Anna Grzywacz

Anna Grzywacz is a Professor at the Independent Laboratory of Genetics and Behavioral Epigenetics within the Faculty of Medicine at Pomeranian Medical University in Szczecin. Her research focuses on genetic and epigenetic mechanisms underlying mental health disorders, substance use, and personality traits. Key areas include serotonin transporter gene polymorphisms (5-HTTLPR), dopamine receptor variants (DRD2), and the role of epigenetic modifications in addiction and behavioral traits.

Her work spans studies on alcohol use disorder, opioid receptor polymorphisms (OPRM1), and the genetic basis of athletic performance. She has published extensively in journals like International Journal of Molecular Sciences and Cells, analyzing gene-environment interactions and molecular pathways related to mental health. Collaborations with researchers like Suchanecka, Chmielowiec, and Trybek highlight interdisciplinary approaches to psychiatric genetics.

Grzywacz’s research integrates genetic epidemiology with clinical outcomes, exploring how genetic variability influences vulnerability to addiction, personality traits, and treatment responses. Her lab’s epigenetic studies on dopamine transporter genes (DAT1) and COMT gene polymorphisms further illuminate mechanisms behind reward-seeking behaviors and psychiatric comorbidities.
