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. People can be born with one or two small eyes (microphthalmia) or without one or both eyes (anophthalmia). 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.

Without this Sox2 protein, the activity of genes that is important for the development of the eye is disrupted. Heterozygous, de novo, loss-of-function mutations in SOX2 have been shown to cause bilateral anophthalmia.
