Without this Sox2 protein, the activity of genes that is important for the development of the eye is disrupted. Sox2 anophthalmia syndromeis caused by a mutation in the Sox2 gene that does not allow it to produce the Sox2 protein that regulates the activity of other genes by binding to certain regions of DNA. Inheritance was observed as de novo constitutive or de novo mosaic events, or, less frequently, from parents with constitutional duplications (see DECIPHER). SOX1 (OMIM 602148), SOX2, and SOX3 (OMIM 313430) belong to the B1 subfamily and are expressed in various phases of embryonic development and cell differentiation, in which .

SOX2 disorder, caused by an intragenic SOX2 pathogenic variant or a deletion of 3q26.33 involving SOX2, is an autosomal dominant disorder. 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.

For example, even in extreme microphthalmia, functional retinal tissue can give some light/dark perception with or without color perception. Prevalence is approximately 1:250,000 (UK estimate) [Author, personal data], extrapolated from Shah et al [2011], with no population differences noted. Intrafamilial clinical variability is observed in, If the genetic alteration identified in the proband cannot be detected in the leukocyte DNA of either parent, the recurrence risk to sibs is greater than that of the general population because of the possibility of parental germline mosaicism.

For a review article see Julian et al [2017]. This may be an inappropriate acronym, as it implies that coloboma is an intrinsic part of all microphthalmia, which is not the case: coloboma has been reported but is not a common feature. Unilateral microphthalmia is the term for when the condition affects only one eye. "In simple terms these Chromosomes are snapped, swapped and a piece has gone missing," Sarah explains. Two or more of these features need to be present for a clinical diagnosis only 30% of patients have all three.
