Alcoholism, Eye Color link? Study suggests alcohol dependency may be coded in ‘eye color’

Alcoholism linked to this eye color - Study

Eye color may be genetically linked to alcoholism, reports a new study by genetic researchers at the University of Vermont.

The study was published this month by doctoral student Arvis Sulovari and assistant professor Dawei Li in the American Journal of Medical Genetics.

The pair found that European Americans with light-colored eyes had a higher rate of alcoholism than those with dark eyes.

People with green, gray and brown eyes were also at higher risk of alcoholism, according to the study, than those with dark brown eyes.

The study outlined the genetic components that determine eye color and showed a correlation with the same chromosome that leads to alcohol abuse.

Researchers said they don’t know the reason for the relationship and added that more research into the topic is still needed.

The two worked with doctors and scientists in the Northeast to build a database of more than 10,000 people. Of those, most were African-American and European American diagnosed with at least one psychiatric illness.

Of those in the focus group, 1,263 were determined to be alcohol-dependent. The pair said they tested their hypothesis three times after noticing the correlation.

Sulovari and Li said they will continue their research on genetics.
