Lenz microphthalmia syndrome: In addition to small eyes, people with this syndrome may have uncontrolled eye movements, learning issues and problems with the skeletal and urinary systems. About 10 percent to 15 percent of people with anophthalmia in both eyes have SOX2 syndrome. SOX2 syndrome is estimated to affect 1 in 250,000 individuals. This condition is caused by an extra X chromosome in each of a female's cells. Mutations in the SOX2 gene cause SOX2 syndrome and is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is . Special education law requires that children participating in an IEP be in the least restrictive environment feasible at school and included in general education as much as possible, when and where appropriate.
