Resumen

Antecedentes.

Las repeticiones de trinucleótidos se han asociado con la esquizofrenia, pero los datos, basados en información clínica transversal, son equívocos.

Propósitos.

Examinar la relación entre el tamaño de la repetición de CAG/CTG genómico y el desarrollo premórbido en la esquizofrenia.

Método.

Se evaluó por entrevistas con los padres el desarrollo temprano y el funcionamiento premórbido de 22 pacientes con diagnóstico de esquizofrenia del DSM IV. Se utilizó la técnica de detección de la expansión de repeticiones (DER) para medir el tamaño de la repetición de CAG/CTG genómico, y la RCP para el tamaño de la repetición de CAG en los loci ERDA-1 y CTG 18.1.

Resultados.

Hubo una asociación inversa entre el tamaño de CAG/CTG y las complicaciones perinatales. Los pacientes con retraso evolutivo del habla y motor tenían repeticiones mayores. Los resultados no se debían a la expansión en los genes ERDA-1 y CTG 18.1.

Conclusiones.

La expansión de la repetición de CAG/CTG se asocia con retraso evolutivo del habla y motor en la esquizofrenia. Proponemos que el modelo evolutivo puede ser útil para la investigación en la genética de la esquizofrenia.
