Study: Genes Explain Only About 6% of Anxiety Disorder Development

The largest study of its kind on anxiety disorders has found that genetic variations explain only around 6% of anxiety severity. Anxiety manifests very differently in people, some experience it occasionally, while others struggle with serious symptoms that disrupt daily life. The research indicates that factors beyond genetics play a major role in the development of anxiety disorders.

A study conducted by an international team of researchers, the largest of its kind to date, has shed new light on the causes of anxiety disorders. The results show that, based on current data, genetic variations can explain only approximately 6% of anxiety severity.

Anxiety is a condition that manifests very differently from person to person. For some individuals, it may mean occasional feelings of tension, while for others it involves serious symptoms that disrupt daily life, impeding work, social interaction, and other activities. This diversity has long posed a challenge for researchers.

The study's findings suggest that the development of anxiety disorders is heavily influenced by environmental, psychological, and social factors rather than primarily by heredity. This means that based on genetic risk profile alone, it is not possible to make a reliable prediction about whether someone will develop an anxiety disorder or how severe it will be.

According to the researchers, this finding is an important step toward better understanding anxiety disorders, but it also underscores the need to view mental health conditions within a broader context. In the future, larger datasets and improved research methods may help identify more genetic factors associated with anxiety.
