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]. Polyadenylation signal variants are assoc w/familial anophthalmia. Anophthalmia presents as a small, bony orbit, malar prominence, reduced palpebral fissure, short eyelids, and a constricted mucosal socket. In females, malformations are less frequent and can include hypoplastic or hemi-uterus, ovary or vaginal agenesis, and vaginal adhesions [Errichiello et al 2018].

Anophthalmia means that one or both eyes dont develop at all so they are missing. genomic testing, which does not require the clinician to determine which gene is likely involved, is an option when SOX2 disorder is not an easily achievable diagnosis. Congenital anophthalmia is a developmental disorder in which the eye does not develop or is underdeveloped. The most common findings in affected individuals are anophthalmia (absence of one or both eyes) or severe microphthalmia (abnormally small eyes), and cleft lip and/or cleft palate. david millward security; swarovski habicht 10x40; east hanover police scanner; sample complaint car accident negligence.

SOX2 is a single exon transcription factor previously associated with anophthalmia [ 18, 19 ], microphthalmia [ 20 ], and coloboma [ 21 ]. The term anophthalmia is often used interchangeably with severe microphthalmia because individuals with no visible eyeballs typically have some remaining eye tissue. 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]. ), (https://www.marchofdimes.org/complications/anophthalmia-and-microphthalmia.aspx), (https://medlineplus.gov/genetics/condition/sox2-anophthalmia-syndrome/#references).

Referral to an early intervention program is recommended for access to occupational, physical, speech, and feeding therapy as well as infant mental health services, special educators, and sensory impairment specialists. Researchers dont know for sure what causes anophthalmia or what causes microphthalmia. An IEP provides specially designed instruction and related services to children who qualify. Approximately 60% of individuals diagnosed with, One individual with unilateral anophthalmia had a similarly affected mother [, Maternal transmission of an identical and recurrent pathogenic variant has been observed in two families: a four-generation family with eye defects ranging from microcornea or retinal tuft with refractive error to bilateral anophthalmia [, A mother with a pathogenic variant (heterozygous or high-level mosaicism) who was minimally affected with isolated hypogonadotropic hypogonadism had two affected children: one with bilateral anophthalmia and subtle endocrine abnormalities and the other with unilateral microphthalmia with coloboma [, Maternal somatic/germline mosaicism was reported in four families with sib recurrence of, Recommendations for the evaluation of the parents of a proband with an apparent, Molecular genetic testing (ideally of parental DNA extracted from more than one tissue source, e.g., leukocytes and buccal cells) if the proband has an intragenic.

Consultation with a developmental pediatrician is recommended to ensure the involvement of appropriate community, state, and educational agencies (US) and to support parents in maximizing quality of life. Methods used may include a range of techniques such as quantitative PCR, long-range PCR, multiplex ligation-dependent probe amplification (MLPA), and a gene-targeted microarray designed to detect single-exon deletions or duplications. The Human Phenotype Ontology (HPO) enables use of precise, standardized, computationally accessible terms to describe phenotypic abnormalities. Both cases with patient's quality of life are noted in developing country. The role of SOX2 in hypogonadotropic Almost all SOX2 pathogenic variants reported to date appear to represent heterozygous loss of function; thus, it is difficult to draw genotype-phenotype correlations. It is an early marker of neurulation in chick embryos and shows site- and stage-specific expression in the developing nervous system, genital ridge, and foregut in all vertebrates studied.
