Transmission of a constitutional loss-of-function pathogenic variant from a male proband to offspring has not been reported. The term anophthalmia is often used interchangeably with severe microphthalmia because individuals with no visible eyeballs typically have some remaining eye tissue. 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). Consider referral to ophthalmo-plastic surgeon for children w/anophthalmia & extreme microphthalmia. CMA is often used as a first step. J Clin As SOX2 is a single-exon gene, there are no alternative splice transcripts and it is not subject to nonsense-mediated decay; however, loss-of-function variants have been observed throughout the exon.

"My husband and I are not carriers; our tests were completely normal. Ages 0-3 years. chromosome locus from Microphthalmia is when one or both of a baby's eyes are small. SOX2 is expressed in mouse embryonic stem cells and has been shown to act as part of a transcriptional activator complex for several important developmental genes including other genes known to be critical to eye development (e.g., PAX6 and MAF1). 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. 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.

Both the globe (human eye) and the ocular Cleveland Clinic is a non-profit academic medical center. For example, even in extreme microphthalmia, functional retinal tissue can give some light/dark perception with or without color perception. Developmental preschool is center based; for children too medically unstable to attend, home-based services are provided. Once the causative genetic alteration has been identified in an affected family member (or in a parent who has a structural chromosome rearrangement involving the 3q26.33 region), prenatal testing for a pregnancy at increased risk is possible, and preimplantation genetic testing for SOX2 disorder may be possible, depending on the specific familial genetic alteration. There are other things that may be factors in these eye conditions, including: In a newborn child, your provider can diagnose anophthalmia and microphthalmia through an examination. Edinburgh, United Kingdom, Malformations of the ears, teeth, fingers, skeleton, or genitourinary system, Mild-to-severe ID or DD in ~60% of affected males, Incl best corrected visual acuity, assessment of refractive error, fundus exam. 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 . SOX2 anophthalmia syndrome is estimated to affect 1 in 250,000 individuals. CMA designs in current clinical use target the 3q26.33 region. 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. Each of the hypothetic explanations for the embryonic origin of the small or missing eyes associated with SOX2 pathogenic variants predicts a different spectrum of clinical phenotypes. Data are compiled from the following standard references: gene from Families with limited income and resources may also qualify for supplemental security income (SSI) for their child with a disability. SOX2 anophthalmia syndrome is a rare disorder characterized by abnormal development of the eyes and other parts of the body. support organizations and/or registries for the benefit of individuals with this disorder SOX2 disorder comprises a phenotypic spectrum that can include 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 SOX2 eye defects are usually bilateral, severe, and apparent at birth or on routine prenatal ultrasound examination. Status dystonicus (a movement disorder emergency in which there is prolonged, generalized, intense, and painful muscle contraction) was originally reported in individuals with bilateral anophthalmia and a specific variant (see Genotype-Phenotype Correlations and Table 7) [Gorman et al 2016]; however, other variants, including the most common SOX2 variant, were subsequently associated with this feature in two individuals with bilateral anophthalmia or bilateral optic disc abnormality [Martinez & Madsen 2019, Pilz et al 2019]. Sox2 is involved in crystallin regulation in murine [ 22] and avian models [ 23] and humans, and SOX2 mutations cause microphthalmia and cataracts [ 24, 25 ]. in the fellow eye.
