These major malformations constitute a surgical emergency. Identification of significant dysregulation of the hypothalamic-pituitary-adrenal axis is particularly important to ensure that appropriate glucocorticoid supplementation is provided during periods of physiologic stress. No phenotypes other than those discussed in this GeneReview are known to be associated with heterozygous pathogenic variants in SOX2. People with SOX2 anophthalmia syndrome are usually born without eyeballs (anophthalmia), although some individuals have small eyes (microphthalmia). The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia. Occasionally hypospadias is observed.

INTRODUCTION SOX2 anophthalmia syndrome is an autosomal "Anophthalmia is the absence of one or both eyes. SOX2 disorder comprises a phenotypic spectrum that can include anophthalmia and/or microphthalmia, brain malformations, developmental delay/ intellectual disability, esophageal atresia, hypogonadotropic hypogonadism (manifest as cryptorchidism and micropenis in males, gonadal dysgenesis infrequently in females, and delayed puberty in both sexes), pituitary hypoplasia, postnatal growth delay, hypotonia, seizures, and spastic or dystonic movements. Its a specialized imaging test that may be helpful in evaluating for fetal congenital anomalies and associated complications. Some issues to consider: Consider evaluation for alternative means of communication (e.g., augmentative and alternative communication [AAC]) for individuals who have expressive language difficulties. Ted has Sox2 anophthalmia syndrome, caused by an unbalanced translocation of Chromosomes 3 and 14 and a microdeletion of Chromosome 3. SOX2 anophthalmia syndrome is estimated to affect 1 in 250,000 individuals. While most centers would consider use of prenatal testing to be a personal decision, discussion of these issues may be helpful. sox2 anophthalmia syndrome life expectancy BACKGROUND: Developmental eye anomalies, which include anophthalmia (absent eye) or microphthalmia (small eye) are an important cause of severe visual impairment in infants and young children.

Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia. In the US, developmental preschool through the local public school district is recommended. The absence of this protein disrupts the activity of genes that are essential for the development of the eyes and other parts of the body. They can also do the fitting for these devices. It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene. 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. Contact a health care provider if you have questions about your health. 2006 Feb 23 There's no treatment that can create a new eye or bring vision . As these features can be present in children without severe structural eye defects [Zenteno et al 2006, Dennert et al 2017], they are not restricted to individuals with the full AEG syndrome [Williamson et al 2006].
