The normal‐hearing individuals in the family only had one mutant allele in the SLC26A4 gene (the father carried the SLC26A4 c.1614+5G>A mutation, and the mother and the third sister carried the SLC26A4 c.919‐2A>G mutation), confirming that the phenotype of hearing loss and EVA was co‐segregated with genotype in this family (supportive pathogenic evidence, PP1). This evidence concerns the gene SLC26A4 and hearing loss disorder.
