Figure 3. Audiograms of individuals with the p.Lys836Asn mutation in the WFS1 gene. The mean pure-tone audiograms of right and left ear in affected persons II:2 (age 60 and 85 years), III:2 (age 52 and 57 years) and III:3 (age 37 and 51 years) are depicted in panel A. Dotted lines and upward triangular symbols indicate first available and straight lines, and downward triangular symbols indicate last-visit mean audiogram. The mean age-related typical audiograms for DFNA6/14, adapted and modified from Pennings and coworkers [29], are depicted in panel B.
