|My 2010 testing kit from 23andMe.|
23andMe has two tests related to hearing loss. One tests for Connexin-26-Related Sensorineural Hearing Loss (I found out I am a carrier, but it's not necessarily the cause of my deafness). The other tests for Pendred Syndrome, a hereditary condition which is characterized by deafness (I don't know about this one, although I doubt it, because I need to upgrade my account, which I plan to do soon).
Hopefully this new price will enable many more people to learn about their genetic history - or even a little bit about their ancestry.
