Autosomal Dominant Non-Syndromic Hearing Loss (DFNA): A Comprehensive Narrative Review. Biomedicines 2023; 11:1616. [PMID: 37371710 DOI: 10.3390/biomedicines11061616] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 05/26/2023] [Accepted: 05/29/2023] [Indexed: 06/29/2023] Open
Abstract
Autosomal dominant non-syndromic hearing loss (HL) typically occurs when only one dominant allele within the disease gene is sufficient to express the phenotype. Therefore, most patients diagnosed with autosomal dominant non-syndromic HL have a hearing-impaired parent, although de novo mutations should be considered in all cases of negative family history. To date, more than 50 genes and 80 loci have been identified for autosomal dominant non-syndromic HL. DFNA22 (MYO6 gene), DFNA8/12 (TECTA gene), DFNA20/26 (ACTG1 gene), DFNA6/14/38 (WFS1 gene), DFNA15 (POU4F3 gene), DFNA2A (KCNQ4 gene), and DFNA10 (EYA4 gene) are some of the most common forms of autosomal dominant non-syndromic HL. The characteristics of autosomal dominant non-syndromic HL are heterogenous. However, in most cases, HL tends to be bilateral, post-lingual in onset (childhood to early adulthood), high-frequency (sloping audiometric configuration), progressive, and variable in severity (mild to profound degree). DFNA1 (DIAPH1 gene) and DFNA6/14/38 (WFS1 gene) are the most common forms of autosomal dominant non-syndromic HL affecting low frequencies, while DFNA16 (unknown gene) is characterized by fluctuating HL. A long audiological follow-up is of paramount importance to identify hearing threshold deteriorations early and ensure prompt treatment with hearing aids or cochlear implants.

Abstract
BACKGROUND Hereditary hearing loss is a heterogeneous class of disorders that exhibits various patterns of inheritance and involves many genes. Variants in the EYA4 gene in DFNA10 are known to lead to postlingual, progressive, autosomal dominant nonsyndromic hereditary hearing loss. PATIENTS AND METHODS We collected a four-generation Chinese family with autosomal-dominant nonsyndromic hearing loss (ADNSHL). We applied targeted next-generation sequencing (TNGS) in three patients of this pedigree and whole-genome sequencing (WGS) in the proband. The intrafamilial cosegregation of the variant and the deafness phenotype were confirmed by PCR, gap-PCR and Sanger sequencing. RESULTS A novel CNV deletion at 6q23 in exons 8-11 of the EYA4 gene with a 10 bp insertion was identified by TNGS and WGS and segregated with the ADNSHL phenotypes. CONCLUSIONS Our results expanded the variant spectrum and genotype‒phenotype correlation of the EYA4 gene and autosomal dominant nonsyndromic hereditary hearing loss in Chinese Han individuals. WGS is an accurate and effective method for verifying the genomic features of CNVs.

Abstract
Autosomal dominant non-syndromic hearing loss (ADNSHL) displays gene-specific progression of hearing loss, which is amenable to sequential audioprofiling. We sought to refine the natural history of ADNSHL by examining audiometric data in 5-year increments. 2175 audiograms were included from four genetic causes of ADNSHL-KCNQ4 (DFNA2), GSDME (DFNA5), WFS1 (DFNA6/14/38), and COCH (DFNA9). Annual threshold deterioration (ATD) was calculated for each gene: for the speech-frequency pure tone average, the ATD, respectively, was 0.72 dB/year, 0.94 dB/year, 0.53 dB/year, and 1.41 dB/year, with the largest drops occurring from ages 45-50 (0.89 dB/year; KCNQ4), 5-10 (1.42 dB/year; GSDME), 40-45 (0.83 dB/year; WFS1), and 50-55 (2.09 dB/year; COCH). 5-year interval analysis of audiograms reveals the gene specific natural history of KCNQ4, GSDME, WFS1 and COCH-related progressive hearing loss. Identifying ages at which hearing loss is most rapid informs clinical care and patient expectations. Natural history data are also essential to define outcomes of clinical trials that test novel therapies designed to correct or ameliorate these genetic forms of hearing loss.

Abstract
BACKGROUND Sensorineural hearing loss is one of the most common sensory deficiencies. However, the molecular contribution to age-related hearing loss is not fully elucidated. METHODS We performed genome-wide association studies (GWAS) for hearing loss-related traits in the UK Biobank (N = 362,396) and selected a high confidence set of ten hearing-associated gene products for staining in human cochlear samples: EYA4, LMX1A, PTK2/FAK, UBE3B, MMP2, SYNJ2, GRM5, TRIOBP, LMO-7, and NOX4. RESULTS All proteins were found to be expressed in human cochlear structures. Our findings illustrate cochlear structures that mediate mechano-electric transduction of auditory stimuli, neuronal conductance, and neuronal plasticity to be involved in age-related hearing loss. CONCLUSIONS Our results suggest common genetic variation to influence structural resilience to damage as well as cochlear recovery after trauma, which protect against accumulated damage to cochlear structures and the development of hearing loss over time.

Abstract
OBJECTIVE Eyes absent 4 (EYA4) is the causative gene of autosomal dominant non-syndromic hereditary hearing loss, DFNA10. We aimed to identify a copy number variation of EYA4 in a non-syndromic sensory neural hearing loss pedigree. FAMILY AND CLINICAL EVALUATION A Japanese family showing late-onset and progressive hearing loss was evaluated. A pattern of autosomal dominant inheritance of hearing loss was recognized in the pedigree. No cardiac disease was observed in any of the individuals. METHODS Targeted exon sequencing was performed using massively parallel DNA sequencing (MPS) analysis. Scanning of the array comparative genomic hybridization (aCGH) was completed and the copy number variation (CNV) data from the aCGH analysis was confirmed by matching all CNV calls with MPS analysis. Breakpoint detection was performed by whole-genome sequencing and direct sequencing. Sequencing results were examined, and co-segregation analysis of hearing loss was completed. RESULTS We identified a novel hemizygous indel that showed CNV in the EYA4 gene from the position 133,457,057 to 133,469,892 on chromosome 6 (build GRCh38/hg38) predicted as p.(Val124_Pro323del), and that was segregated with post-lingual and progressive autosomal dominant sensorineural hearing loss by aCGH analysis. CONCLUSION Based on the theory of genotype-phenotype correlation with EYA4 mutations in terms of hearing loss and comorbid dilated cardiomyopathy, the region of amino acids 124 to 343 is hypothesized not to be the pathogenic region causing dilated cardiomyopathy. Additionally, the theory of genotype-phenotype correlation about the prevalence of dilated cardiomyopathy is thought to be rejected because of no correlation of deleted amino acid region with the prevalence of dilated cardiomyopathy. These results will help expand the research on both the coordination of cochlear transcriptional regulation and normal cardiac gene regulation via EYA4 transcripts and provide information on the genotype-phenotype correlations of DFNA10 hearing loss.

Abstract
The mutational spectrum of many genes and their contribution to the global prevalence of hereditary hearing loss is still widely unknown. In this study, we have performed the mutational screening of EYA4 gene by DHLPC and NGS in a large cohort of 531 unrelated Spanish probands and one Australian family with autosomal dominant non-syndromic hearing loss (ADNSHL). In total, 9 novel EYA4 variants have been identified, 3 in the EYA4 variable region (c.160G > T; p.Glu54*, c.781del; p.Thr261Argfs*34 and c.1078C > A; p.Pro360Thr) and 6 in the EYA-HR domain (c.1107G > T; p.Glu369Asp, c.1122G > T; p.Trp374Cys, c.1281G > A; p.Glu427Glu, c.1282-1G > A, c.1601C > G; p.S534* and an heterozygous copy number loss encompassing exons 15 to 17). The contribution of EYA4 mutations to ADNSHL in Spain is, therefore, very limited (~1.5%, 8/531). The pathophysiology of some of these novel variants has been explored. Transient expression of the c-myc-tagged EYA4 mutants in mammalian COS7 cells revealed absence of expression of the p.S534* mutant, consistent with a model of haploinsufficiency reported for all previously described EYA4 truncating mutations. However, normal expression pattern and translocation to the nucleus were observed for the p.Glu369Asp mutant in presence of SIX1. Complementary in silico analysis suggested that c.1107G > T (p.Glu369Asp), c.1281G > A (p.Glu427Glu) and c.1282-1G > A variants alter normal splicing. Minigene assays in NIH3T3 cells further confirmed that all 3 variants caused exon skipping resulting in frameshifts that lead to premature stop codons. Our study reports the first likely pathogenic synonymous variant linked to DFNA10 and provide further evidence for haploinsufficiency as the common underlying disease-causing mechanism for DFNA10-related hearing loss.

Abstract
Variants in the EYA4 gene are known to lead to autosomal dominant non-syndromic hereditary hearing loss, DFNA10. To date, 30 variants have been shown to be responsible for hearing loss in a diverse set of nationalities. To better understand the clinical characteristics and prevalence of DFNA10, we performed genetic screening for EYA4 mutations in a large cohort of Japanese hearing loss patients. We selected 1,336 autosomal dominant hearing loss patients among 7,408 unrelated Japanese hearing loss probands and performed targeted genome enrichment and massively parallel sequencing of 68 target genes for all patients. Clinical information of cases with mutations in EYA4 was gathered and analyzed from medical charts. Eleven novel EYA4 variants (three frameshift variants, three missense variants, two nonsense variants, one splicing variant, and two single-copy number losses) and two previously reported variants were found in 12 probands (0.90%) among the 1,336 autosomal dominant hearing loss families. The audiometric configuration of truncating variants tends to deteriorate for all frequencies, whereas that of non-truncating variants tends to show high-frequency hearing loss, suggesting a new correlation between genotype and phenotype in DFNA10. The rate of hearing loss progression caused by EYA4 variants was considered to be 0.63 dB/year, as found in this study and previous reports.

Varga L, Danis D, Skopkova M, Masindova I, Slobodova Z, Demesova L, Profant M, Gasperikova D. Novel EYA4 variant in Slovak family with late onset autosomal dominant hearing loss: a case report. BMC MEDICAL GENETICS 2019; 20:84. [PMID: 31101089 PMCID: PMC6525401 DOI: 10.1186/s12881-019-0806-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Accepted: 04/15/2019] [Indexed: 12/15/2022]
Abstract
Background Progressive bilateral sensorineural deafness in postlingual period may be linked to many different etiologies including genetic factors. Identification of the exact deafness cause may, therefore, be quite challenging. Here we present a family with late-onset hearing loss as an autosomal dominant trait caused by a novel EYA4 mutation. Case presentation Forty-four years old female proband clinically investigated for progressive hearing loss and occasional dizziness with positive family history for deafness was subject to molecular-genetic testing. Patient’s DNA sample was analyzed by whole exome sequencing. We identified a novel missense variant c.804G > C located at the last base pair of exon 10 in EYA4. Candidate variant was confirmed by Sanger sequencing in the proband and her family members. In silico prediction tools and co-segregation analysis were used to indicate pathogenicity of the identified variant. To confirm our hypothesis, we performed minigene assay to demonstrate if the transcript of exon 10 in EYA4 is present. We provide evidence that this mutation in vitro compromises donor site functionality and causes exon 10 skipping and frameshift that most likely results in nonsense-mediated mRNA decay. The onset of moderate to severe hearing loss in the family ranged from 10 to 40 years. The normal cardiac phenotype was confirmed by ECG and echocardiography. Conclusions We identified a novel EYA4 mutation associated with adult-onset autosomal dominant sensorineural hearing loss. This report extends the knowledge of spectrum of EYA4 mutations and demonstrates the pathogenicity of a variant affecting specific position in the gene. A comprehensive review of known EYA4 mutations is also given and their impact on cardiac phenotype is discussed. Our findings highlight the importance of genetic testing and complex clinical assessment in patients with familial progressive hearing loss.

A novel mutation of the EYA4 gene associated with post-lingual hearing loss in a proband is co-segregating with a novel PAX3 mutation in two congenitally deaf family members. Int J Pediatr Otorhinolaryngol 2018; 104:88-93. [PMID: 29287889 DOI: 10.1016/j.ijporl.2017.10.042] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2017] [Revised: 10/25/2017] [Accepted: 10/27/2017] [Indexed: 01/02/2023]
Abstract
OBJECTIVES This work was aimed at establishing the molecular etiology of hearing loss in a 9-year old girl with post-lingual non-syndromic mild sensorineural hearing loss with a complex family history of clinically heterogeneous deafness. METHODS The proband's DNA was subjected to NGS analysis of a 59-targeted gene panel, with the use of the Ion Torrent PGM platform. Conventional Sanger sequencing was used for segregation analysis in all the affected relatives. The proband and all the other hearing impaired members of the family underwent a thorough clinical and audiological evaluation. RESULTS A new likely pathogenic mutation in the EYA4 gene (c.1154C > T; p.Ser385Leu) was identified in the proband and in her 42-year-old father with post-lingual non-syndromic profound sensorineural hearing loss. The EYA4 mutation was also found in the proband's grandfather and uncle, both showing clinical features of Waardenburg syndrome type 1. A novel pathogenic splice-site mutation (c.321+1G > A) of the PAX3 gene was found to co-segregate with the EYA4 mutation in these two subjects. CONCLUSION The identified novel EYA4 mutation can be considered responsible of the hearing loss observed in the proband and her father, while a dual molecular diagnosis was reached in the relatives co-segregating the EYA4 and the PAX3 mutations. In these two subjects the DFNA10 phenotype was masked by Waardenburg syndrome. The use of NGS targeted gene-panel, in combination with an extensive clinical and audiological examination led us to identify the genetic cause of the hearing loss in members of a family in which different forms of autosomal dominant deafness segregate. These results provide precise and especially important prognostic and follow-up information for the future audiologic management in the youngest affected member.
