Dominant optic atrophy (DOA)
Written and reviewed by Dr Ibrahim Imam, Consultant Neurologist. Last reviewed .
Dominant optic atrophy (DOA). This is caused by mutations in the OPA1 gene. The gene encodes a dynamin-like GTPase. Fully referenced neurology checklist.
Genetics
- This is caused by mutations in the OPA1 gene
- The gene encodes a dynamin-like GTPase
- This is located on the inner mitochondrial membrane
- The transmission is autosomal dominant
