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].

Europe PMC is an archive of life sciences journal literature. Note: Note: Per ACMG/AMP variant interpretation guidelines, the terms "pathogenic variants" and "likely pathogenic variants" are synonymous in a clinical setting, meaning that both are considered diagnostic and both can be used for clinical decision making [Richards et al 2015].

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 . Other names for microphthalmia include small eye syndrome and microphthalmos. Youll need bigger devices as your face grows. New GJA8 variants and phenotypes highlight its critical role in a broad spectrum of eye anomalies. Sox2 anophthalmia syndromeis caused by a mutation in the Sox2 gene that does not allow it to produce the Sox2 protein that regulates the activity of other genes by binding to certain regions of DNA.

This is an autosomal dominant disorder secondary to heterozygous mutations in the SOX2 gene (3q26.33). Before placement, an evaluation is made to determine needed services and therapies and an individualized education plan (IEP) is developed for those who qualify based on established motor, language, social, or cognitive delay. SOX2 anophthalmia syndrome is a rare disorder characterized by abnormal development of the eyes and other parts of the body. 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 In 2007, on average, persons with Down syndrome lived to be about 47 years old. Anophthalmia is when a baby is born without one or both of their eyes. Microphthalmia and anophthalmia may happen along with other medical conditions that occur at birth, including issues with hands and feet malformation (like polydactyly), face and mouth malformation (like cleft lip and palate) and intellectual challenges.

Gerth-Kahlert C, Williamson K, Ansari M, Rainger JK, Hingst V, Zimmermann T, Tech S, Guthoff RF, van Heyningen V, Fitzpatrick DR. Clinical and mutation analysis of 51 probands with anophthalmia and/or severe microphthalmia from a single center. This gene provides instructions for making a protein that plays a critical role in the formation . Genital abnormalities. Familial The absence of the eye will cause a small bony orbit, a constricted mucosal socket, short eyelids, reduced palpebral fissure The term anophthalmia is often used interchangeably with severe microphthalmia because individuals with no visible eyeballs typically have some remaining eye tissue. In the 174 individuals reported (114 individuals reviewed by Williamson & FitzPatrick [2014] plus 60 individuals reported subsequently), 76 (44%) had bilateral anophthalmia, 23 (13%) had anophthalmia with contralateral microphthalmia, and 20 (12%) had bilateral microphthalmia. More detailed information for clinicians ordering genomic testing can be found here. Ceroni F, Aguilera-Garcia D, Chassaing N, Bax DA, Blanco-Kelly F, Ramos P, Tarilonte M, Villaverde C, da Silva LRJ, Ballesta-Martnez MJ, Sanchez-Soler MJ, Holt RJ, Cooper-Charles L, Bruty J, Wallis Y, McMullan D, Hoffman J, Bunyan D, Stewart A, Stewart H, Lachlan K, Fryer A, McKay V, Roume J, Dureau P, Saggar A, Griffiths M, Calvas P, Ayuso C, Corton M, Ragge NK, et al. 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. Severe genital but no major ocular anomalies in a female patient with the recurrent c.70del20 variant. Male genital abnormalities include undescended testes (cryptorchidism) and an unusually small penis (micropenis). See Molecular Genetics for information on variants detected in this gene.
