摘要:

目的 观察伴前庭水管扩大(EVA)的非综合征性听力障碍(NSHI)患者耳聋基因突变谱。

方法 2015年10月至2016年8月,对湖北宜昌特殊教育学校确诊为NSHI的患者85例进行颞骨CT检查,基质辅助激光解吸/电离飞行时间质谱对GJB2、GJB3、SLC26A4和线粒体DNA (mtDNA) 12S rRNA的20个耳聋相关基因突变位点进行检测。

结果 颞骨CT显示EVA患者31例。与非EVA患者相比,EVA患者携带突变的比例明显增高(χ2 = 11.160, P = 0.001),主要表现为SLC26A4基因中c.919-2A>G突变水平显著增高(χ2 = 23.870, P < 0.001)。

结论 伴EVA的NSHI患者耳聋基因突变谱不同于非EVA患者,可优化耳聋基因检测方案,为伴EVA的NSHI的早诊断、早干预提供帮助。

Abstract:

Objective To investigate the deafness genetic mutation spectrum in nonsyndromic hearing impairment (NSHI) associated with enlarged vestibular aqueducts (EVA).

Methods From October, 2015 to August, 2016, 85 patients with NSHI from Hubei Yichang Special Education School were examined with temporal bone CT, and 20 deafness-related gene mutations in GJB2, GJB3, SLC26A4and mtDNA 12S rRNA were detected with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Results A total of 31 patients were found EVA with temporal bone CT. Compared with non-EVA patients, the proportion of deafness-related gene mutations was more in patients with EVA (χ2 = 11.160, P= 0.001), especially for c.919-2A>G mutation of SLC26A4 (χ2 = 23.870, P< 0.001).

Conclusion The deafness gene mutation spectrum is different in NSHI patients with or without EVA. It is needed to optimize genetic testing scheme for deafness for early diagnosis and intervention of NSHI associated with EVA.
