Congrats to Jessica Christiansen of the Penzes Lab, who was awarded 2nd place in the Basic Science category at Northwestern’s Research Day. Her research on KALRN advances our understanding of neurodevelopmental disorders, including ID, schizophrenia, and autism.

“About 80% of this increase is caused by broader diagnostic criteria... but 20% is not explained by this,” said Dr. Peter Penzes (@Penzes_Lab), director of @NUAutism, on the rise in #autism diagnoses over the past decade, in an interview with @wttw. tinyurl.com/muaty8cb

New research from the Penzes lab!
We found schizophrenia risk factor 16p11.2 duplication to cause profound alterations in excitatory iPSC-derived neurons. These effects were present in schizophrenia patient-iPSC, revealing potential pathophysiology.
