Figure 3. Audiometric results of patients who are homozygous for the USH1C c.1220delG mutation.

Figure 3

A. Patient MOL0486 II:3 (13 yo) with normal hearing function. B. Patient MOL0887-3 (44 yo) with severe SNHL, particularly at higher frequencies (descending pattern). C,D. Hearing threshold versus age at a frequency of 4,000 Hz (C) and 8,000 Hz (D). At younger ages, normal hearing function is evident, but after the age of 40 years, sensitivity is markedly reduced. For each of the 10 patients, the data from both the right and left ears is presented, showing symmetry between both ears.
