At present, the study of the variation at the genes involved in the pathogenesis of complex diseases is an approach that would enhance the accuracy of diagnosis and ensure appropriate treatment. At this aim we have performed an in-depth investigation on the Apolipoprotein E (APOE) gene in a sample of patients with sporadic late-onset Alzheimer's disease (AD) and related controls, in order to see whether any further variation in this gene could be associated with the onset of the disease. \n Our investigation revealed two different mutations in the exon 3 of the gene. One, the Leu28 \u00E0 Pro, was present in 5 of the 94 patients examined and in 1 of the 157 controls. The other, Thr42 \u00E0 Ala, was observed in only one AD patient, but in none of the controls.\nThe present results indicated that, compared with all the other APOE genotypes, those carrying the Leu28 \u00E0 Pro mutation were at a substantially higher risk of developing AD (OR = 10.95 ; 95% CI = 1.25 - 95.75 p = 0.015 ). \nThese results provide a useful tool to increase the precision of an early diagnosis. In this way, any therapy could be initiated early in time, with potential advantages for curing the disease."^^xsd:string ; skos:note "ISI Web of Science (WOS)"^^xsd:string ; pubblicazioni:affiliazioni "1.

One, the Leu28Pro, always found on an APOE e*4 allele, was present in 5 of the 94 patients and in 1 of the 157 controls. The other, Thr42Ala, found on an e*3 allele, was observed in only one AD patient, who also carried the Leu28Pro, but in none of the controls.\n In the AD patient group the allele e*4 -, corresponding to Leu28Pro, showed a frequency of 0.027, compared with only 0.003 in the controls. Compared to E3/3 and E3/2 genotypes, the risk of developing AD associated with the genotypes carrying the e*4 allele, the well-established risk allele for AD onset, was observed to be high (OR = 3.16; 95% CI = 1.62 - 6.20 ; p = 0.0009 ), but the risk associated with genotypes carrying the Leu28 \u00E0 Pro mutation was higher still (OR = 10.95 ; 95% CI = 1.25 - 95.75 p = 0.015 ). The higher risk associated with this mutation was assessed by meta-analysis carried out using the data of three patient groups from a previously published study (Kamboh et al. 1999) and from our study. The results indicated that, compared with all the other APOE genotypes, those carrying the Leu28Pro mutation were at a substantially higher risk of developing AD (OR = 4.25, 95% CI = 1.21 - 14.97)." ; prodottidellaricerca:prodottoDi istituto:CDS013 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA19796 . @prefix parolechiave: . prodotto:ID11295 parolechiave:insiemeDiParoleChiave . ns10:ID417115 pubblicazioni:rivistaDi prodotto:ID11295 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID11295 .
