SOX2 Disorder. De novo microdeletions and point mutations affecting SOX2 in three individuals with intellectual disability but without major eye malformations. It is so rare it occurs in one in 250,000 people. The following information represents typical management recommendations for individuals with developmental delay/ intellectual disability in the United States; standard recommendations may vary from country to country. In general, retina tissue that is present has some functional activity. Hearing aids may be helpful per audiologist/otolaryngologist. 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). "In simple terms these Chromosomes are snapped, swapped and a piece has gone missing," Sarah explains. It can also cause seizures, brain problems, and delayed growth. This is a rare disorder that can cause a child to be born without eyeballs. The SOX2 anophthalmia syndrome is emerging as a clinically recognizable disorder that has been identified in 10-15% of individuals with bilateral anophthalmia. Gene-targeted deletion/duplication analysis detects intragenic deletions or duplications. information on the nature, mode(s) of inheritance, and implications of genetic disorders to help them Heterozygous loss of function. Congenital anophthalmia is a developmental disorder in which the eye does not develop or is underdeveloped.

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). 15 A family history of anophthalmia was present in . 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. The absence of the eye will cause a small bony orbit, a constricted mucosal socket, short eyelids, reduced palpebral fissure
Medical Genetics: Mosaicism - Lucile Packard Children's Hospital 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. Certain defects such as those of the heart, palate and esophagus can be surgically repaired. Tracheoesophageal fistula was seen in the presence or absence of esophageal atresia. Ayuso C, Allen L, Collin JR, Ragge NK. Sibs of a proband. Together they are the most common cause of childhood sight impairment registration in England and Wales (18.4% of children). Congenital anophthalmia and microphthalmia are rare developmental defects of the globe. Sox2 anophthalmia syndrome is 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. The genetic architecture of microphthalmia, anophthalmia and coloboma. For a review article see Julian et al [2017]. Bakrania P, Rob inson DO, Bunyan D J et la: SOX2 anophthalmia syndrome: 12 new cases demonstrating broader phenotype and high frequency of large gene deletions. Europe PMC is an archive of life sciences journal literature. 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. Chassaing N, Gilbert-Dussardier B, Nicot F, Fermeaux V, Encha-Razavi F, Fiorenza M, Toutain A, Calvas P. Germinal mosaicism and familial recurrence of a SOX2 mutation with highly variable phenotypic expression extending from AEG syndrome to absence of ocular involvement. Mihelec M, Abraham P, Gibson K, Krowka R, Susman R, Storen R, Chen Y, Donald J, Tam PP, Grigg JR, Flaherty M, Gole GA, Jamieson RV. Anophthalmia means that one or both eyes dont develop at all so they are missing. The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia. SOX2 syndrome is estimated to affect 1 in 250,000 individuals. Anophthalmos, microphthalmos, and typical coloboma in the United Kingdom: a prospective study of incidence and risk. 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]. References GeneReviews is not responsible for the information provided by other If the primary defect is in the mechanism of optic fissure closure, the predicted order of severity would be iris coloboma, choroidal/retinal coloboma, microphthalmia with coloboma or orbital cyst, and anophthalmia. sox2 anophthalmia syndrome life expectancy. Permission is Tests that can diagnose microphthalmia and anophthalmia before birth include: Healthcare providers arent able to provide a new eye for people born with these conditions. 2006 Jun 15;15(12):2030. Taking medications that include isotretinoin (Accutane) or thalidomide during a pregnancy. Genetic Testing Registry: Anophthalmia/microphthalmia-esophageal atresia syndrome, National Organization for Rare Disorders (NORD).

Its a specialized imaging test that may be helpful in evaluating for fetal congenital anomalies and associated complications. The most common findings in affected individuals are anophthalmia (absence of one or both eyes) or severe microphthalmia (abnormally small eyes), and cleft lip and/or cleft palate.

Prostheses: Consider optically clear expanders to stimulate growth of the orbit & periorbital tissues. 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 . PT, OT, and speech services will be provided in the IEP to the extent that the need affects the child's access to academic material. With the current widespread use of advanced molecular genetic testing, it is apparent that the clinical spectrum associated with SOX2 pathogenic variants includes anophthalmia and/or microphthalmia as well as phenotypes with minimal or absent ocular findings. Reported heterozygous deletions of 3q26.33 involving SOX2 (~2%-3% of affected individuals, increasing to ~20% of affected individuals with bilateral anophthalmia/severe microphthalmia) [Williamson & FitzPatrick 2014; Author, unpublished data] include: Initial Posting: February 23, 2006; Last Update: July 30, 2020.

Molecular findings and clinical data in a cohort of 150 patients with anophthalmia/microphthalmia. Treatment of manifestations: Treatment usually involves a multidisciplinary team including as needed an experienced pediatric ophthalmologist, ophthalmo-plastic surgeon (for children with anophthalmia and/or extreme microphthalmia), and early educational intervention through community vision services and/or school district; educational support for school-age children; pediatric endocrinologist; pediatric neurologist; and physical therapist and occupational therapist. The medical team may not be aware of the multiple ways that a rare disease can change the quality of life of the patient and family. and their families. Anophthalmia presents as a small, bony orbit, malar prominence, reduced palpebral fissure, short eyelids, and a constricted mucosal socket.

Genital abnormalities have been described in affected individuals, especially males. Status dystonicus (a movement disorder emergency in which there is prolonged, generalized, intense, and painful muscle contraction) was originally reported in individuals with bilateral anophthalmia and a specific variant (see Genotype-Phenotype Correlations and Table 7) [Gorman et al 2016]; however, other variants, including the most common SOX2 variant, were subsequently associated with this feature in two individuals with bilateral anophthalmia or bilateral optic disc abnormality [Martinez & Madsen 2019, Pilz et al 2019].

Identification of novel mutations and sequence variants in un blocked games. These children should be considered at risk for status dystonicus, which can be triggered by any major physiologic stress and can lead to protracted periods of hospitalization and critical care. Expansion of the Human Phenotype Ontology (HPO) knowledge base and resources. The early intervention program typically assists with this transition. DDA is a US public agency that provides services and support to qualified individuals. The ZR13 OBD2 Code Reader by Zurich is the ultimate in code readers.
