In addition, three deafness-related gene GJB3 (gap junction protein beta 3), MT-RNR1 (mitochondrially encoded 12S rRNA), and MTTL1 (mitochondrially encoded tRNA leucine 1) variants, excluded in the positive reports due to controversial genotype–phenotype correlation, also had higher prevalences of 0.34% (72 in 21,442), 0.23% (49 in 21,442) and 0.10% (22 in 21,442), respectively. This evidence concerns the gene MT-RNR1 and deafness.
