Prevalence is approximately 1:250,000 (UK estimate) [Author, personal data], extrapolated from Shah et al [2011], with no population differences noted. SOX2 disorder, caused by an intragenic SOX2 pathogenic variant or a deletion of 3q26.33 involving SOX2, is an autosomal dominant disorder. 1. Introduction. In males, micropenis and cryptorchidism (often a manifestation of congenital hypogonadotropic hypogonadism) are common. When the phenotypic findings suggest the diagnosis of SOX2 disorder, molecular genetic testing approaches can include single-gene testing or use of a multigene panel: Comprehensive (PDF) Case Report: Anophthalmia | Duong Dieu - Academia.edu 2006 May Approximately 2/3 of all cases of anophthalmia are determined to be of genetic basis.

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. Bilateral microphthalmia is the term for when the condition affects both eyes. Concerns about serious aggressive or destructive behavior can be addressed by a pediatric psychiatrist. American Academy of Ophthalmology. This is an autosomal dominant disorder secondary to heterozygous mutations in the SOX2 gene (3q26.33).

The SOX2 phenotypes include a patient with anophthalmia, oesophageal abnormalities and horseshoe kidney, and a patient with a retinal dystrophy implicating SOX2 in retinal development. While most centers would consider use of prenatal testing to be a personal decision, discussion of these issues may be helpful. Pavone P, Cho SY, Pratic AD, Falsaperla R, Ruggieri M, Jin DK. Depending upon the severity of malformations, life expectancy can be normal but some patients have died in the neonatal period. The following information represents typical management recommendations for individuals with developmental delay/ intellectual disability in the United States; standard recommendations may vary from country to country.

The life expectancy of people with Down syndrome increased dramatically between 1960 and 2007. Mutations in the SOX2 gene cause SOX2 syndrome and is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is .

Anophthalmia means that one or both eyes dont develop at all so they are missing. It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene.

People can be born with one or two small eyes (microphthalmia) or without one or both eyes (anophthalmia). SOX2 anophthalmia syndrome: 12 new cases What are the different ways a genetic condition can be inherited? Mutations in the SOX2 gene cause SOX2 anophthalmia syndrome. The majority of affected individuals have some evidence of hypothalamic-pituitary axis dysfunction when detailed measurement of growth hormone and gonadotropins is undertaken [Tziaferi et al 2008]. GeneReviews staff have not independently verified the classification of variants. 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). Guichet A, Triau S, Lepinard C, Esculapavit C, Biquard F, Descamps P, Encha-Razavi F, Bonneau D. Prenatal diagnosis of primary anophthalmia with a 3q27 interstitial deletion involving SOX2.

Seizures were observed in 22 individuals. Embryology, Eye Malformations Article - StatPearls In addition to a pediatrician or internist, someone with either of these conditions will probably need an ophthalmologist, an ocularist and an oculoplastic surgeon. The eyes are often absent or severely underdeveloped (anophthalmia), or they may be abnormally small (microphthalmia). ~50% of affected individuals had DD or autism. support organizations and/or registries for the benefit of individuals with this disorder The role of SOX2 in hypogonadotropic 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.

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. SOX2 anophthalmia syndrome is a rare disorder characterized by abnormal development of the eyes and other parts of the body. The lung originates from the ventral foregut and develops into an intricate branched structure of airways, alveoli, vessels and support tissue.
