Disease at a Glance

Summary
Autosomal dominant optic atrophy plus syndrome (ADOA plus) is a rare syndrome that causes vision loss, hearing loss, and symptoms affecting the muscles. The syndrome is associated with degeneration of the optic nerve (optic atrophy). The optic nerve sends signals about what the eyes are seeing to the brain. When there is optic nerve damage, it causes vision loss. Other symptoms of ADOA plus include sensorineural hearing loss and symptoms affecting the muscles such as muscle pain and weakness. ADOA plus is caused by changes in the OPA1 gene. The syndrome is inherited in an autosomal dominant manner. A diagnosis of ADOA plus is suspected when an eye exam finds degeneration of the optic nerve (optic atrophy). The diagnosis can be confirmed with a muscle biopsy and genetic testing of the OPA1 gene.
