Overview

Lenz microphthalmia syndrome is a genetic disorder that causes abnormal development of the eyes and several other parts of the body.  Eye symptoms vary, but may include underdeveloped (small) or absent eyes, cataract, nystagmus, coloboma (a gap or split in structures that make up the eye), and glaucoma. Eye symptoms may affect one or both eyes and may cause vision loss or blindness.  Other signs and symptoms may include abnormalities of the ears, teeth, hands, skeleton, urinary system and occasionally heart defects.[1]  Around 60% of people with this condition have delayed development or intellectual disability ranging from mild to severe.[2] Mutations in the BCOR gene cause some cases of Lenz microphthalmia syndrome. The other causative gene(s) have yet to be identified. This condition is inherited in an X-linked recessive fashion.[1][2]
