Rie·ger syn·drome

(rē'gĕr), [MIM*180500]
iridocorneal mesenchymal dysgenesis combined with hypodontia or anodontia and maxillary hypoplasia; autosomal dominant; there is a delayed sexual development and hypothyroidism.
See also: Rieger anomaly.

Axenfeld-Rieger syndrome

An autosomal dominant condition (OMIM:180500) characterised by hypodontia, defect of the anterior chamber of the eye, myotonic dystrophy and anal stenosis.

Molecular pathology
Type-1 Axenfield-Rieger syndrome is caused by a mutation in a homeobox transcription factor gene PITX2; a second type of A-R syndrome has a defect that maps to chomosome 14q13, RIEG2.

Rieger syndrome (RS) is a rare, autosomal dominant condition with almost complete penetrance and variable expressivity.
His facial appearance and his dark coloured eyes suggested Rieger syndrome.
Based on information revealed in taking the medical history and clinical findings, he was further referred to an ophthalmologist who reported hypoplasia of the iris stroma and an asymmetric pupil, thereby confirming the tentative diagnosis of Rieger syndrome.
His mother suspected a diagnosis of Rieger syndrome in both herself and her son.
Clinical findings were consistent with the orofacial and dental symptoms of Rieger syndrome and the boy was referred to an ophthalmologist.
The clinical relevance of the findings varies; they may only be descriptive, such as a fissured tongue in Down syndrome, but in other cases missing teeth may represent an important finding in the diagnosis of ectodermal dysplasia, X-linked recessive, incontinentia pigmenti or Rieger syndrome.
