The life expectancy of people with Down syndrome increased dramatically between 1960 and 2007. SOX2 anophthalmia syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Status dystonicus, hyperpyrexia, and acute kidney injury in a patient with SOX2-anophthalmia syndrome. hereby granted to reproduce, distribute, and translate copies of content materials for 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. Isolated hypogonadotropic hypogonadism with SOX2 mutation and anophthalmia/microphthalmia in offspring. It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene. Seizures were observed in 22 individuals. IEP services will be reviewed annually to determine whether any changes are needed. Stark Z, Storen R, Bennetts B, Savarirayan R, Jamieson RV. What is the prognosis of a genetic condition? Dystonia and spasticity. 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. Dystonia may worsen & can show acute change to status dystonicus, which should be considered a medical emergency. 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. 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). In the US, early intervention is a federally funded program available in all states that provides in-home services to target individual therapy needs.

[ Read summary ] Many factors can affect how long a person with Down syndrome lives. AAC devices can range from low-tech, such as picture exchange communication, to high-tech, such as voice-generating devices. Occasionally hypospadias is observed. SOX2 anophthalmia syndrome: 12 new cases demonstrating broader phenotype and high frequency of large gene deletions. Eligibility differs by state but is typically determined by diagnosis and/or associated cognitive/adaptive disabilities. Concerns about serious aggressive or destructive behavior can be addressed by a pediatric psychiatrist. 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. It is so rare it occurs in one in 250,000 people. [updated 2020 Jul 30]. Ayuso C, Allen L, Collin JR, Ragge NK. While both eyes are usually affected in SOX2 anophthalmia syndrome, one eye may be more affected than the other. This process is controlled by specific transcription factors, such as the SRY-related HMG-box genes SOX2 and SOX21, that are activated or repressed through . Coming to a Cleveland Clinic location?Hillcrest Cancer Center check-in changesCole Eye entrance closingVisitation, mask requirements and COVID-19 information, Notice of Intelligent Business Solutions data eventLearn more, Microphthalmia and anophthalmia are both congenital conditions that affect the eyes. 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. One report from a prospective study of 50,000 newborns found an incidence of microphthalmia of 0.22 per 1,000 live births. Both conditions are rare, and can cause vision loss or blindness. http://www.ncbi.nlm.nih.gov/books/NBK1300/. Vision and hearing consultants should be a part of the child's IEP team to support access to academic material. While most centers would consider use of prenatal testing to be a personal decision, discussion of these issues may be helpful. These major malformations constitute a surgical emergency. Surgery: You might need surgery to treat cataracts, coloboma or to help with the conformer fittings. Some people with this condition are born with a blocked esophagus (esophageal atresia), which is often accompanied by an abnormal connection between the esophagus and the trachea (tracheoesophageal fistula). 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. In: Adam MP, Everman DB, Mirzaa GM, Pagon RA, Wallace SE, SOX2 @ The Human Genetics Unit Edinburgh U.K. Gene-targeted deletion/duplication analysis, ~24% (~21% that could also be resolved by CMA & ~3% that are below the limit of detection by CMA), Bilateral microphthalmia &/or anophthalmia, Bilateral anophthalmia, optic disc aplasia/hypoplasia, Bilateral microphthalmia, coloboma, cataract, Unilateral or bilateral microphthalmia &/or anophthalmia. Penetrance appears to be complete for nonmosaic loss-of-function pathogenic variants. Both the globe (human eye) and the ocular tissue are missing from the orbit. An oculoplastic surgeon is a surgeon who has special training with the eyes, the eye sockets and the bones that make them up. SOX2 anophthalmia syndrome Luisa Sanctis 2005, American Journal of Medical Genetics Part A Microphthalmia (small eye), anophthalmia (absent eye), and coloboma (failure of optic fissure closure) (MAC) are commonly associated eye malformations with a combined birth incidence of about 2 per 10,000 . There are many ways to receive support: The degree of learning disability is not predictable by pathogenic variant type or presence or absence of eye involvement [Dennert et al 2017, Blackburn et al 2018, Errichiello et al 2018].
