Family and twin studies estimate recurrence risk and heritability, showing that anxiety disorders aggregate in families and have a moderate genetic component. Linkage studies identify chromosomal regions that may harbour risk-related genes, while association studies, including genome-wide association studies, investigate common, structural, and rare genetic variants across the genome. Gene-environment interaction studies examine how genetic vulnerability is shaped by environmental exposures, and molecular, cellular, and clinical studies help translate genetic findings into biological mechanisms and potential therapeutic targets.
