WebDec 20, 2024 · One cause of genetic hearing loss is a single-letter mutation in a gene called TMC1 that causes hair cells to produce a malformed, toxic protein, which builds up over time and eventually kills the cell. People, and mice, with this mutation suffer progressive hearing loss during youth and eventually become profoundly deaf.
