Summaries for Anterior Segment Dysgenesis 1

OMIM : 57 Anterior segment dysgeneses (ASGD or ASMD) are a heterogeneous group of developmental disorders affecting the anterior segment of the eye, including the cornea, iris, lens, trabecular meshwork, and Schlemm canal. The clinical features of ASGD include iris hypoplasia, an enlarged or reduced corneal diameter, corneal vascularization and opacity, posterior embryotoxon, corectopia, polycoria, an abnormal iridocorneal angle, ectopia lentis, and anterior synechiae between the iris and posterior corneal surface (summary by Cheong et al., 2016). Anterior segment dysgenesis is sometimes divided into subtypes including aniridia (see 106210), Axenfeld and Rieger anomalies, iridogoniodysgenesis, Peters anomaly, and posterior embryotoxon (Gould and John, 2002). Some patients with ASGD1 have been reported with the Peters anomaly subtype. In its simplist form, Peters anomaly involves a central corneal opacity, but it may also involve adherent iris strands. Some patients have keratolenticular content or cataract. The underlying defects in this form of congenital corneal opacity reside in the posterior stroma, Descemet membrane, and corneal endothelium. The disorder results from abnormal migration or function of neural crest cells and may include abnormalities of other anterior segment structures, such as the lens and iris (summary by Withers et al., 1999). (107250)

MalaCards based summary : Anterior Segment Dysgenesis 1, also known as anterior segment mesenchymal dysgenesis, is related to axenfeld-rieger syndrome, type 3 and anterior segment dysgenesis. An important gene associated with Anterior Segment Dysgenesis 1 is PITX3 (Paired Like Homeodomain 3), and among its related pathways/superpathways are C-MYB transcription factor network and Primary Focal Segmental Glomerulosclerosis FSGS. Affiliated tissues include eye and endothelial, and related phenotypes are opacification of the corneal stroma and microcornea

UniProtKB/Swiss-Prot : 75 Anterior segment dysgenesis 1: A form of anterior segment dysgenesis, a group of defects affecting anterior structures of the eye including cornea, iris, lens, trabecular meshwork, and Schlemm canal. Anterior segment dysgeneses result from abnormal migration or differentiation of the neural crest derived mesenchymal cells that give rise to components of the anterior chamber during eye development. Different anterior segment anomalies may exist alone or in combination, including iris hypoplasia, enlarged or reduced corneal diameter, corneal vascularization and opacity, posterior embryotoxon, corectopia, polycoria, abnormal iridocorneal angle, ectopia lentis, and anterior synechiae between the iris and posterior corneal surface. Clinical conditions falling within the phenotypic spectrum of anterior segment dysgeneses include aniridia, Axenfeld anomaly, Reiger anomaly/syndrome, Peters anomaly, and iridogoniodysgenesis.
