Our genes can predispose to many diseases. Is hearing loss among these?
The risk of various diseases is also influenced to a greater or lesser extent by our genes inherited from our family. They may also be at risk for hearing loss. Not only in congenital deafness, but at any age, the effects of genes can be expressed, making some more prone to hearing loss.
Out of a thousand newborn babies, 1-3 are born with some form of hearing loss, and every second between them can be traced back to genes. But not all genetic hearing loss occurs in infancy, it may be revealed in adulthood. Hearing loss can be a pure expression of genes, but it can be caused by the combined effect of genes and certain diseases.
The main diseases of genetic origin that cause hearing loss are Usher syndrome, Pendred’s syndrome, and an abnormal osteoporosis involving the inner ear called otosclerosis. But researchers are constantly identifying more and more genes that play a role in the development of hearing loss, so there is still much to discover in this area.
What is certain is that although genes may also play a role in hearing loss, environmental factors, high noise, and high volume can be responsible for the largest proportion of hearing loss and can also significantly affect our lifestyle. Therefore, it is important that we strive to protect our hearing at all ages and try to prevent it from deteriorating.
