Standards and guidelines for the interpretation of sequence variants: a joint consensus recommendation of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology. Last reviewed by a Cleveland Clinic medical professional on 09/07/2022. Identification of novel mutations and sequence variants in Sox2 is involved in crystallin regulation in murine [ 22] and avian models [ 23] and humans, and SOX2 mutations cause microphthalmia and cataracts [ 24, 25 ]. Its a question of managing these conditions and any other conditions that might occur with them. Brain MRI. Researchers think that the changes in genes and chromosomes may combine with environmental factors to result in conditions present at birth. Glasses or contacts. Consultation with a developmental pediatrician is recommended to ensure the involvement of appropriate community, state, and educational agencies (US) and to support parents in maximizing quality of life. However, its also possible to diagnose these conditions during pregnancy. Information on exact seizure type is limited, but most appeared to be grand mal tonic-clonic seizures that appeared in early childhood and responded well to standard anticonvulsant medication. How can gene variants affect health and development? This is consistent with the known expression of SOX2 in the endoderm and genital ridge during development of chick and mouse embryos.
