Alzheimer's disease (AD) is the most common form of dementia. To date, more than 200 mutations in three genes have been identified as cause of early-onset autosomal dominant inherited AD. The aim of this study was to characterize the mutation spectrum and describe genotype-phenotype correlations in Serbian patients with positive family history of AD or/and early-onset AD. We performed a genetic screening for mutations in the coding regions of Presenilins 1 and 2 (PSEN1 and PSEN2), as well as exons 16 and 17 of the Amyloid Precursor Protein gene (APP) in a total of 47 patients from Serbia with a clinical diagnosis of familial and/or early-onset AD (mean age at onset of 60.3 years; range 32-77). We found one novel mutation in PSEN1, one novel variant in PSEN2, and three previously described variants, one in each of the analyzed genes. Interestingly, we identified one patient harboring two heterozygous mutations: one in APP (p.L723P) and one in PSEN1 (p.R108Q). (C) 2012 Elsevier Inc. All rights reserved.
