Autismo, Alteraciones cromosómicas, Cromosoma Y largoResumen
Cada vez es mayor la evidencia de que factores orgánicos son relevantes en la etiología del autismo infantil. Diversos hallazgos sugieren una relación, aún no claramente establecida, entre el autismo y anomalías cromosómicas (X frágil, XXY, Y isodicéntrico e Y largo).
El presente trabajo aporta tres nuevos casos de autismo asociado a un cromosoma Y largo (Yq+), y demuestra similares alteraciones en el cariotipo de los padres varones de estos pacientes.
Se discute la implicación de estos hallazgos en la comprensión etiológica del autismo infantil.
