The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia. The mutation of the sox2 gene causes sox2 Anophthalmia syndrome. genomic testing (CMA, exome sequencing, exome array, genome sequencing) depending on the phenotype. . The ontology structure describes the relationship of terms to each other [Khler et al 2019]. The lung originates from the ventral foregut and develops into an intricate branched structure of airways, alveoli, vessels and support tissue. SOX2 disorder, caused by an intragenic SOX2 pathogenic variant or a deletion of 3q26.33 involving SOX2, is an autosomal dominant disorder. SOX2 is a single exon transcription factor previously associated with anophthalmia [ 18, 19 ], microphthalmia [ 20 ], and coloboma [ 21 ].

In the US, developmental preschool through the local public school district is recommended. anophthalmia has a 1 in 8 chance of having another child with anophthalmia [4]. The optimal time for determination of genetic risk and discussion of the availability of prenatal/preimplantation genetic testing is before pregnancy. 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. 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. 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]. congenital absence of the eye or eyes. MRC Institute of Genetics and Molecular Medicine Gene-targeted deletion/duplication testing will detect deletions ranging from a single exon to a whole gene; however, breakpoints of large deletions and/or deletion of adjacent genes (e.g., those described by Suzuki et al [2014]) may not be detected by these methods [Chassaing et al 2014].

Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia. Direct reprogramming with SOX factors: masters of cell fate. Triple X syndrome. Anophthalmia presents as a small, bony orbit, malar prominence, reduced palpebral fissure, short eyelids, and a constricted mucosal socket. People with SOX2 anophthalmia syndrome are usually born without eyeballs (anophthalmia), although some individuals have small eyes (microphthalmia). 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). here.

As the lung develops, cells become specified and differentiate into the various cell lineages. Disclaimer. An ophthalmologist is a medical doctor who is trained in diagnosing and treating eye conditions and vision conditions. Causes Mutations in the SOX2 gene cause SOX2 anophthalmia syndrome. Researchers think that the changes in genes and chromosomes may combine with environmental factors to result in conditions present at birth. For a review article see Julian et al [2017]. A/M is rare, but the exact incidence is unknown. 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. The eyes are often absent or severely underdeveloped (anophthalmia), or they may be abnormally small (microphthalmia). Disclaimer, Developmental Delay/ Intellectual Disability Management Issues. Most cases result from new mutations in the SOX2 gene and occur in people with no history of the disorder in their family. This is consistent with the known expression of SOX2 in the endoderm and genital ridge during development of chick and mouse embryos. How do people inherit SOX2 syndrome? hypogonadism.

Identification of novel mutations and sequence variants in 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. Your provider may suggest genetic testing before you get pregnant after discussing your medical history and your family history. sox2 anophthalmia syndrome life expectancy. 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). In two of these, FISH studies identified sub-microscopic deletions involving a minimum of 328 Kb and 550 Kb. 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. The absence of this protein disrupts the activity of genes that are essential for the development of the eyes and other parts of the body.
