A popular method for the analysis of case-control association studies is to compare the frequencies of the alleles between cases and controls by means of Pearson's chi2-statistic. Here, an approach for computing the power of this test is presented, which by computer simulation is shown to be more reliable than a previously published power approximation.(More)
Notch3 mutations cause CADASIL, an increasingly recognized cause of subcortical ischemic stroke and vascular dementia in human adults. In the absence of any specific diagnostic criteria, CADASIL diagnosis is based on mutational scanning of Notch3, which is a large gene composed of 33 exons with a high G-C content. In this study we examined the sensitivity(More)
Hepatitis C virus (HCV) treatment is based on the association of pegylated alpha interferon (IFN-alpha) and ribavirin. To improve the level of sustained virological response to treatment, especially in patients infected with HCV genotype 1, new IFNs with improved efficacy and toxicity profiles may be developed. In this report, we show that, in the BM4-5(More)
As the largest set of sequence variants, single-nucleotide polymorphisms (SNPs) constitute powerful assets for mapping genes and mutations related to common diseases and for pharmacogenetic studies. A major goal in human genetics is to establish a high-density map of the genome containing several hundred thousand SNPs. Here we assayed 3.7 Mb (154,397 bp in(More)
Due to the surge in interest in using single nucleotide polymorphisms (SNPs) for genotyping a facile and affordable method for this is an absolute necessity. Here we introduce a procedure that combines an easily automatable single tube sample preparation with an efficient high throughput mass spectrometric analysis technique. Known point mutations or single(More)
