SOX2 | Hereditary Ocular Diseases - University Of Arizona Surgery: You might need surgery to treat cataracts, coloboma or to help with the conformer fittings. The optimal time for determination of genetic risk and discussion of the availability of prenatal/preimplantation genetic testing is before pregnancy. 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. Ted has Sox2 anophthalmia syndrome, caused by an unbalanced translocation of Chromosomes 3 and 14 and a microdeletion of Chromosome 3. 2006 May A minority of affected individuals develop early continual dystonic posturing that is similar to that seen in dystonic cerebral palsy but without evidence of basal ganglia injury on neuroimaging.

In two of these, FISH studies identified sub-microscopic deletions involving a minimum of 328 Kb and 550 Kb. Chromosomal microarray analysis (CMA) uses oligonucleotide or SNP arrays to detect genome-wide large deletions/duplications (including SOX2) that cannot be detected by sequence analysis.
