Muscle eye brain disease (MEB) belongs to a group of genetic, degenerative muscular disorders that are present from birth (congenital muscular dystrophy). Individuals with this condition are born with muscle weakness (hypotonia), severe nearsightedness (myopia), glaucoma, and brain abnormalities. They also have developmental delay and intellectual disability, a buildup of fluid in the brain (hydrocephalus), and distinctive facial features. This condition is caused by mutations in the POMGNT1 gene and is inherited in an autosomal recessive manner. Although there is no specific treatment or cure for MEB, there are ways to manage the symptoms. A team of doctors is often needed to figure out the treatment options for each person.
