Alleles of the Apolipoprotein E (ApoE) gene are known to modulate the genetic risk for developing late-onset Alzheimers disease (AD). While the presence of ApoE ε4 allele is a major genetic risk factor for the development of late onset AD, the possession of the ε2 allele has been suggested to confer a protective effect against the disease. On a cohort of more than 500 young healthy adolescents this TBSS study found no differences in white matter microstructural organisation between carriers and non-carriers of the ApoE ε4 and ε2 alleles suggesting that effects of these alleles may emerge later in life.
