psychiatry at Massachusetts General Hospital. She is also affiliated with the Stanley Center for Psychiatric Research at the Broad Institute.

Kuo’s fascination with medicine and psychology led her to pursue a Ph.D. in clinical psychology at the University of Pittsburgh, where she focused on schizophrenia. Her work aimed to uncover how genetic factors influence brain and behavioral changes across a person’s lifespan.

Uncovering Developmental Patterns

Schizophrenia typically emerges in young adulthood, between the ages of 18 and 25—a pattern Kuo observed in her own family. She wondered whether biological relatives of people with schizophrenia showed subtle differences in cognition or brain structure that might hint at genetic predispositions.

“First-degree relatives, siblings and such, share on average 50 percent of their genes in common with a person with schizophrenia,” explained Michael Pogue-Geile, Kuo’s Ph.D. adviser.

Kuo and Pogue-Geile divided relatives of people with schizophrenia into three age groups: pre-20s, 20s, and post-20s. Their research revealed that relatives in their 20s who carried more schizophrenia-associated genetic variants showed subtle differences in cognitive function and brain structure, even without a diagnosis.

The findings suggest that genetic effects contributing to schizophrenia may become more pronounced during young adulthood, a time of significant change and stress. “That was very innovative research that not really any other people had done in the field,” Pogue-Geile said.

Predicting Intervention Responses

Kuo’s work also explored how people with schizophrenia follow different developmental trajectories. Some maintain social ties and academic performance, while others show progressive challenges leading up to their first episode. A third group struggles with social and academic difficulties from childhood.

Her research found that those in the third group showed the most improvement with cognitive training interventions. “If we can intervene successfully at the beginning of this illness, the hope is that we can change the trajectory,” said Keith Nuechterlein, director of the UCLA Semel Institute of Neuroscience and Human Behavior.

Building Clinical and Educational Resources

Now at Massachusetts General Hospital, Kuo is expanding her research to include autism. She aims to understand how genetic and phenotypic variations evolve over time, with the goal of improving clinical and educational resources.

“Heterogeneity in autism is massively underdiscussed, which has implications for clinical practice and family experience,” said Elise Robinson, an epidemiologist and geneticist who supervises Kuo’s research.

Kuo’s team analyzed early developmental milestones, such as walking and talking, in over 17,000 autistic children compared to 4,000 siblings without autism. They found that while some autistic children reached milestones on time, others experienced delays of up to 20 months.

Building on these findings, Kuo’s team is developing online resources for clinicians and families to navigate the latest genetics research and clinical testing options.

“By understanding the genetic and phenotypic diversity, the hope is that we can better match different services to folks who could use them,” Kuo said. “What are the supports they could use down the line as you’re anticipating some of the challenges—or some of the strengths—they might develop?”

Robinson praised Kuo’s dedication and leadership. “She’s incredibly diligent, invariably thoughtful, and nonjudgmental,” Robinson said. “It’s a large part of why she’s such a natural leader, an obvious budding leader in our community.”

Through her work, Kuo continues to bring clarity and hope to families navigating the complexities of neuropsychiatric disabilities—just as she once sought for her own.

Conclusion
