The detected variants were found in nine genes (COL4A5, DIAPH1, MYO7A, MYO15A, OTOGL, TECTA, TMC1, TMPRSS3, TSPEAR) harbouring four pathogenic variants, three likely pathogenic variants and nine VUS variants associated with hearing impairment. The gene discussed is MYO7A; the disease is hearing loss disorder.
