Novel SOX2 mutation in autosomal dominant cataract-microcornea syndrome Penetrance appears to be complete for nonmosaic loss-of-function pathogenic variants. For those receiving IEP services, the public school district is required to provide services until age 21. 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. sox2 anophthalmia syndrome life expectancy BACKGROUND: Developmental eye anomalies, which include anophthalmia (absent eye) or microphthalmia (small eye) are an important cause of severe visual impairment in infants and young children. Community vision services through early intervention or school district, Recurrent variant specifically assoc w/status dystonicus [. The incidence of parental germline mosaicism in, The family history of some individuals diagnosed with, If a parent is affected and/or has the genetic alteration identified in the proband, the risk to the sibs of inheriting the genetic alteration is 50%. 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]. It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene. Family history is consistent with autosomal dominant inheritance, including simplex cases (i.e., a single occurrence in a family). In 1960, on average, persons with Down syndrome lived to be about 10 years old. For a review article see Julian et al [2017]. SOX2 is a single exon transcription factor previously associated with anophthalmia [ 18, 19 ], microphthalmia [ 20 ], and coloboma [ 21 ]. . See Quick Reference for an explanation of nomenclature. These conditions may also occur with other eye conditions or medical problems elsewhere on the body. The risk to the sibs of the proband depends on the genetic status of the proband's parents: Other family members. See our, URL of this page: https://medlineplus.gov/genetics/condition/sox2-anophthalmia-syndrome/. 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. The incidence of parental germline mosaicism in. Congenital anophthalmia is a developmental disorder in which the eye does not develop or is underdeveloped. GeneReviews chapters are owned by the University of Washington. 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. This is an autosomal dominant disorder secondary to heterozygous mutations in the SOX2 gene (3q26.33). make informed medical and personal decisions. For example, even in extreme microphthalmia, functional retinal tissue can give some light/dark perception with or without color perception.

GARD: 19 Anophthalmia plus syndrome (APS) is a very rare syndrome that involves malformations in multiple organs of the body. Note: Testing of parental DNA may not detect all instances of somatic and germline mosaicism. Depending upon the severity of malformations, life expectancy can be normal but some patients have died in the neonatal period. If exome sequencing is not diagnostic, exome array (when clinically available) can detect copy number variants, such as (multi)exon deletions or duplications that may not be identified by exome sequencing.
