Anxiety disorders encompass generalised anxiety, panic disorder, and phobias. Heritability estimates range from 30–50% depending on the specific disorder.
How Genetic Is Anxiety Disorders?
Genetics plays a meaningful role in Anxiety Disorders, with heritability estimated at around 30%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Anxiety Disorders: COMT,SLC6A4,NTRK2. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Is Anxiety Disorders hereditary, meaning it's passed directly from parent to child?
Anxiety Disorders follows a multifactorial inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
