New research on gene mutation responsible for deafness shows it also causes heightened skin sensitivity

(Medical Xpress) -- Researchers have known since 1997 that mutations in the KCQN4 channel (a pathway that leads from the external environment to neurons) lead to progressive deafness and that the KCQN4 channel is only found in the hair cells in the inner ear, a part of the brain involved in hearing and oddly enough in skin cells. Now new research on the KCQN4 channel by a diverse group of scientists finds that the same gene mutation that causes people to go slowly blind also causes them to have increased sensitivity in their skin. They have published the results of their findings in Nature Neuroscience.
