Brain MRI. 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. Gene-targeted deletion/duplication testing will detect deletions ranging from a single exon to a whole gene; however, breakpoints of large deletions and/or deletion of adjacent genes (e.g., those described by Suzuki et al [2014]) may not be detected by these methods [Chassaing et al 2014]. It is not yet clear which of these spectra are associated with SOX2 eye disorders, as most affected individuals have very small or absent eyes, which are thus morphologically unclassifiable. recurrence of SOX2 anophthalmia syndrome: phenotypically normal mother with two In females, malformations are less frequent and can include hypoplastic or hemi-uterus, ovary or vaginal agenesis, and vaginal adhesions [Errichiello et al 2018].

Talk to your provider about the medications and over-the-counter products you take to make sure that they are compatible with a healthy pregnancy. Without this Sox2 protein, the activity of genes that is important for the development of the eye is disrupted. In the US, developmental preschool through the local public school district is recommended. SOX2 is expressed in mouse embryonic stem cells and has been shown to act as part of a transcriptional activator complex for several important developmental genes including other genes known to be critical to eye development (e.g., PAX6 and MAF1). For information on selection criteria, click here. Fielder A, Ainsworth J, Moore A, Read S, Uddin J, Laws D, Pascuel-Salcedo D, . Chromosomal aberrations involving this region of chromosome 3 have also been found. a rare congenital abnormality characterized by the complete absence of ocular tissue in the orbit. To establish the extent of disease and needs in an individual diagnosed with SOX2 disorder, the evaluations summarized in Table 4 (if not performed as part of the evaluation that led to diagnosis) are recommended. Intellectual ability is highly variable, ranging from normal to profound learning disability, with the majority having moderate learning disability. Glasses or contacts. Male genital abnormalities include undescended testes (cryptorchidism) and an unusually small penis (micropenis). Spasticity, including diplegia, paraparesis, or quadriparesis was reported in 13 individuals.

Referral to an early intervention program is recommended for access to occupational, physical, speech, and feeding therapy as well as infant mental health services, special educators, and sensory impairment specialists. These conditions may also occur with other eye conditions or medical problems elsewhere on the body. There's no treatment that can create a new eye or bring vision . Children and adults who have a rare disease and their caregivers are encouraged to talk about their needs with the medical team and to reach out for the support they require. Duplications encompassing SOX2, ranging from 40 kb to 104 Mb, do not appear to cause structural eye defects, but are associated with other features of SOX2 disorder: developmental delay, intellectual disability, motor delay, hypotonia, and gastroesophageal reflux. To date, 174 individuals from 157 families have been identified with SOX2 disorder [Williamson & FitzPatrick 2014, Gorman et al 2016, Dennert et al 2017, Blackburn et al 2018].

Mesial temporal heterotopia is highly assoc w/future epilepsy. How do you know if your baby has anophthalmia or microphthalmia? Anophthalmia-esophageal atresia-genital abnormalities (AEG) syndrome was previously reported to be a distinct disorder, but is now known to be associated in some individuals with heterozygous pathogenic loss-of-function variants in SOX2 [Williamson et al 2006, Zenteno et al 2006]; thus, it appears that esophageal atresia with or without tracheoesophageal fistula is a feature of SOX2 disorder and not a separate condition. Seattle (WA): University of Washington, Seattle; 1993-2023. Individuals with SOX2 anophthalmia syndrome may also have seizures, brain abnormalities, slow growth, delayed development of motor skills (such as walking), and mild to severe learning disabilities. 1.

HGNC; Anophthalmia and microphthalmia are eye conditions that people are born with. Its a question of managing these conditions and any other conditions that might occur with them. Sox2 anophthalmia syndromeis caused by a mutation in the Sox2 gene that does not allow it to produce the Sox2 protein that regulates the activity of other genes by binding to certain regions of DNA. See Quick Reference for an explanation of nomenclature. 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. Developmental preschool is center based; for children too medically unstable to attend, home-based services are provided. Genet.
