Autism spectrum disorders are severe neurodevelopmental disorders with a strong genetic component. The potential role of the serotoninergic system in the development of autistic disorder has been based on the observation of hyperserotoninemia in autistic subjects and the results of drug treatment studies.

Multiple molecules involved in serotonin metabolism and neurotransmission have been studied; however, replication studies have been inconsistent. This may be partially related to the marked genetic heterogeneity of autism in desequiilbrio populations. The interactions among these genes and autism was assessed with multidimensional reduction methods. Desequi,ibrio results were consistent with previous studies conducted in other populations and provide further evidence for the implication of the serotoninergic system in the etiology of autistic disorders.

Este trastorno hace parte de los trastornos del espectro autista. En el gen SLC6A4 se identificaron variantes raras que “cosegregan” con los rasgos del espectro autista en familias con, al menos, dos casos, y estas variantes se correlacionan con la gravedad del comportamiento compulsivo Las secuencias de los Oigamiento se tomaron de la base de datos http: Las enzimas fueron escogidas empleando el software NEBcutter V2. Desequilibriio utilizaron duplicados para verificar la calidad de los genotipos y, en el caso de genotipos dudosos, se repitieron para confirmarlos.

Se verificaron inconsistencias mendelianas y se excluyeron aquellas familias que las presentaron. Todos los participantes o su representante legal, leyeron y comprendieron el documento informativo del estudio y posteriormente firmaron un consentimiento informado. Los genotipos se distribuyeron de acuerdo con lo esperado bajo el modelo del equilibrio de Hardy-Weinberg.

Los dos marcadores rs y rs se desfquilibrio en el mismo bloque de ligamiento figura 2 c. Los tres mejores modelos que explican el autismo se presentan en el cuadro 6. Este polimorfismo se transmite en forma independiente del bloque de ligamiento donde se encuentran los polimorfismos cesequilibrio y rs, como se observa en la figura 2.

Sin embargo, los hallazgos no han sido constantes, pues otros estudios han reportado el alelo L como de riesgo para autismo en poblaciones de Alemania, Israel y Portugal 10,24, Es necesario abarcar una mayor variabilidad del gen, evaluando polimorfismos en diferentes sus regiones, y posiblemente este sea un mejor factor predictor del riesgo a autismo. En elCarneiro, et al. Existen varias limitaciones en este estudio.
