The purpose of this project is 1) to update the molecular biology capabilities of the DART laboratories and 2) determine if genetic factors can be determined which identify workers who have an increased susceptibility to noise-induced hearing loss. Partnering with the Department of the Navy, volunteers will provide biological samples which will be tested for genetic variation of seven pre-selected genes. These genes have been shown to code for proteins important for hearing. This project is based on seed money provided by the National Office of Public Health Genomics and will end on September 30, 2009.
The ultimate goal of this research is to reduce the incidence of NIHL by integrating genetic tests into worker safety programs. This would allow susceptible workers to receive additional resources (e.g. advanced training, high-tech hearing protection or additional monitoring) to reduce the occurrence of NIHL.
This effort will be successful if the resulting publications result in further research into the genetic bases of individual susceptibility to noise-induced hearing loss. These efforts should be measurable in citation reports.
In 2005 the NIOSH Hearing Loss Prevention Program under went peer review by the National Academies of Science Institute of Medicine. The peer review report was issued in 2006 recommended that Strategic Plan be developed for the Program. In 2007 the Program issued a Strategic Plan which included Intermediate Goal 5.2. "Prevent hearing loss by understanding individual susceptibility to noise." This project specifically addresses this Intermediate Strategic goal. By understanding factors which influence susceptibility to hearing loss, professionals can target interventions to reduce the burden of hearing loss by additional worker training, innovative technology and frequent audiometric follow up.
