I should think that genetic root causes would most "deaf"initely be helped with the drug! I’m in that category, too, with inherited sensorineural hearing loss (translation: BALD in those ear hair patches).
I’d so love to try a drug like this if it didn’t have severe side-effects. Now I’m hoping it won’t all go up in smoke like Theranos! Fingers crossed it hits the market and could be prescribed soon enough.
