There are many ways to receive support: When anophthalmia or microphthalmia is the only condition a baby has, it's called nonsyndromic or isolated. Approximately 60% of individuals diagnosed with, One individual with unilateral anophthalmia had a similarly affected mother [, Maternal transmission of an identical and recurrent pathogenic variant has been observed in two families: a four-generation family with eye defects ranging from microcornea or retinal tuft with refractive error to bilateral anophthalmia [, A mother with a pathogenic variant (heterozygous or high-level mosaicism) who was minimally affected with isolated hypogonadotropic hypogonadism had two affected children: one with bilateral anophthalmia and subtle endocrine abnormalities and the other with unilateral microphthalmia with coloboma [, Maternal somatic/germline mosaicism was reported in four families with sib recurrence of, Recommendations for the evaluation of the parents of a proband with an apparent, Molecular genetic testing (ideally of parental DNA extracted from more than one tissue source, e.g., leukocytes and buccal cells) if the proband has an intragenic. This talk should include details on what types of vaccinations you might need to be up-to-date before you get pregnant. The diagnosis of SOX2 disorder is established in a proband in whom molecular genetic testing identifies either a heterozygous intragenic SOX2 pathogenic (or likely pathogenic) variant or a deletion that is intragenic or a deletion of 3q26.33 involving SOX2 (see Table 1). Researchers dont know for sure what causes anophthalmia or what causes microphthalmia. One report from a prospective study of 50,000 newborns found an incidence of microphthalmia of 0.22 per 1,000 live births.

Genital abnormalities. Routine karyotyping with additional FISH analysis if the proband has a deletion of 3q26.33 or other chromosome rearrangement involving 3q26.33, to determine if either parent has a balanced chromosome rearrangement involving the 3q26.33 region. Schneider A, Bardakjian TM, Zhou J, Hughes N, Keep R, Dorsainville D, Kherani Two or more of these features need to be present for a clinical diagnosis only 30% of patients have all three. Chromosomal aberrations involving this region of chromosome 3 have also been found. Last reviewed by a Cleveland Clinic medical professional on 09/07/2022. The SOX2 phenotypes include a patient with anophthalmia, oesophageal abnormalities and horseshoe kidney, and a patient with a retinal dystrophy implicating SOX2 in retinal development. The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia.

As a child enters the teen years, a transition plan should be discussed and incorporated in the IEP. B r J Ophthalmol 2007; 91: 1471 . Less frequent variants, esp those that alter residues adjacent to Tyr160, are also assoc w/severe phenotype. Microphthalmia-anophthalmia-coloboma (MAC) was used as an umbrella term for the spectrum of severe eye malformations in early publications describing SOX2 eye disorders. It is so rare it occurs in one in 250,000 people. 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. affected daughters. In females, malformations are less frequent and can include hypoplastic or hemi-uterus, ovary or vaginal agenesis, and vaginal adhesions [Errichiello et al 2018]. in the pituitary, forebrain, and eye during human embryonic development.

Mutations in the SOX2 gene prevent the production of functional SOX2 protein. Developmental preschool is center based; for children too medically unstable to attend, home-based services are provided. There are other things that may be factors in these eye conditions, including: In a newborn child, your provider can diagnose anophthalmia and microphthalmia through an examination. INTRODUCTION SOX2 anophthalmia syndrome is an autosomal "Anophthalmia is the absence of one or both eyes. If CMA does not detect a copy number variant, genome sequencing and/or exome sequencing may be used. Hum Mol Genet.

These early intervention services will help babies learn to walk, talk and interact with others. Seattle (WA): University of Washington, Seattle; 1993-2023. 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. Mechanism of disease causation. Certain defects such as those of the heart, palate and esophagus can be surgically repaired. There's no treatment that can create a new eye or bring vision .

Intrafamilial clinical variability is observed in, If the genetic alteration identified in the proband cannot be detected in the leukocyte DNA of either parent, the recurrence risk to sibs is greater than that of the general population because of the possibility of parental germline mosaicism.

How are genetic conditions treated or managed? in the fellow eye. In unilateral anophthalmia, one eye is missing. 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. Abnormal development of these structures causes the signs and symptoms of SOX2 anophthalmia syndrome. Anophthalmia presents as a small, bony orbit, malar prominence, reduced palpebral fissure, short eyelids, and a constricted mucosal socket.

Your provider will be able to tell if your baby has microphthalmia or anophthalmia by looking carefully during a physical examination and doing an eye exam. Molecular genetic testing approaches can include a combination of gene-targeted testing (single-gene testing, multigene panel, and chromosomal microarray analysis [CMA]) and comprehensive Note: Testing of parental DNA may not detect all instances of somatic and germline mosaicism. 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.

The evaluation will consider cognitive abilities and sensory impairments to determine the most appropriate form of communication. This syndrome causes a decrease in the production of sox2 protein which regulates the other gene's activities which bind to other regions of DNA. It is an early marker of neurulation in chick embryos and shows site- and stage-specific expression in the developing nervous system, genital ridge, and foregut in all vertebrates studied. It is also possible that complete failure of optic vesicle formation results in anophthalmia without optic nerve formation. 1.

SOX2 anophthalmia syndrome: In addition to having no eyes or small eyes, people with this syndrome may have seizures and problems with the brain. For more information, see the GeneReviews Copyright Notice and Usage Individuals with the distinctive findings described in Suggestive Findings are likely to be diagnosed using gene-targeted testing that could include CMA (see Option 1), whereas those in whom the diagnosis of SOX2 disorder has not been considered or previously made by CMA may be diagnosed using comprehensive genomic testing (see Option 2). The Human Phenotype Ontology (HPO) enables use of precise, standardized, computationally accessible terms to describe phenotypic abnormalities.

Education of parents/caregivers regarding common seizure presentations is appropriate. 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).
