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). Sex Dev. Expansion of the Human Phenotype Ontology (HPO) knowledge base and resources. If you have it, your cornea doesnt reach 10 mm in diameter even when youre an adult. Abnormal development of these structures causes the signs and symptoms of SOX2 anophthalmia syndrome. Am J Med Genet A. Reference to "pathogenic variants" in this section is understood to include any likely pathogenic variants. . Identification of novel mutations and sequence variants in the SOX2 and CHX10 genes in patients with anophthalmia/microphthalmia. 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. About 10 percent to 15 percent of people with anophthalmia in both eyes have SOX2 syndrome. While most centers would consider use of prenatal testing to be a personal decision, discussion of these issues may be helpful.
