Tag SNP selection in genotype data for maximizing SNP prediction accuracy
MOTIVATION The search for genetic regions associated with complex diseases, such as cancer or Alzheimer's disease, is an important challenge that may lead to better diagnosis and treatment. The existence of millions of DNA variations, primarily single nucleotide polymorphisms (SNPs), may allow the fine dissection of such associations. However, studies seeking disease association are limited by ...
متن کاملHaplotype block partitioning and tag SNP selection using genotype data and their applications to association studies.
Recent studies have revealed that linkage disequilibrium (LD) patterns vary across the human genome with some regions of high LD interspersed by regions of low LD. A small fraction of SNPs (tag SNPs) is sufficient to capture most of the haplotype structure of the human genome. In this paper, we develop a method to partition haplotypes into blocks and to identify tag SNPs based on genotype data ...
متن کاملTag SNP selection via a genetic algorithm
Single Nucleotide Polymorphisms (SNPs) provide valuable information on human evolutionary history and may lead us to identify genetic variants responsible for human complex diseases. Unfortunately, molecular haplotyping methods are costly, laborious, and time consuming; therefore, algorithms for constructing full haplotype patterns from small available data through computational methods, Tag SN...
متن کاملA Set of Dynamic Programming Algorithms for Haplotype Block Partitioning and Tag SNP Selection via Haplotype Data or Genotype Data
Recent studies have revealed a haplotype block structure for human genome such that it can be decomposed into large blocks with high linkage disequilibrium (LD) and relatively limited haplotype diversity, separated by short regions of low LD. One of the practical implications of this observation is that only a small number of tag SNPs can be chosen for mapping genes responsible for human comple...
متن کاملLinear reduction method for predictive and informative tag SNP selection
Constructing a complete human haplotype map is helpful when associating complex diseases with their related SNPs. Unfortunately, the number of SNPs is very large and it is costly to sequence many individuals. Therefore, it is desirable to reduce the number of SNPs that should be sequenced to a small number of informative representatives called tag SNPs. In this paper, we propose a new linear al...
