ABSTRACT
La elevada prevalencia de la enfermedad de Alzheimer (EA), junto con la posibilidad de nuevas pautas en el diagnóstico mediante el empleo de los biomarcadores está cambiando el enfoque de los ancianos con demencia o en riesgo de padecerla. En este sentido parece importante revisar los aspectos genéticos de los ancianos con EA familiar, así como los ancianos con riesgo de padecer EA. La amplia difusión de los estudios genéticos asociados a esta afección también puede ser de gran ayuda. Además de los genes del amiloide, las presenilinas y la apolipoproteína E, implicados en la patogenia de la EA, debemos añadir otros genes recientemente relacionados con la enfermedad entre los que destacan el gen de la clusterina y los de fosfatidil-inositol de unión a clatrina y el del receptor de la proteína del complemento C3b(AU)
The high prevalence of Alzheimer's disease, along with the possibility of new approaches in diagnosis through the use of biomarkers of cerebrospinal fluid is shifting the focus to the elderly with dementia or at risk. In this sense it seems important to review the genetic aspects of the elderly with familial Alzheimer's disease as well as those at risk. The wide distribution of genetic studies associated with this condition may also be helpful. To the classical findings of the genes for amyloid, the presenilins and apolipoprotein E, we must add other genes recently implicated in the pathogenesis of the disease, among which are found the clusterin gene, encoding the phosphatidyl-inositol-binding clathrin assembly protein gene, and the receptor for the complement C3b protein(AU)
