    <abstract xml:lang="en">Introduction. The study of autistic spectrum disorders (ASD) at the genetic level is extremely important to understand their origin. In Mexico, there are few works addressed from this perspective. Objective. We investigated the role of the Brain Derived Neurotrophic Factor ( BDNF ) gene variant rs6265 G/A for single nucleotide polymorphism analysis in Mexican children with ASD using a case-control association design. Method. We made a pilot study by case-control analysis adjusting by gender, age, and ancestry. Results. Our study found no association between the BDNF rs6265 gene polymorphism and ASD [ p = .419, OR = 1.597 (.514, 4.967)]. Discussion and conclusion. Worldwide, the results of case-control association studies with the rs6265 of BDNF are controversial and do not always replicate. This may be due to the ethnicity of our population and additional factors not studied in the present work. Our study suggests that the SNP rs6265 is not contributing for ASD susceptibility in Mexican population.</abstract>

En M&eacute;xico existen pocos trabajos abordados desde esta perspectiva. Objetivo. Investigamos el papel de la variante del gen rs6265 G/A del factor neurotr&oacute;fico derivado del cerebro ( BDNF ) para el an&aacute;lisis del polimorfismo de un solo nucle&oacute;tido en ni&ntilde;os mexicanos con TEA por medio de un dise&ntilde;o de asociaci&oacute;n de casos y controles. M&eacute;todo. Realizamos un estudio piloto mediante un an&aacute;lisis de casos y controles ajustando por g&eacute;nero, edad y ancestr&iacute;a. Resultados. Nuestro estudio no encontr&oacute; asociaci&oacute;n entre el polimorfismo del gen BDNF rs6265 y TEA [ p = .419, OR = 1.597 (.514, 4.967)]. Discusi&oacute;n y conclusi&oacute;n. A nivel mundial, los resultados de estudios de asociaci&oacute;n caso-control con el rs6265 de BDNF son controvertidos y no siempre se replican. Esto puede deberse a la etnicidad de nuestra poblaci&oacute;n y a otros factores no estudiados en el presente trabajo. El estudio sugiere que el SNP rs6265 no contribuye a la susceptibilidad al TEA en poblaci&oacute;n mexicana.</trans-abstract>
