(a) Five hot-spot areas (p.H723R, c.919-2A>G, p.T410M, p.L676Q, and p.T721M) or the whole exon of SLC26A4 were sequenced in patients with bilateral enlarged vestibular aqueduct (EVA). Bi-allelic SLC26A4 mutations were detected in 111 patients. (b) Distribution of genotypes in 100 unrelated patients with bi-allelic SLC26A4 mutations.

Quantitative polymerase chain reaction (qPCR) results show that there is no difference in SLC26A4 transcript expression level between wild-type and mutant pendrin groups (p = 0.69, n = 5). Relative ratio of mRNA expression compared with wild-type was 1.07 ± 0.11, 0.97 ± 0.09 in p.H723R and p.T410M, respectively.

In silico predictions of cryptic splicing in c.919-2A>G of SLC26A4. c919-2A>G mutation results in a leaky intron 8 acceptor splice site, with Ri reduced from 12.1 to 3.9 bits. Despite the decreased Ri value, it is yet probable that normal splicing mRNA can be produced in part. Additionally, this mutation creates a new cryptic splice site at the mutant G of intron 8, with Ri value increased from −4.5 to 3.1 bits. This predicts an outcome of a single G insertion into the beginning of exon 8, which in turns leads to a premature stop codon within exon 8 due to frameshift.
