Abstract
BACKGROUND Hearing loss (HL) is a prevalent sensorineural disorder, and is among the most etiologically heterogeneous disorders. With the advent of next-generation sequencing (NGS) technologies, hundreds of candidate genes can be analyzed simultaneously in a cost-effective manner. METHODS Ninety-four patients from 87 families diagnosed with non-syndromic or syndromic HL were enrolled. A custom-designed HL panel and clinical exome sequencing (CES) were applied to explore molecular etiology in the cohort, and the efficacy of the two panels was examined. RESULTS The etiologic diagnosis for HL has been identified for 36 out of 87 probands (41.4%), 28 with an autosomal recessive (AR) inheritance pattern and 8 with an autosomal dominant (AD) pattern. Candidate variants in 18 different genes were identified in the study cohort, 10 with AR inheritance pattern and 8 with AD pattern. Fourteen of the variants identified in the study were novel. CONCLUSIONS The custom-designed HL panel covers almost all known HL-associated genes, and can be used as an effective clinical diagnostic platform; CES evaluates all exons related to clinical symptoms, and is also suitable for clinical diagnosis of HL. Next-generation sequencing facilitates genetic diagnosis and improves the management of patients with HL in the clinical practice.

Abstract
ABSTRACT To understand the possible carrier status of genes associated with hereditary hearing loss (HHL) in the general population among local residents and to give genetic counseling for pregnant women.A total of 3541 subjects were recruited. We used multiplex PCR technology combined with next-generation sequencing technology to detect 100 hotspot mutations in 18 common deafness-related genes. The homozygous mutation screening results were verified using Sanger sequencing.Of the 3541 participants, 37 alleles of 8 deafness genes were detected. A total of 145 (4.09%) were found to be GJB2 gene mutation carriers, and the hotspot mutation was c.235delC (1.54%). Twenty three (0.65%) were found to be GJB3 gene mutation carriers. A total of 132 (3.37%) were found to be SLC26A4 gene mutation carriers, and the hotspot mutation was c.919-2A > G (0.49%). Forty four (1.24%) were found to be mitochondrial DNA mutation carriers. Sanger sequencing results verified that 2 cases were homozygous for the c.235delC mutation and that 1 case was homozygous for the c.754T > C mutation.Genetic testing for pregnant women and their partners allows early identification of the molecular etiology of hearing loss (HL). On the one hand, it could give genetic counseling for pregnant women, such as early diagnosis of delayed deafness and drug-susceptible deafness. On the other hand, it could be used to assess hearing conditions during pregnancy, leading to prevention and timely intervention for newborns.

Development of a community-based hearing loss prevention and control service model in Guangdong, China. BMC Public Health 2019; 19:1601. [PMID: 31783833 PMCID: PMC6884879 DOI: 10.1186/s12889-019-7910-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Accepted: 11/07/2019] [Indexed: 11/30/2022] Open
Abstract
Background Hearing loss is a prevalent sensorineural disorder and a major public health issue in China. It is suggested that half of all cases of hearing loss can be prevented through public health measures. However, national strategies for hearing healthcare are not implemented well in Guangdong and some other regions in China. Methods To develop a community-based service model for the prevention and control of hearing loss in Guangdong, we integrated the model with multiple maternal and child healthcare models, and set up a series of clinical programs along with an optimum timeline for the preventive measures and intervention treatments to take place. A total of 36,090 families were enrolled in the study, including 358 high-risk families and 35,732 general-risk families. Results The study lasted for 6.5 years, and 30,769 children were born during that period. A total of 42 children were born with congenital deafness; 17 of them were born into families with advanced genetic risks for hearing loss, 9 were born with specific medical conditions, and 16 were born into general-risk families. About one third of them were diagnosed prenatally, others were diagnosed within 3 months of age, and 72% of them received interventions initiated before 6 months of age. 13 children presented with delayed hearing loss; 9 of them were diagnosed with delayed hereditary sensorineural deafness in neonatal period, and 4 were diagnosed within 3 months after onset. Timely interventions were provided to them, with appropriate referrals and follow-ups. Beside these, 80 families were identified with genetic susceptibility to aminoglycoside ototoxicity. Detailed medication guides were provided to prevent aminoglycoside-induced hearing loss. Moreover, through health education and risk reduction strategies, the prevalence of TORCH syndrome decreased from 10.7 to 5.2 per 10,000. Additionaly, the awareness rates of health knowledge about hearing healthcare significantly increased in the cohort. Conclusions Adapting national strategies for local or district projects could be an important step in implementing hearing loss prevention measures, and developing community-based service models could be of importance in carrying them out.
