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). 2008 Nov 1;146A(21):2794-8. doi: MRC Institute of Genetics and Molecular Medicine Molecular Genetic Testing Used in SOX2 Disorder. Anophthalmia and microphthalmia may also be part of congenital syndromes, including: You may feel concerned if youre pregnant and you find out that your child may have microphthalmia or anophthalmia. MedlinePlus links to health information from the National Institutes of Health and other federal government agencies. You may hear some people say that anophthalmia and microphthalmia are examples of eye birth defects.. They often arise in conjunction with other ocular defects such as coloboma and orbital cyst. 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]. Of the three, coloboma is the most common condition in the MAC spectrum, affecting 1 in 5000 newborns. . 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. SOX2 disorder, caused by an intragenic SOX2 pathogenic variant or a deletion of 3q26.33 involving SOX2, is an autosomal dominant disorder. Intrafamilial clinical variability is observed in, If the genetic alteration identified in the proband cannot be detected in the leukocyte DNA of either parent, the recurrence risk to sibs is greater than that of the general population because of the possibility of parental germline mosaicism. 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.

The risk to other family members depends on the genetic status of the proband's parents: if a parent has the causative genetic alteration or a balanced structural chromosome rearrangement, the parent's family members may be at risk. Intellectual ability is highly variable, ranging from normal to profound learning disability, with the majority having moderate learning disability. Beyond that, private supportive therapies based on the affected individual's needs may be considered. Chromosomal microarray analysis (CMA) uses oligonucleotide or SNP arrays to detect genome-wide large deletions/duplications (including SOX2) that cannot be detected by sequence analysis. American Academy of Ophthalmology. These conditions may also occur with other eye conditions or medical problems elsewhere on the body.

Although normal eye development is possible in SOX2 disorder, all such individuals had extraocular defects. Consider referral to ophthalmo-plastic surgeon for children w/anophthalmia & extreme microphthalmia. Duplications encompassing SOX2, ranging from 40 kb to 104 Mb, do not appear to cause structural eye defects, but are associated with other features of SOX2 disorder: developmental delay, intellectual disability, motor delay, hypotonia, and gastroesophageal reflux. Anophthalmos-. 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. Spasticity, including diplegia, paraparesis, or quadriparesis was reported in 13 individuals.
