• Resumen

  • Recent decades have witnessed great methodological and technological advances in the genetic study of human diseases. These have not passed over research into the etiologies of neurodevelopmental disorders, including language disorders. However, the gap between molecular etiology and disease, in the case of language disorders in particular, is wide. One factor contributing to this is that the main disciplines that are involved in the endeavor to understand these conditions, namely, genetics, linguistics, language pathology, neurobiology, and developmental psychology, or, perhaps, researchers from those disciplines, do not necessarily speak the same language. This chapter aims to introduce, in relatively non-technical language, the basic concepts and methodologies of human genetics and genetic studies of diseases. Examples from major studies of developmental language disorders will be presented. Lastly, the use of genetics in the study of related neurodevelopmental disorders and their links with developmental language disorders will be evaluated, and future perspectives will be discussed.
