An Unexpected Cause of Ptosis: 22q11.2 Duplication Syndrome

We describe a patient of 22q11.2 duplication syndrome presenting with bilateral ptosis who has normal psychomotor development. Cranial magnetic resonance imaging and electromyography with repetitive nerve stimulation were normal. Chromosome microarray analysis was performed, and the patient was found to have a de novo 2.8 Mb duplication at 22q11.21. To our knowledge, bilateral ptosis and normal psychomotor development with 22q11.2 duplication syndrome has not been described. The 22q11.2 duplication syndrome should be considered in the differential diagnosis of ptosis. This case report contributes to an expanding clinical spectrum of patients with 22q11.2 duplication syndrome.
