Schneider A, Bardakjian TM, Zhou J, Hughes N, Keep R, Dorsainville D, Kherani Microphthalmia, anophthalmia and coloboma (MAC) are a group of birth eye conditions that affect 3 to 30 per 100,000 newborns. 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. . However, there are treatments that include: Theres no way to completely eliminate your risk of microphthalmia and anophthalmia, but there are ways to make pregnancy safer: Theres no cure for microphthalmia or anophthalmia. Q11.1 - Other anophthalmos - ICD List 2023 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). 15 A family history of anophthalmia was present in . Heterozygous loss of function. Malformation and/or gray matter heterotopia of the mesial temporal structures (hippocampal and parahippocampal), pituitary hypoplasia, and agenesis or dysgenesis of the corpus callosum are core features of SOX2 disorder. 2008 Nov 1;146A(21):2794-8. doi: Delayed motor development was reported in the majority of affected children; the age of achieving independent walking ranged from 12 months to four years, although some individuals never achieve independent ambulation.

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. 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. Expand All. sox2 anophthalmia syndrome life expectancy Fielder A, Ainsworth J, Moore A, Read S, Uddin J, Laws D, Pascuel-Salcedo D, It is so rare it occurs in one in 250,000 people.

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. 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. Zhou J, Kherani F, Bardakjian TM, Katowitz J, Hughes N, Schimmenti LA, In the US, developmental preschool through the local public school district is recommended. True or primary anophthalmia is incompatible with life . 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.

Identification of significant dysregulation of the hypothalamic-pituitary-adrenal axis is particularly important to ensure that appropriate glucocorticoid supplementation is provided during periods of physiologic stress. How can gene variants affect health and development? Identification of novel mutations and sequence variants in They often arise in conjunction with other ocular defects such as coloboma and orbital cyst. genomic testing, which does not require the clinician to determine which gene is likely involved, is an option when SOX2 disorder is not an easily achievable diagnosis. Stark Z, Storen R, Bennetts B, Savarirayan R, Jamieson RV. Approximately 60% of affected individuals have a de novo genetic alteration.

Gorman KM, Lynch SA, Schneider A, Grange DK, Williamson KA, FitzPatrick DR, King MD. SOX2 has been implicated in a substantial number (10-15%) of cases and in many other cases failure to develop the ocular lens often results in microphthalmia. 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. An ophthalmologist is a medical doctor who is trained in diagnosing and treating eye conditions and vision conditions.
