And we also found, within the sensory cells, we found number of specific outer hair cells are decreased, but the inner hair cells are intact."
Hereditary deafness is relatively rare. Much more common is hearing loss that comes with age or exposure to noise. Right now, about the only treatment is hearing aids. But David Ornitz says a better understanding of how the FGF20 gene is linked to the body's system for capturing sound could lead to new therapies. "Eventually, it might be possible to use a gene-therapy approach or some other drug-type approach, in which you could actually correct a deficit due to loss or inactivation of FGF20. But that will require quite a bit more research." David Ornitz, Sung-Ho Huh and their colleagues published their research in the journal PLoS Biology.韩国出生的博士后研究员宋浩许解释说：“因此，我们发现有分散形成的感觉细胞，而且我们还发现，在感觉细胞内部，我们发现特定的外毛细胞的数量有所减少。但，内毛细胞都完好无损。
遗传性耳聋是比较少见的。更常见的是，随着年龄的增长或长期处于嘈杂环境中所导致的听力丧失。眼下，唯一的治疗方法是佩戴助听器。但大卫奥尼茨说，若能更好地了解FGF20基因是如何与人体的系统配合从而捕捉声音，新的治疗方法可能会因此诞生。“最终，使用基因治疗方法或其他一些药物治疗方法来修复由于FGF20基因丧失或失活导致的缺陷可能会成为现实。但是，那将需要相当多的研究。”大卫奥尼茨、宋浩许和他们的同事在PLoS Biology杂志发表了他们的研究。
