Geneticist
Brigham and Women’s Hospital
Dr. Jun Shen is a Clinical Molecular Geneticist certified by the American Board of Medical Genetics and Genomics at Brigham and Women's Hospital. She is a fellow member of the American College of Medical Genetics and Genomics.
Dr. Shen’s clinical and research interests are focused on identifying genetic etiologies of hereditary disorders which include molecular genetic diagnosis and new gene discovery. She is Co-PI of the Hear-’n-SEQ program, one of the Gabriella Miller Kids First cohort studies, in which genome sequencing is applied to identify genetic causes of structural birth defects. She formerly was the co-investigator of the SEQaBOO project to investigate how to apply genome sequencing to newborn screen to improve care. Dr. Shen also serves on the ClinGen Expert Panel for Hearing Loss.
Dr. Shen
received her PhD from Harvard University, did her postdoctoral training at
Harvard Medical School and Howard Hughes Medical Institute, and completed the
clinical molecular genetics fellowship through the Harvard Medical School
Genetics Training Program.

Journal article
Mutations in the Presenilin (PSEN) genes are the most common cause of early-onset familial Alzheimer's disease (FAD). Studies in cell culture, in vitro biochemical systems, and knockin mice showed that PSEN mutations are loss-of-function mutations, impairing γ-secretase activity. Mouse genetic analysis highlighted the importance of Presenilin (PS) in learning and memory, synaptic plasticity and neurotransmitter release, and neuronal survival, and Drosophila studies further demonstrated an...
Journal article
Mutations in the Presenilin (PSEN1 and PSEN2) genes are the major cause of early-onset familial Alzheimer's disease (FAD). Presenilin (PS) is the catalytic subunit of the γ-secretase complex, which cleaves type I transmembrane proteins, such as Notch and the amyloid precursor protein (APP), and plays an evolutionarily conserved role in the protection of neuronal survival during aging. FAD PSEN1 mutations exhibit impaired γ-secretase activity in cell culture, in vitro, and knockin (KI) mouse...
