Abstract

Purpose: Uncorrected hearing loss can result in detrimental sequelae. Research addressing clinical presentation and genetic testing would inform clinical decision making.

Method: A retrospective chart review of 96 patients aged 1 month to 46 years (median age = 6 years) diagnosed with hearing loss or deafness and who underwent genetic testing at University of Rochester Medical Center from 2011 to 2021. Chi-square and Fisher's exact tests examined the relationship between a diagnostic positive genetic test result and various characteristics of hearing loss, including congenital (n = 52), noncongenital (n = 34), prelingual (n = 53), postlingual (n = 33), progressive (n = 13), not progressive (n = 47), bilateral (n = 67), unilateral (n = 26), sensorineural (n = 68), conductive (n = 14), mixed (n = 5), syndromic (n = 10), and nonsyndromic (n = 87) hearing loss. We also examined the number of patients with presence of developmental disabilities (n = 35), having a first-degree relative with hearing loss (n = 19), having hearing aids or cochlear implants (n = 45), and having a multisystem presentation prior to diagnosis (n = 45).

Results: Patients with sensorineural hearing loss (44.1%) had significantly more diagnostic positive results than those with mixed (0%) or conductive hearing loss (21.4%), p = .004. However, significantly fewer patients with disabilities (19.4%) had diagnostic positive tests than those without disabilities (43.3%), p < .05. More patients with a multisystem presentation were also found to have syndromic causes of hearing loss (23.3%) than patients who did not have a multisystem presentation, p < .05.

Conclusions: Our study suggests a significant association between sensorineural type of hearing loss and a diagnostic positive genetic test result, while the presence of disabilities was significantly associated with a nondiagnostic genetic test result. Knowledge of these findings is critical for understanding the cause of the hearing loss, identifying other associated symptoms, and determining risk to family members.

对疑似遗传性听力损失或耳聋患者基因检测结果的回顾性分析。
目的:未矫正的听力损失可能导致有害的后遗症。针对临床表现和基因检测的研究将为临床决策提供依据:方法:对 2011 年至 2021 年期间在罗切斯特大学医学中心接受基因检测的 96 名年龄在 1 个月至 46 岁(中位年龄 = 6 岁)的听力损失或耳聋诊断患者进行回顾性病历审查。利用卡方检验和费雪精确检验检验了基因检测阳性诊断结果与听力损失各种特征之间的关系,包括先天性(52 人)、非先天性(34 人)、舌前音(53 人)、舌后音(33 人)、舌后(n = 33)、进行性(n = 13)、非进行性(n = 47)、双侧(n = 67)、单侧(n = 26)、感音神经性(n = 68)、传导性(n = 14)、混合性(n = 5)、综合征(n = 10)和非综合征(n = 87)听力损失。我们还检查了存在发育障碍(n = 35)、一级亲属有听力损失(n = 19)、有助听器或人工耳蜗(n = 45)以及诊断前有多系统表现(n = 45)的患者人数:感音神经性听力损失患者(44.1%)的诊断阳性结果明显多于混合性听力损失患者(0%)或传导性听力损失患者(21.4%),P = .004。然而,检测结果呈阳性的残疾患者(19.4%)明显少于非残疾患者(43.3%),p < .05。与没有多系统表现的患者相比,更多有多系统表现的患者(23.3%)有听力损失的综合病因,P < .05:我们的研究表明,感音神经型听力损失与诊断性阳性基因检测结果之间存在显著关联,而残疾的存在与非诊断性基因检测结果之间存在显著关联。了解这些发现对于了解听力损失的原因、识别其他相关症状和确定家庭成员的风险至关重要。

期刊介绍: Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
