If the genetic alteration identified in the proband is not identified in either parent, the following possibilities should be considered: The proband inherited a pathogenic variant from a parent with germline mosaicism. However, its also possible to diagnose these conditions during pregnancy. 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).
