          Abstract

          RESUMEN El síndrome de Axenfeld-Rieger es una enfermedad de origen genético de muy baja prevalencia que se hace acompañar de manifestaciones clínicas variables con afectación ocular y no ocular. Por tales razones se decidió presentar el caso de una paciente de 14 años de edad, antecedente familiar (en este caso su madre) de dicha enfermedad, con historia de retraso mental ligero, hipoacusia y mala visión en ambos ojos que se acompaña de alteraciones oculares: malformaciones a nivel del segmento anterior: deformidad de la pupila, prominencia blanquecina perilímbica que se corresponde con un embriotoxón posterior. Presenta otros signos de afectación no oculares: dismorfismo craneofacial leve, hipertelorismo, hipoplasia maxilar con aplanamiento del tercio medio facial, frente prominente, puente nasal ancho y aplastado así como anomalías dentales. Sufre complicaciones propias de la evolución de la entidad como es el glaucoma secundario, por lo que se trató con triple terapia con hipotensores oculares, en espera de la respuesta al tratamiento para, en el caso de una evolución tórpida, proceder al tratamiento quirúrgico: trabeculectomía.

          ABSTRACT Axenfeld-Rieger syndrome is a very low prevalence disease of genetic origin that is accompanied by variable clinical manifestations with ocular and non-ocular involvement. For these reasons, it was decided to present the case of a 14-years-old patient with a family history (in this case her mother) of this disease, with a history of mild mental retardation, hearing loss and poor vision in both eyes that is accompanied by ocular alterations: malformations at the level of the anterior segment: pupil deformity, perilimbic whitish prominence corresponding to a posterior embryotoxon. He presents other non-ocular signs of involvement: mild craniofacial dysmorphism, hypertelorism, maxillary hypoplasia with flattening of the midface, prominent forehead, wide and flattened nasal bridge, as well as dental anomalies. He suffers from complications inherent to the evolution of the entity, such as secondary glaucoma, for which he was treated with triple therapy with ocular hypotensive agents, pending the response to treatment, and in the case of a torpid evolution, proceed to surgical treatment: trabeculectomy.

          Axenfeld-Rieger syndrome in the age of molecular genetics.

          To review the molecular genetics of Axenfeld-Rieger syndrome and related phenotypes and to discuss how this information might affect the way that we classify these disorders. A review of historical and recent literature on Axenfeld-Rieger syndrome and related disorders. The review includes clinical and molecular genetic literature relevant to these phenotypes. Three chromosomal loci have recently been demonstrated to link to Axenfeld-Rieger syndrome and related phenotypes. These loci are on chromosomes 4q25, 6p25, and 13q14. The genes at chromosomes 4q25 and 6p25 have been identified as PITX2 and FKHL7, respectively. Mutations in these genes can cause a wide variety of phenotypes that share features with Axenfeld-Rieger syndrome. Axenfeld anomaly, Rieger anomaly, Rieger syndrome, iridogoniodysgenesis anomaly, iridogoniodysgenesis syndrome, iris hypoplasia, and familial glaucoma iridogoniodysplasia all have sufficient genotypic and phenotypic overlap that they should be considered one condition. Axenfeld-Rieger syndrome is a term that can be used to describe a variety of overlapping phenotypes. To date, at least three known genetic loci can cause these disorders. The single most important feature of these phenotypes is that they confer a 50% or greater risk of developing glaucoma. Currently there is a fairly arbitrary grouping of disorders into small categories. Considering all of these phenotypes under the heading of Axenfeld-Rieger syndrome will allow easier communication between clinicians and scientists and eliminate arbitrary and confusing subclassification.

            Axenfeld-Rieger syndrome: new perspectives.

            Axenfeld-Rieger syndrome is a genetic disease affecting multiple organ systems. In the eye, this condition manifests with varying degrees of anterior segment dysgenesis and carries a high risk of glaucoma. Other associated systemic issues include cardiovascular outflow tract malformations, craniofacial abnormalities and pituitary abnormalities, which can result in severe endocrinological sequelae. Recent advances in molecular genetics have identified two major genes, PITX2 and FOXC1, demonstrating a wide spectrum of mutations, which aids in the molecular diagnosis of the disease, although evidence exists to implicate other loci in this condition. The management of individuals affected by Axenfeld-Rieger syndrome requires a multidisciplinary approach and would include dedicated surveillance and management of glaucoma, sensorineural hearing loss, and cardiac, endocrinological, craniofacial and orthopaedic abnormalities.
