What is Gyrate Atrophy of the Choroid and Retina

Gyrate atrophy of the choroid and retina is an inherited (genetic) condition that prevents the breakdown of a substance in the blood called ornithine. Ornithine is an amino acid, one of the building blocks of protein.

Ornithine aminotransferase is an enzyme that helps break down ornithine. Ornithine aminotransferase helps balance amino acids so they can correctly produce proteins.

Without enough working ornithine aminotransferase enzyme, your baby will have trouble breaking down ornithine. High amounts of ornithine can damage your baby’s eyes and other organs. Left untreated, this damage leads to the signs and symptoms of the condition.
