Mouse version of 3q29 deletion: insights into schizophrenia/ASD pathways

Scientists at Emory University School of Medicine have created a mouse model of human 3q29 deletion syndrome, which is expected to provide insights into the genetic underpinnings of both schizophrenia and autism spectrum disorder.

In 3q29 deletion syndrome, a stretch of DNA containing several genes is missing from one of a child’s chromosomes. The deletion usually occurs spontaneously rather than being inherited. Affected individuals have a higher risk of developing intellectual disability, schizophrenia, and autism spectrum disorder. 3q29 deletion is one of the strongest genetic risk factors for schizophrenia, and the Emory researchers see investigating it as a way of unraveling schizophrenia’s biological and genetic complexity.

The results were published in Molecular Psychiatry.

“We see these mice as useful tools for understanding the parts of the brain whose development is perturbed by 3q29 deletion, and how it affects males and females differently,” says Jennifer Mulle, PhD, assistant professor of human genetics. “They are also a starting point for dissecting individual genes within the 3q29 deletion.”

Working with clinicians and psychologists at Marcus Autism Center, Mulle is leading an ongoing study of 3q29 deletion’s effects in humans, and observations from the mice are expected to inform these efforts. (More about Mulle here.) Read more
