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. 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 of 3q26.33 involving SOX2. . It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene. The term anophthalmia is often used . Approximately 2/3 of all cases of anophthalmia are determined to be of genetic basis. 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].
