Genetic hearing loss is a type of hearing impairment caused by changes in genes. It can be inherited from one or both parents and may occur at birth or develop later in life. This condition can affect the ability to hear sounds of different frequencies and volumes, impacting communication and quality of life. There are various genes associated with genetic hearing loss, such as GJB2, which is linked to non-syndromic hearing loss. Genetic testing can help identify the specific cause, allowing for better management and support options for those affected by this condition.
