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). use. Certain defects such as those of the heart, palate and esophagus can be surgically repaired. SOX2 is a single exon transcription factor previously associated with anophthalmia [ 18, 19 ], microphthalmia [ 20 ], and coloboma [ 21 ]. This syndrome causes a decrease in the production of sox2 protein which regulates the other gene's activities which bind to other regions of DNA.

The risk to other family members depends on the genetic status of the proband's parents: if a parent has the causative genetic alteration or a balanced structural chromosome rearrangement, the parent's family members may be at risk. 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. If a parent has a balanced structural chromosome rearrangement involving the 3q26.33 region, the risk to sibs is increased.
