Axenfeld–Rieger syndrome is a rare autosomal dominant [2] disorder, which affects the development of the teeth, eyes, and abdominal region. [3]Axenfeld–Rieger syndrome is part of the so-called iridocorneal or anterior segment dysgenesis syndromes, [4] which were formerly known as anterior segment cleavage syndromes, anterior chamber segmentation syndromes or mesodermal dysgenesis.
Peters' (frequently misspelled as Peter's) anomaly is a specific type of mesenchymal anterior segment dysgenesis, in which there is central corneal leukoma, adhesions of the iris and cornea and abnormalities of the posterior corneal stroma, Descemet's membrane, corneal endothelium, lens and anterior chamber.
Autosomal dominant intellectual disability-craniofacial anomalies-cardiac defects syndrome is a rare genetic disorder which is characterized by multi-systemic symptoms primarily affecting the intellect and post-natal development.
Pierre Robin sequence-faciodigital anomaly syndrome, also known as Chitayat Meunier Hodgkinson syndrome, is a very rare genetic disorder which is characterized by the signs typical of Pierre Robin sequence along with facial dysmorphisms and digital anomalies. Intellect is not affected.
9q34 deletion syndrome is a rare genetic disorder. Terminal deletions of chromosome 9q 34 have been associated with childhood hypotonia , a distinctive facial appearance and developmental disability .
The varied signs and symptoms of Duane-radial ray syndrome often overlap with features of other disorders. For example, acro-renal-ocular syndrome is characterized by Duane anomaly and other eye abnormalities, radial ray malformations, and kidney defects. Both conditions can be caused by mutations in the same gene. [5]
Pierre Robin sequence [a] (/ p j ɛər r ɔː ˈ b æ̃ /; [3] abbreviated PRS) is a congenital defect observed in humans which is characterized by facial abnormalities.The three main features are micrognathia (abnormally small mandible), which causes glossoptosis (downwardly displaced or retracted tongue), which in turn causes breathing problems due to obstruction of the upper airway.
SHORT syndrome is an uncommon autosomal-dominant condition marked by ocular depression, Rieger anomaly, teething delay, small height, hyperextensibility of joints, and/or hernias. It was characterized in 1975.
