Auditory brainstem response (ABR) recordings showed that Mir96+13G>A and Mir96+14C>A homozygotes exhibit profound deafness at all ages tested, showing no response at the highest sound level tested (95 dB sound pressure level (SPL)) at any of the ages studied (14 days to 6 months old) (Fig. 2). The gene discussed is MIR96; the disease is deafness.
