New research on the neuroscience of anxiety explains more about the genetics of high sensitivity, even why we may experience shyness meeting people. This is from a press release:

Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological Association.

By showing that people who carry a common variation of a gene that regulates the neurotransmitter dopamine have an exaggerated “startle” reflex when viewing unpleasant pictures, the researchers offer a biochemical explanation for why some people find it harder to regulate emotional arousal.

Their sensitivity may, in combination with other hereditary and environmental factors, make them more prone to anxiety disorders.
