Chromosome 19p in Alzheimer's disease: when genome meets transcriptome.

Genetic studies have identified several genomic loci including chr19p13.2 relevant to Alzheimer's disease (AD) susceptibility. However, the functional roles of these genomic loci in AD pathogenesis require further clarification. Transcriptome as an endophenotype is critical for the understanding of disease mechanism. Here we demonstrate that chr19p is the most significantly perturbed chromosome region in AD brain transcriptome. With dual evidence from genome and transcriptome, chr19p likely play a special role in AD pathogenesis.
