概括

在代表性不足的少数民族 (URM) 儿童中,传感神经听力损失的遗传测试显示诊断率较低. 应用特定指南改善了变种分类,减少了差异,并加强了对URM种群的护理.

科学领域:

遗传学遗传学是一个
医学诊断医学诊断医学诊断
公共卫生公共卫生

背景情况:

感官神经听力损失 (SNHL) 影响着各种人群,代表性不足的少数群体 (URM) 在遗传诊断方面面临差异.
对SNHL的遗传检测对于诊断和干预至关重要,但其有效性在不同族群之间有所不同.

研究的目的:

评估美国医学遗传学院 (ACMG) /分子病理学协会 (AMP) 针对听力损失的指导方针在改善URM儿童遗传诊断率方面的有用性.
解决SNHL的URM群体基因检测的诊断差异.

主要方法:

分析了来自715名SNHL患者的2740个变异,包括来自348名URM患者的1275个变异.
应用ACMG/AMP变体解释指南,增强听力损失特定标准,以重新分类具有不确定意义的变体 (VUS).
利用与祖先匹配的对照相对应的病例控制分析和用于变种重新分类的计算预测.

主要成果:

最初,URM队列中只有15.52%的变异被归类为可能致病的.
听力损失具体指导方针使得19个多重VUS的重新分类成为可能,父母测试有更多的潜力.
许多在祖先匹配数据库中罕见或不存在的VUS可以通过额外的数据来澄清,突出了改善诊断的潜力.

结论:

这项研究证实了将HL特定的ACMG/AMP分类应用于URM变体的有效性.
这种方法显著澄清了VUS的致病性,提高了URM患者的基因测试准确性.
提高准确性支持改善SNHL的URM儿童的临床护理和及时干预.

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
