A newly-identified mutation in the genomes of test mice could hold the key to a better understanding of progressive hearing loss, a human condition that is characterized by the loss of the auditory sensation in people exposed to single, very loud events or to constant powerful noises. Scientists discovered many genes that play a significant role in this affliction over the years, but its main causes were still believed to be environmental factors. Progressive hearing loss affects about 6 in 10 people aged above 70 and can lead either to hearing impairments or to complete deafness, depending on the rate at which the disease progresses. The main goal of this research is to further the understanding of the mechanisms that progressive hear loss uses to make the auditory sensation in humans fade out or disappear over the years. Hearing loss in children deserves special attention because of its significant impact on speech, development, and learning. For example, the audiogram on the left depicts a symmetrical hearing loss and the audiogram on the right depicts an assymetrical hearing loss.
The mutation, appropriately dubbed Oblivion, is thought to work similarly in both humans and mice. Now, researchers at the Wellcome Trust Sanger Institute in Cambridge, UK, found out that genetics could play a much more complex role in this degenerative condition than anyone previously thought. Professor Karen Steel, lead author of the new study, says that this discovery is important because it links the mutations of a gene known as Atp2b2 to the disease.

We showed that the mutant mice carried a change in one letter of their genetic code in a gene called Atp2b2. New ways of diagnosing and even treating the affliction could become available to doctors in the future, if other studies focused on the effect of Atp2b2 come up with viable ways of inhibiting the action of this gene.
Thus, an emphasis should be placed on early diagnosis and rehabilitation.Depending on the occurrence age, deafness may be prelingual (before development of speech) or post-lingual (after development of speech). Can be toxin or noise-induced, see links under “Pathology” on the menu and “hearing loss” under General public.How to identify hearing loss in childrenPost-natal screening for hearing loss depends on each country. Unilateral means hearing loss in one ear, with normal hearing sensitvity in the other ear. The fact that this gene is identical in mice and humans alike could open the door for further research on the matter. Changing a specific C to a T in this gene stops it from producing a normal molecular pump that is needed to keep hair cells in the ear working efficiently by pumping excess calcium out of the cell," Steele explained.
One gene, known as Connexin 26 (abbreviated CX26), is estimated to be responsible for half. Autosomal dominant mutations may present with post lingual progressive hearing loss with variable onset.
