Genetic counseling is the process of providing individuals and families with Once the causative genetic alteration has been identified in an affected family member (or in a parent who has a structural chromosome rearrangement involving the 3q26.33 region), prenatal testing for a pregnancy at increased risk is possible, and preimplantation genetic testing for SOX2 disorder may be possible, depending on the specific familial genetic alteration. The majority of affected individuals have some evidence of hypothalamic-pituitary axis dysfunction when detailed measurement of growth hormone and gonadotropins is undertaken [Tziaferi et al 2008]. If exome sequencing is not diagnostic, exome array (when clinically available) can detect copy number variants, such as (multi)exon deletions or duplications that may not be identified by exome sequencing.
