Mutated muscle protein can cause deafness: Gene mutations on X chromosome lead to progressive hearing impairment
Welcome once more to ItexMall Health and Fitness, where you can enjoy reading another fascinating snippet of Health news right here:
Excessive noise is not the only thing that causes damage to hearing. In many cases, genetic factors are responsible for the loss of hearing at a young age. Researchers have discovered a previously unknown genetic cause of progressive hearing impairment: the disease is caused by mutations of the SMPX (small muscle protein) gene, which is located on the X chromosome. It was not previously known that this gene, which is active in the skeletal muscle and heart, also plays a role in hearing. The discovery will make it easier to diagnose progressive hearing impairment and may also provide a starting point for the development of new treatment methods.
