Can Duane cause blindness?

DS doesn’t cause blindness and doesn’t usually lead to other health issues. In very rare cases, it has been linked to problems with bones, eyes, ears, kidneys, and the nervous system. Most of the time, only one eye is affected — usually the left one.

How does Duane syndrome affect the body?

Isolated Duane retraction syndrome is a disorder of eye movement. This condition prevents outward movement of the eye (toward the ear), and in some cases may also limit inward eye movement (toward the nose). As the eye moves inward, the eyelids partially close and the eyeball pulls back (retracts) into its socket.

In most cases, Duane syndrome is not inherited . The majority of cases of Duane syndrome occur in individuals with no history of the condition in the family.

What is the cause of Duane syndrome?

What is the cause of Duane Syndrome? Duane syndrome is due to miswiring of nerves to the eye muscles. In Duane syndrome, the 6th cranial nerve that controls the lateral rectus muscle (the muscle that rotates the eye out towards the ear) does not develop properly. Why the nerve does not develop is not fully understood.

How is Duane syndrome diagnosed?

The diagnosis of Duane syndrome is based on clinical findings. Mutations in the CHN1 gene are associated with familial isolated Duane syndrome. Direct sequencing of the CHN1 gene is available as a clinical test, and has to date detected missense mutations in seven patients and affected family members.

Are there prenatal tests for Duane syndrome?

Each child of an individual with Duane syndrome resulting from an identified pathogenic variant has a 50% chance of inheriting the variant. Prenatal and preimplantation genetic testing are possible once the causative pathogenic variant has been identified in an affected family member.
