The syndrome mainly affects males.

Oligophrenin-1 is a protein that in humans is encoded by the OPHN1 gene.[1][2][3]

Function

Oligophrenin 1 has 25 exons and encodes a Rho-GTPase-activating protein. The Rho protein are important mediators of intracellular signal transduction, which affects cell migration and cell morphogenesis.

Clinical significance

Mutations in this gene are responsible for non-specific X-linked intellectual disability (previously called mental retardation).[3]

OPHN1 syndrome is a rare disorder characterized by intellectual disability and changes in the part of the brain which controls movement and balance (cerebellum). The syndrome mainly affects males. It is characterized by low muscle tone (hypotonia), developmental and cognitive delay, early-onset seizures, abnormal behavior, characteristic facial features (long face, bulging forehead, under eye creases, deep set eyes, and large ears), crossed eyes (strabismus) and inability to coordinate movements.[4] [5] A small cerebellum and large ventricles can be seen on brain imaging (MRI).[4][6][7] Treatment is supportive and includes physical, occupational and speech and language therapy.[8]

OPHN1 syndrome is caused by mutations in the OPHN1 gene, which is located on the X chromosome. Inheritance is X-linked.[4] Some females who carry a mutation in the OPHN1 gene may have mild learning disabilities, mild cognitive impairment, strabismus, and subtle facial changes.[3]
