Abstract

Objectives: The genetics of sensorineural hearing loss is characterized by a high degree of heterogeneity. In spite of this, mutations in the SLC26A4 gene, have been reported to be the second most common contributor after those of GJB2 in many populations. However, different results have been reported for the frequency of SLC26A4 mutations in Iran, which varies between 0 and 12.3%. Here, we have taken together and reviewed the spectrum and frequency of the reported SLC26A4 mutations to provide a comprehensive collection of data for SLC26A4 mutations and HL in the Iranian population and considered founder mutations. Methods: A systematic literature review of the PubMed, Google Scholar, Web of Science, and Science Direct databases was conducted for articles published before March 2019. The primary data of these studies including the number of samples, mutation frequency and so on were extracted. Results: Nine studies involved 827 unrelated families were included and analyzed for the type and prevalence of the SLC26A4 gene mutations. Altogether 39 different genetic mutations were detected. SLC26A4 mutations were found to be 6.39% in the population studied which is significantly lower than that identified in the east Asia. However, c.1334T > G was the most common mutation accounting for 10% of the populations studied. Conclusions: This data gives an overview of the SLC26A4 mutations in Iran, which could be used for screening, diagnostic programs of live births and genetic counseling.
