Bilateral anophthalmia and brain malformations caused by a 20-bp deletion in the SOX2 gene. Recommended Evaluations Following Initial Diagnosis in Individuals with SOX2 Disorder, Treatment of Manifestations in Individuals with SOX2 Disorder. We suggest that such deletions could be a relatively common cause of SOX2 anophthalmia syndrome and both tests should be included in the initial diagnostic . This may be an inappropriate acronym, as it implies that coloboma is an intrinsic part of all microphthalmia, which is not the case: coloboma has been reported but is not a common feature. Williamson KA, Hever AM, Rainger J, Rogers RC, Magee A, Fiedler Z, Keng WT, 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~20% of affected individuals with bilateral anophthalmia/severe microphthalmia) [Williamson & FitzPatrick 2014; Author, unpublished data] include: Initial Posting: February 23, 2006; Last Update: July 30, 2020. Occasionally hypospadias is observed.

The incidence of parental germline mosaicism in, The family history of some individuals diagnosed with, If a parent is affected and/or has the genetic alteration identified in the proband, the risk to the sibs of inheriting the genetic alteration is 50%. SOX2 disorder should be considered in individuals with the following clinical and brain MRI findings and family history. The early intervention program typically assists with this transition. An ocularist is a provider who can make prosthetic devices like artificial eyes and conformers. SOX2 - Oxford Academic SOX2 anophthalmia syndrome: 12 new cases demonstrating broader Mechanism of disease causation. Tracheoesophageal fistula was seen in the presence or absence of esophageal atresia. As the lung develops, cells become specified and differentiate into the various cell lineages. here. Abnormal development of these structures causes the signs and symptoms of SOX2 anophthalmia syndrome. SOX2 anophthalmia syndrome Clinical Information Anophthalmos-. In: Adam MP, Everman DB, Mirzaa GM, Pagon RA, Wallace SE, Approximately 60% of affected individuals have a de novo genetic alteration. Here we provide a detailed description of the clinical features associated with SOX2 mutations in the five individuals with reported mutations and four newly identified cases (including the first reported SOX2 missense mutation). 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]. According to some estimates, these conditions (anophthalmia and microphthalmia) affect about 1 in 5,200 to 1 in 10,000 infants born each year in the U.S. This is consistent with the known expression of SOX2 in the endoderm and genital ridge during development of chick and mouse embryos. Schneider A, Young TL. 2007 Nov;91(11):1471-6. doi: 10.1136/bjo.2007.117929. Intellectual ability is highly variable, ranging from normal to profound learning disability, with the majority having moderate learning disability. Bakrania P, Robinson DO, Bunyan DJ, et al. Novel SOX2 partner-factor domain mutation in a four-generation family. Note: Testing of parental DNA may not detect all instances of somatic and germline mosaicism. What are the different ways a genetic condition can be inherited? They often arise in conjunction with other ocular defects such as coloboma and orbital cyst. use. Two Cases of Anophthalmia and Quality Of Life - ResearchGate Molecular genetic testing approaches can include a combination of gene-targeted testing (single-gene testing, multigene panel, and chromosomal microarray analysis [CMA]) and comprehensive As SOX2 is a single-exon gene, there are no alternative splice transcripts and it is not subject to nonsense-mediated decay; however, loss-of-function variants have been observed throughout the exon. Selection and monitoring methods for xenotransplantation - US11424007B2 The term anophthalmia is often used . 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). Tziaferi V, Kelberman D, Dattani MT. In females, malformations are less frequent and can include hypoplastic or hemi-uterus, ovary or vaginal agenesis, and vaginal adhesions [Errichiello et al 2018]. ABA therapy is targeted to the individual child's behavioral, social, and adaptive strengths and weaknesses and typically performed one on one with a board-certified behavior analyst. Variants may include small intragenic deletions/insertions and missense, nonsense, and splice site variants; typically, whole-exon or whole-gene deletions/duplications are not detected. 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. 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: Adam MP, Everman DB, Mirzaa GM, et al., editors. University of Washington, Seattle, Seattle (WA). Almost all SOX2 pathogenic variants reported to date appear to represent heterozygous loss of function; thus, it is difficult to draw genotype-phenotype correlations. The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia. How can gene variants affect health and development? The remaining individuals have a wide spectrum of eye malformations including the following: Thirteen individuals with loss-of-function SOX2 variants had bilateral structurally normal eyes. For a review article see Julian et al [2017]. Fantes J, Ragge NK, Lynch SA, McGill NI, Collin JR, Howard-Peebles PN, Hayward C, Vivian AJ, Williamson K, van Heyningen V, FitzPatrick DR. Mutations in SOX2 cause anophthalmia. sox2 anophthalmia syndrome life expectancy The evaluation will consider cognitive abilities and sensory impairments to determine the most appropriate form of communication. Microphthalmia and anophthalmia may happen along with other medical conditions that occur at birth, including issues with hands and feet malformation (like polydactyly), face and mouth malformation (like cleft lip and palate) and intellectual challenges. BMP4 loss-of-function mutations in developmental eye disorders including SHORT syndrome. Make sure you get prenatal care (care before birth) early and consistently. Williamson KA, Hall HN, Owen LJ, Livesey BJ, Hanson IM, Adams GGW, Bodek S, Calvas P, Castle B, Clarke M, Deng AT, Edery P, Fisher R, Gillessen-Kaesbach G, Heon E, Hurst J, Josifova D, Lorenz B, McKee S, Meire F, Moore AT, Parker M, Reiff CM, Self J, Tobias ES, Verheij JBGM, Willems M, Williams D, van Heyningen V, Marsh JA, FitzPatrick DR. Recurrent heterozygous PAX6 missense variants cause severe bilateral microphthalmia via predictable effects on DNA-protein interaction. Some affected individuals have inherited the genetic alteration from either an affected mother (transmission from an affected father to child has not been reported to date) or an unaffected parent with germline mosaicism. Developmental Disabilities Administration (DDA) enrollment is recommended. There are many ways to receive support: Surgery: You might need surgery to treat cataracts, coloboma or to help with the conformer fittings. Reference to "pathogenic variants" in this section is understood to include any likely pathogenic variants. 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. Severe genital but no major ocular anomalies in a female patient with the recurrent c.70del20 variant. 2006 Feb 23 Variable expressivity is observed with some recurrent pathogenic variants (Table 7). SOX2 anophthalmia syndrome. However, its also possible to diagnose these conditions during pregnancy. 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. 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]. Verma AS, Fitzpatrick DR. Anophthalmia and microphthalmia. Gorman KM, Lynch SA, Schneider A, Grange DK, Williamson KA, FitzPatrick DR, King MD. SOX2 anophthalmia syndrome - PubMed Isolated hypogonadotropic hypogonadism with SOX2 mutation and anophthalmia/microphthalmia in offspring. For details about heterozygous deletions of 3q26.33 involving SOX2, see Molecular Genetics. See Genetic Counseling. Genital abnormalities. Treatment Depending upon the severity of malformations, life expectancy can be normal but some patients have died in the neonatal period. [3] Microphthalmia-associated transcription factor (MITF), located on chromosome 14q32, is associated with one form of isolated microphthalmia (MCOP1). SOX2 anophthalmia syndrome is estimated to affect 1 in 250,000 individuals. Schneider A, Bardakjian TM, Zhou J, Hughes N, Keep R, Dorsainville D, Kherani Thalidomide treats cancer and some skin conditions. 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. If lens induction is impaired, the predicted clinical spectrum would be congenital cataract > microphthalmia > anophthalmia. W/attention to brain/pituitary malformations, optic nerve/chiasm/tract. In two of these, FISH studies identified sub-microscopic deletions involving a minimum of 328 Kb and 550 Kb. 2008 Nov 1;146A(21):2794-8. doi: Microphthalmia means that one eye or both eyes dont develop fully so they are small and disorganized.

For more information, see the GeneReviews Copyright Notice and Usage Youll need bigger devices as your face grows. Abstract Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia. MedlinePlus also links to health information from non-government Web sites. SOX2 anophthalmia syndrome is a rare disorder characterized by abnormal development of the eyes and other parts of the body. and their families. The term "SOX2 disorder" is used in this GeneReview to refer to the complete phenotypic spectrum associated with heterozygous SOX2 pathogenic variants.
