Anterior Segment Dysgenesis 1, also known as anterior segment mesenchymal dysgenesis, is related to axenfeld-rieger syndrome, type 3 and anterior segment dysgenesis 5. An important gene associated with Anterior Segment Dysgenesis 1 is PITX3 (Paired Like Homeodomain 3), and among its related pathways/superpathways are Mesodermal commitment pathway and Transcriptional Regulatory Network in Embryonic Stem Cell. Affiliated tissues include eye and endothelial, and related phenotypes are posterior polar cataract and ocular anterior segment dysgenesis
