Anophthalmia is a birth defect where a baby is born without one or both eyes. Sensorineural hearing loss. 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. 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. in the pituitary, forebrain, and eye during human embryonic development. 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. Hearing device can be helpful but no treatment is available for the eyeball malformations. Most cases result from new mutations in the SOX2 gene and occur in people with no history of the disorder in their family. SOX2 plays a critical role An ophthalmologist is a medical doctor who is trained in diagnosing and treating eye conditions and vision conditions. Education of parents/caregivers regarding common seizure presentations is appropriate. 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. It is not yet clear which of these spectra are associated with SOX2 eye disorders, as most affected individuals have very small or absent eyes, which are thus morphologically unclassifiable. Microphthalmia, anophthalmia and coloboma (MAC) are a group of birth eye conditions that affect 3 to 30 per 100,000 newborns. Pilz RA, Korenke GC, Steeb R, Strom TM, Felbor U, Rath M. Exome sequencing identifies a recurrent SOX2 deletion in a patient with gait ataxia and dystonia lacking major ocular malformations. Before placement, an evaluation is made to determine needed services and therapies and an individualized education plan (IEP) is developed for those who qualify based on established motor, language, social, or cognitive delay. as in some patients with SOX2 . In females, malformations are less frequent and can include hypoplastic or hemi-uterus, ovary or vaginal agenesis, and vaginal adhesions [Errichiello et al 2018]. For issues to consider in interpretation of sequence analysis results, click here. 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. Family history is consistent with autosomal dominant inheritance, including simplex cases (i.e., a single occurrence in a family). SOX2 disorder, caused by an intragenic SOX2 pathogenic variant or a deletion of 3q26.33 involving SOX2, is an autosomal dominant disorder. 23. 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].

Note: The severity of disease and specific clinical findings vary and cannot be accurately predicted by the family history or results of molecular genetic testing. Abstract Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia. 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 . 1. 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. In the 174 individuals reported (114 individuals reviewed by Williamson & FitzPatrick [2014] plus 60 individuals reported subsequently), 76 (44%) had bilateral anophthalmia, 23 (13%) had anophthalmia with contralateral microphthalmia, and 20 (12%) had bilateral microphthalmia. Anophthalmia-esophageal atresia-genital abnormalities (AEG) syndrome was previously reported to be a distinct disorder, but is now known to be associated in some individuals with heterozygous pathogenic loss-of-function variants in SOX2 [Williamson et al 2006, Zenteno et al 2006]; thus, it appears that esophageal atresia with or without tracheoesophageal fistula is a feature of SOX2 disorder and not a separate condition. recurrence of SOX2 anophthalmia syndrome: phenotypically normal mother with two 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. 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. You must talk to your provider if you take isotretinoin and thalidomide. National Library of Medicine. 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. For a review article see Julian et al [2017]. 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). Spasticity, including diplegia, paraparesis, or quadriparesis was reported in 13 individuals. Hearing aids may be helpful per audiologist/otolaryngologist. The absence of the eye will cause a small bony orbit, a constricted mucosal socket, short eyelids, reduced palpebral fissure Deml B, Reis LM, Lemyre E, Clark RD, Kariminejad A, Semina EV. Am J Med Genet A. 2008;2(4-5):194-9. doi: 10.1159/000152035. In a small number of cases, people with SOX2 anophthalmia syndrome have inherited the altered gene from an unaffected parent who has a SOX2 mutation only in their sperm or egg cells. An oculoplastic surgeon is a surgeon who has special training with the eyes, the eye sockets and the bones that make them up. Ophthalmo-acromelic syndrome is a condition that results in malformations of the eyes, hands, and feet. Isotretinoin treats acne. Julian LM, McDonald AC, Stanford WL. Direct reprogramming with SOX factors: masters of cell fate. The ' SOX2 anophthalmia syndrome' encompasses sclerocornea, cataracts, persistent hyperplastic primary vitreous and optic disc dysplasia as well as non-ocular features like mental retardation, neurological abnormalities, facial dysmorphisms, post-natal growth failure, oesophageal pathology and anomalies of male genitalia [ 14, 15 ]. 1;15(9):1413-22. doi: 10.1093/hmg/ddl064. Both the globe (human eye) and the ocular If lens induction is impaired, the predicted clinical spectrum would be congenital cataract > microphthalmia > anophthalmia. SOX2 eye defects are usually bilateral, severe, and apparent at birth or on routine prenatal ultrasound examination. See Genetic Counseling for issues related to testing of at-risk relatives for genetic counseling purposes. The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia. Consider referral to ophthalmo-plastic surgeon for children w/anophthalmia & extreme microphthalmia. Without this Sox2 protein, the activity of genes that is important for the development of the eye is disrupted. Status dystonicus in two patients with SOX2-anophthalmia syndrome and nonsense mutations. http://www.ncbi.nlm.nih.gov/books/NBK1300/. 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. club elite rhythmic .
