Abstract
Se ofrece una revisión actualizada sobre el síndrome de Rett, un trastorno neurodegenerativo con un cuadro clínico característico. Ocurre solo en niñas, la mayoría de los casos son esporádicos y es genéticamente determinado. Recientemente se ha hallado en pacientes estudiando la proteína MECP2, que codifica el gen en la banda 8 de la región 2 del brazo largo del cromosomo X (Xq 28), lo cual sugiere mutación de novo de carácter dominante ligada al cromosoma X. El diagnóstico del síndrome de Rett se lleva a cabo por la observación y la valoración clínica, pues no existen marcadores bioquímicos, ni genéticos que faciliten la determinación del síndrome, y su origen se desconoce; se utilizan los criterios establecidos internacionalmente que incluyen criterios necesarios, complementarios y componentes de exclusión. El síndrome de Rett debe sospecharse en pacientes del sexo femenino, con diagnóstico de parálisis cerebral infantil o retardo mental idiopático al apoyarse en criterios establecidos internacionalmente.
An updated literature review on Rett syndrome is presented. This neurodegenerative disorder with a characteristic clinical picture only occurs in girls, most of the cases are sporadic and genetically determined. It has been recently found in patients after studying the MECP2 protein that codifies the gene in band 8 of region 2 in the long arm of X chromosome(Xq 28), which suggests a dominant X chromosome-linked dominant de novo mutation. The diagnosis of Rett syndrome is made based on observation and clinical assessment since there are no biochemical or genetic markers facilitating the determination of the syndrome and besides its origin is unknown. The internationally established criteria including necessary, complementary criteria and exclusion elements are used. Rett syndrome should be considered in female patients with infantile cerebral palsy or idiopathic mental retardation, with the support of internationally set criteria.
