Non-syndromic hearing loss is typically caused by recessive genes, meaning both parents are carriers of the gene. Some cases are caused by dominant genes, which means only one parent is a carrier.<\/p>\n<p>About 70 percent of cases of genetic hearing loss are non-syndromic, and 80 percent of these are caused by recessive genes.<\/p>\n<h2>Identifying Genetic Hearing Loss<\/h2>\n<p>Identifying <a title=\"genetic causes of hearing loss | journals.lww.com\" href=\"https:\/\/journals.lww.com\/thehearingjournal\/fulltext\/2020\/01000\/new_genetic_markers_of_age_related_hearing_loss.2.aspx\" target=\"_blank\" rel=\"noopener noreferrer\">genetic causes of hearing loss<\/a> can be tricky and sometimes requires the team of an otolaryngologist (ENT physician), audiologist, geneticist and a genetics counselor.<\/p>\n<p>The otolaryngologist may take a thorough history and physical exam, then make a referral to an audiologist for a <a title=\"\" href=\"https:\/\/sharphearingcenter.net\/hearing-info\/how-hearing-tests-work\/\">full hearing test<\/a>.<\/p>\n<p>The patient may also have lab work done to test for prenatal infections that can cause hearing loss in infants. Lab work can help confirm if any syndromes are related to the hearing loss.<\/p>\n<p>A geneticist and genetic counselor can help narrow down which syndromes are likely and eliminate ones that are not. Specific genes can be tested for further confirmation.<\/p>\n<p>If you or someone you love is suspected of having genetic hearing loss, there are options to find out the cause as well as a variety of treatments available.
