The phenotypic spectrum of SOX2 disorder includes anophthalmia and/or microphthalmia, brain malformations, developmental delay/ intellectual disability, esophageal atresia, hypogonadotropic hypogonadism (manifest as cryptorchidism and micropenis in males, gonadal dysgenesis infrequently in females, and delayed puberty in both sexes), pituitary hypoplasia, postnatal growth delay, hypotonia, seizures, and spastic or dystonic movements. National Library of Medicine. 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 of 3q26.33 involving SOX2.

Br J Ted has Sox2 anophthalmia syndrome, caused by an unbalanced translocation of Chromosomes 3 and 14 and a microdeletion of Chromosome 3. The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia. No phenotypes other than those discussed in this GeneReview are known to be associated with heterozygous pathogenic variants in SOX2. Abstract Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia. Symptoms include poor vision or even complete vision loss.

These early intervention services will help babies learn to walk, talk and interact with others. 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. Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia. One of these individuals, who also had a dystonic movement disorder and unilateral strabismus as the only eye defect, had a 1.6- to 2-megabase (Mb) deletion encompassing SOX2 [Dennert et al 2017].

Thalidomide treats cancer and some skin conditions. 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. Optic fissure closure defects have been reported but are not a common feature. 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. If lens induction is impaired, the predicted clinical spectrum would be congenital cataract > microphthalmia > anophthalmia. Seattle (WA): University of Washington, Seattle; 1993-2023. An ocularist is a provider who can make prosthetic devices like artificial eyes and conformers. SOX2 encodes the transcription factor SOX2 (317 amino acids) which has an HMG DNA-binding domain (amino acids 40-111), a partner-binding region, and a C-terminal transactivation region. 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).

SOX2-specific laboratory technical considerations. If the genetic alteration identified in the proband is not identified in either parent, the following possibilities should be considered: The proband inherited a pathogenic variant from a parent with germline mosaicism.

Certain defects such as those of the heart, palate and esophagus can be surgically repaired. Both cases with patient's quality of life are noted in developing country. Anophthalmia and microphthalmia are eye conditions that people are born with. The SOX2 protein regulates the activity of other genes, especially those that are important for normal development of the eyes. SOX2 anophthalmia syndrome: 12 new cases Sex Dev.

Prosthetic eyes: Prosthetic eyes are placed in empty eye sockets. 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. Schneider A, Bardakjian TM, Zhou J, Hughes N, Keep R, Dorsainville D, Kherani What are the different ways a genetic condition can be inherited? Multiple pages were reviewed for this article. SOX1 (OMIM 602148), SOX2, and SOX3 (OMIM 313430) belong to the B1 subfamily and are expressed in various phases of embryonic development and cell differentiation, in which . distributors, and/or translators comply with the GeneReviews Copyright Notice and Usage 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. Two or more of these features need to be present for a clinical diagnosis only 30% of patients have all three. 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 . It is so rare it occurs in one in 250,000 people. The absence of the eye will cause a small bony orbit, a constricted mucosal socket, short eyelids, reduced palpebral fissure Hearing device can be helpful but no treatment is available for the eyeball malformations. Surveillance: Routine follow up with specialists managing the vision, educational, endocrine, and neurologic manifestations. It can also cause seizures, brain problems, and delayed growth. It encompasses all individuals with a SOX2 pathogenic variant who should be evaluated for medically actionable manifestations across the entire phenotypic spectrum (regardless of clinical findings that prompted molecular genetic testing). For a review article see Julian et al [2017]. Esophageal atresia with or without tracheoesophageal fistula. Direct reprogramming with SOX factors: masters of cell fate. protein from UniProt. Novel mutations in PAX6, OTX2 and NDP in anophthalmia, microphthalmia and coloboma. In two of these, FISH studies identified sub-microscopic deletions involving a minimum of 328 Kb and 550 Kb.
