TMPRSS3 and hearing loss disorder: Seventeen non-GJB2 variants were found in 10 genes (TECTA, NOG, SLC26A4, PCDH15, TMPRSS3, USH2A, GATA3, MYO15A, SOX10, COL2A1) in 11 participants, and 5 variants (in TECTA, NOG, PCDH15, and SOX10) were novel (29.4%).<h4>Conclusion</h4>We were able to elucidate the genetic cause of hearing loss in 121 patients, with an overall diagnostic rate of 39.5%.
