Researchers at the University of South Florida have discovered the genetic biomarker that impacts age-related hearing loss. Professors Robert Frisina Jr., Robert Frisina Sr., and David Eddins have identified a gene that produces a protein in the inner ear which converts audio signals into a code the nervous system sends to the parts of the brain responsible for hearing. Summarizing the impact of this nine year study, Robert Frisina Jr. states the following:
“Age-related hearing loss is a very prevalent problem in our society. It costs billions of dollars every year to manage and deal with it. It’s right up there with heart disease and arthritis as far as being one of the top three chronic medical conditions of the aged...This gene is the first genetic biomarker for human age related hearing loss, meaning if you had certain configurations of this gene you would know that you are probably going to lose your hearing faster than someone who might have another configuration.”
Age-related hearing loss usually results in a gradual, high frequency hearing loss that can be worsened by loud noise exposure or other medical conditions such as diabetes. With this discovery, an individual can now be tested for the presence of this genetic marker. If the marker is present, an individual can take steps to lessen the degree and onset of age-related hearing loss by avoiding loud noise exposure or wearing ear protection.
