Abnormal development of these structures causes the signs and symptoms of SOX2 anophthalmia syndrome. ABA therapy is targeted to the individual child's behavioral, social, and adaptive strengths and weaknesses and typically performed one on one with a board-certified behavior analyst. 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). Septum pellucidum defects, cerebellar hypoplasia, hypothalamic hamartoma, arachnoid cyst, and sellar or suprasellar tumors are also reported in multiple individuals [Ragge et al 2005, Sisodiya et al 2006, Gerth-Kahlert et al 2013, Blackburn et al 2018].

Schneider A, Bardakjian TM, Zhou J, Hughes N, Keep R, Dorsainville D, Kherani INTRODUCTION SOX2 anophthalmia syndrome is an autosomal "Anophthalmia is the absence of one or both eyes. Here we provide a detailed description of the clinical features associated with SOX2 mutations in the five individuals with reported mutations and four newly identified cases (including the first reported SOX2 missense mutation). PDF Two Cases of Anophthalmia and Quality of Life 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. How can gene variants affect health and development? OMIM; The estimated risk depends on the specific chromosome rearrangement. If lens induction is impaired, the predicted clinical spectrum would be congenital cataract > microphthalmia > anophthalmia. Variants may include small intragenic deletions/insertions and missense, nonsense, and splice site variants; typically, whole-exon or whole-gene deletions/duplications are not detected. See Table A. [updated 2020 Jul 30].
