Congenital anophthalmia and microphthalmia are rare developmental defects of the globe. Frequency refers to the number of times the term was used in all included case reports. SOX2 plays a critical role Methods used may include a range of techniques such as quantitative PCR, long-range PCR, multiplex ligation-dependent probe amplification (MLPA), and a gene-targeted microarray designed to detect single-exon deletions or duplications. De novo microdeletions and point mutations affecting SOX2 in three individuals with intellectual disability but without major eye malformations. Two or more of these features need to be present for a clinical diagnosis only 30% of patients have all three. Some people with this condition are born with a blocked esophagus (esophageal atresia), which is often accompanied by an abnormal connection between the esophagus and the trachea (tracheoesophageal fistula). Information on exact seizure type is limited, but most appeared to be grand mal tonic-clonic seizures that appeared in early childhood and responded well to standard anticonvulsant medication. Microphthalmia-anophthalmia-coloboma (MAC) was used as an umbrella term for the spectrum of severe eye malformations in early publications describing SOX2 eye disorders. Novel mutations in PAX6, OTX2 and NDP in anophthalmia, microphthalmia and coloboma. Chromosomal aberrations involving this region of chromosome 3 have also been found. Anophthalmia presents as a small, bony orbit, malar prominence, reduced palpebral fissure, short eyelids, and a constricted mucosal socket. The most common genetic cause for anophthalmia is mutated SOX2gene. The risk to other family members depends on the genetic status of the proband's parents: if a parent has the causative genetic alteration or a balanced structural chromosome rearrangement, the parent's family members may be at risk. Ages 3-5 years. CMA is often used as a first step.

SOX2 Disorder. SOX2 eye defects are usually bilateral, severe, and apparent at birth or on routine prenatal ultrasound examination. If exome sequencing is not diagnostic, exome array (when clinically available) can detect copy number variants, such as (multi)exon deletions or duplications that may not be identified by exome sequencing. Optic fissure closure defects have been reported but are not a common feature. Some of these specialists include teachers for the visually impaired, low vision therapists and low vision specialists. Note: Note: Per ACMG/AMP variant interpretation guidelines, the terms "pathogenic variants" and "likely pathogenic variants" are synonymous in a clinical setting, meaning that both are considered diagnostic and both can be used for clinical decision making [Richards et al 2015]. See Quick Reference for an explanation of nomenclature.

Once the causative genetic alteration has been identified in an affected family member (or a parent is known to have a structural chromosome rearrangement involving the 3q26.33 region), prenatal testing for a pregnancy at increased risk is possible and preimplantation genetic testing for SOX2 disorder may be possible, depending on the specific familial variant. Anophthalmia is a birth defect where a baby is born without one or both eyes. B r J Ophthalmol 2007; 91: 1471 . The SOX2 anophthalmia syndrome is emerging as a clinically recognizable disorder that has been identified in 10-15% of individuals with bilateral anophthalmia. Before placement, an evaluation is made to determine needed services and therapies and an individualized education plan (IEP) is developed for those who qualify based on established motor, language, social, or cognitive delay. Unilateral microphthalmia is the term for when the condition affects only one eye. SOX2 anophthalmia syndrome is a rare disorder characterized by abnormal development of the eyes and other parts of the body.
