Clinical Group Endophenotype Group Genetics and Stem Cell Group Molecular disturbances involving multiple genes contribute to the complexity of psychiatric disorders, requiring a focus on cellular and molecular changes. Advances in stem cell technology allow us to investigate specific molecular mechanisms underlying neuropsychiatric disorders and offer insights into genetic variations and their effects on neuronal functioning in neural cell models using induced pluripotent stem cells (iPSCs). This offers potential for improved diagnostic and therapeutic approaches.

Clinical Group Genetics and Stem Cell Group Endophenotype Group Endophenotypes are measurable and heritable traits or behaviors linked to a disorder, that sit between the genetic factors and the observable symptoms of the condition. Psychiatric disorders are increasingly viewed as neurodevelopmental disorders, which are influenced by genetic, epigenetic & environmental factors. These clues offer insights into genetic underpinnings of these disorders. Utilising endophenotypes derived from various assessments like neuroimaging can enhance the reliability of research on brain function. Dr. John P.
