Axenfeld syndrome Wikipedia. Axenfeld syndrome also known as Axenfeld Rieger syndrome or Hagedoom syndrome is a rare autosomaldominant2 disorder, which affects the development of the teeth, eyes, and abdominal region. PathophysiologyeditThe molecular genetics of Axenfeld syndrome are poorly understood, but centers on three genes identified by cloning of chromosomal breakpoints from patients. This disorder is inheritable as an autosomal dominant trait,4 which means the defective gene is located on an autosome, and only one copy of the gene is sufficient to cause the disorder when inherited from a parent who has the disorder. As shown in the diagram, this gives a 5. DiagnosiseditAlthough most recognized for its correlation with the onset of glaucoma, the malformation is not limited to the eye, as Axenfeld syndrome when associated with the PITX2 genetic mutation usually presents congenital malformations of the face, teeth, and skeletal system. The most characteristic feature affecting the eye is a distinct corneal posterior arcuate ring, known as an embryotoxon. The iris is commonly adherent to the Schwalbes line posterior surface of the cornea. Diagnosis One of the three known genetic mutations which cause Rieger Syndrome can be identified through genetic samples analysis. Selective laser trabeculoplasy in the treatment of glaucoma.

About 4. 0 of Axenfeld Rieger sufferers have displayed mutations in genes PITX2,7FOXC1, and PAX6. The difference between Type 1, 2, and 3 Axenfeld Syndrome is the genetic cause, all three types display the same symptoms and abnormalities. The OMIM classification is as follows Detection of any of these mutations can give patients a clear diagnosis and prenatal procedures such as preimplantation genetic diagnosis, Chorionic villus sampling and Amniocentesis can be offered to patients and prospective parents.

Axenfeld Rieger syndrome is characterized by abnormalities of the eyes, teeth, and facial structure. Rieger Syndrome, by medical definition, is determined by the presence of malformed teeth, underdeveloped anterior segment of the eyes, and cardiac problems associated with the Axenfeld anomaly. The term Rieger syndrome is sometimes used to indicate an association with glaucoma. Glaucoma occurs in up to 5. Rieger Syndrome. Glaucoma develops during adolescence or late childhood, but often occurs in infancy. In addition, a prominent Schwalbes line, an opaque ring around the cornea known as posterior embryotoxon, may arise with hypoplasia of the iris. Below average height and stature, stunted development of the mid facial features and mental deficiencies may also be observed in patients.
