Figure 2: (a) Audiogram showing severe bilateral sensorineural hearing loss. Air conduction results are plotted with circles (O, right ear) and crosses (X, left ear). Bone conduction results are plotted with angle brackets (<, right ear) (>, left ear). Arrows represent no response to the loudest tone. (b) DNA sequence of the patient's GJB2 gene shows a heterozygous missense mutation c.175G > C (p.Gly59Arg) (red arrow), and the corresponding nucleotide in a control subject (arrowhead)
