TIMM8A and Mohr-Tranebjaerg syndrome: One novel hemizygous mutation, c.201delT (p.E68Sfs*11) in TIMM8A, was identified in a male proband D211 as a likely pathogenic mutation since similar truncating mutations p.E24* and p.R80* in TIMM8A have been reported to cause hearing loss associated with Mohr-Tranebjaerg syndrome [27].
