Pedigree and audiological evaluation. a Pedigree of the family (Yonsei University Hearing Loss [YUHL] 30 family) is shown. Affected individuals are denoted by gray symbols, males are denoted by squares, and females are denoted by circles. The affected proband (30–22) was a 14-year-old female with low-to-mid frequency nonsyndromic hearing loss. b Pure-tone audiometry of the subjects is depicted. Frequencies (Hz) were plotted on the x-axis and the auditory threshold in decibels (dB HL) was plotted on the y-axis. Red circles refer to the right ear, and blue crosses refer to the left ear
