Electric Currents in Nerve Cells

Amy Lee, PhD, discusses her lab's research on electric currents in nerve cells, which play a part in severe disorders such as deafness, blindness, epilepsy, and migraine.

New test can screen all deafness genes simultaneously

Pinpointing the exact genetic cause of inherited deafness has always involved sequencing one gene at a time, a process that can take up to a year and cost roughly $1,000 per gene. It would cost around $75,000 to test all known deafness-causing genes using this approach.

Study finds new role for protein in hearing

University of Iowa scientists have discovered a new role for a protein that is mutated in Usher syndrome, one of the most common forms of deaf-blindness in humans. The findings, which were published Aug. 8 in Nature Neuroscience, may help explain why this mutation causes the most severe form of the condition.
