CPD gene mutations tied to congenital hearing loss; lab tests point to arginine and sildenafil as potential interventions

An international team reports that rare mutations in CPD (carboxypeptidase D) cause a congenital, sensorineural form of hearing loss by disrupting arginine–nitric oxide signaling in inner‑ear hair cells. In models, arginine supplementation or sildenafil partially reversed disease‑related defects, highlighting a pathway for future therapies.
A single injection of gene therapy has significantly improved hearing in all ten patients born with a genetic form of deafness, according to a new study. Researchers delivered a working copy of the OTOF gene into the inner ear, with most patients regaining hearing within one month. The treatment, tested in China, proved safe and effective across ages from one to 24.

A large-scale study using UK Biobank data has found that adults with hearing loss who regularly use hearing aids face a significantly reduced risk of developing dementia. The research, published in The Lancet Healthy Longevity, highlights hearing loss treatment as a potential modifiable factor in dementia prevention. This comes amid growing evidence linking untreated hearing impairment to cognitive decline.
