Audiologic features of DFNA6/14/38 subjects from family W21-1472. (A) The pure tone air conduction thresholds in dB HL of 0.25 to 8 kHz of all subjects identified with the WFS1 (c.2512C>T p.(Pro838Ser)) variant (III:02, III:04, III:11, III:13, III:25, III:27, IV:03, IV:07, IV:09, IV:13 and V:04) and subject V:01 who was not genetically tested. Black lines with circles represent the right ear, black lines with crosses represent the left ear, grey lines and dots represent the age- and gender-specific 95th percentile. (B) Mean audiogram with a 95% confidence interval. (C) Age-related typical audiograms (ARTA), derived from cross-sectional linear regression analysis of the most recent audiograms of DFNA6/14/38 subjects. Each line represents a ten-year age span. dB HL, decibel hearing level; f, female; kHz, kilo hertz; m, male; y, years.
