Learn About Usher Syndrome Type 2A

What is the definition of Usher Syndrome Type 2A?
Usher syndrome type 2A is a genetic condition characterized by hearing loss from birth and progressive vision loss that usually begins in adolescence or adulthood. Vision loss is due to retinitis pigmentosa. Night vision loss begins first, followed by blind spots that develop in the side (peripheral) vision. Over time, these blind spots enlarge and merge to produce tunnel vision. In some cases, vision is further impaired by clouding of the front surface of the eye (cataracts). Hearing loss ranges from mild to severe and mainly affects high tones. The degree of hearing loss varies within and among families with this condition. Unlike other forms of Usher syndrome, people with type 2A do not have difficulties with balance caused by inner ear problems. Usher syndrome type 2A is caused by genetic changes the USH2A gene and is inherited in an autosomal recessive manner.
