Variation in clinical severity between similarly aged HL2 family members. (A) Three MYO7AG2164C individuals with mild hearing loss versus three MYO7AG2164C individuals with more severe hearing loss in the low and mid-frequency ranges. All six individuals are between the ages of 30-39 years old. (B) Two MYO7AG2164C teenage females showed marked differences in low and mid-frequency auditory thresholds. Auditory thresholds are shown for the right ears only. Responses between the right and left ears were symmetrical. Frequency in hertz (Hz) is plotted on the x-axis and hearing level in decibels (dB HL) on the y-axis. (C) Three MYO7AA1373T individuals between the ages of 31 to 41 years old from the Dutch N458I family demonstrate variation in their auditory thresholds.
