The SOX2 anophthalmia syndrome is emerging as a clinically recognizable disorder that has been identified in 10-15% of individuals with bilateral anophthalmia. The ability to determine the size of the deletion/duplication depends on the type of microarray used and the density of probes in the 3q26.33 region. For clarity, excerpts The lung originates from the ventral foregut and develops into an intricate branched structure of airways, alveoli, vessels and support tissue. It is not yet clear which of these spectra are associated with SOX2 eye disorders, as most affected individuals have very small or absent eyes, which are thus morphologically unclassifiable.
