This study aimed to investigate the carrier frequencies of common deafness genes in the Chinese population who underwent carrier screening and to follow up on pregnancy outcomes in high-chance couples.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Individual females or couples in preconception or early pregnancy were recruited from two hospitals in China. Carrier screening for common deafness genes in the Chinese population, including the <jats:italic>GJB2<\/jats:italic> and <jats:italic>SLC26A4<\/jats:italic> genes, was performed using next-generation sequencing technology. Genetic counseling was provided to subjects before and after testing.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Of the 9,993 subjects screened, the carrier rate was 2.86% for the <jats:italic>GJB2<\/jats:italic> gene and 2.63% for the <jats:italic>SLC26A4<\/jats:italic> gene. The variant with the highest carrier frequency in <jats:italic>GJB2<\/jats:italic> was c.235delC (1.89%), and c.919\u20132A&amp;gt;G (1.08%) in <jats:italic>SLC26A4<\/jats:italic>. Of the six high-chance couples, four made alternative reproductive decisions (three with prenatal diagnosis and one with preimplantation genetic testing), with consequent termination of the birth of two affected fetuses.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> These findings confirmed the clinical utility of preconception or prenatal carrier screening for hereditary deafness.<\/jats:p>","DOI":"10.3389\/fgene.2023.1327258","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T04:16:55Z","timestamp":1704946615000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Hereditary deafness carrier screening in 9,993 Chinese individuals"],"prefix":"10.3389","volume":"14","author":[{"given":"Yanqiu","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lanlai","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaqing","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengshi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bicheng","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daqing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,1,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"347","DOI":"10.1038\/gim.2014.2","article-title":"American College of Medical Genetics and Genomics guideline for the clinical evaluation and etiologic diagnosis of hearing loss","volume":"16","author":"Alford","year":"2014","journal-title":"Genet.
