EYA4 and deafness: Our study also expands the genotypic spectrum of EYA4 in DFNA10, by adding four novel variants (c.697C>T:p.Gln233Ter, c.208+1del, c.578dup:p.Tyr193Ter, and c.1468G>T:p.Glu490Ter), all of which were associated with moderate to severe non-syndromic deafness characterized by gradual hearing loss.
