Story summary

Rong Grace Zhai led a study on CPD gene mutations that disrupt nitric oxide signaling in the inner ear.
The disruption damages hair cells essential for hearing.
In animal models, supplementation with L-arginine or sildenafil could restore function.
The findings suggest simple metabolic therapies may replace genetic engineering for gene-based disorders.
The study was published in the Journal of Clinical Investigation and offers hope for genetic deafness and health conditions.
