Pure tone test of the AIFM1-positive cases. (a) Average threshold of the 50 cases with AIFM1 variations. (b) Mean PTA in the groups with different disease courses. (c) Mean PTA in the groups with different onset ages. (d-f) Mean threshold in each frequency with different follow-up periods. dB: decibels; Hz: Hertz; PTA: pure tone average.
