Large-Scale Identification, Mapping, and Genotyping of Single-Nucleotide Polymorphisms in the Human Genome

TLDR
A large-scale survey for SNPs was examined by a combination of gel-based sequencing and high-density variation-detection DNA chips, and a genetic map was constructed showing the location of 2227 candidate SNPs.
Abstract
Single-nucleotide polymorphisms (SNPs) are the most frequent type of variation in the human genome, and they provide powerful tools for a variety of medical genetic studies. In a large-scale survey for SNPs, 2.3 megabases of human genomic DNA was examined by a combination of gel-based sequencing and high-density variation-detection DNA chips. A total of 3241 candidate SNPs were identified. A genetic map was constructed showing the location of 2227 of these SNPs. Prototype genotyping chips were developed that allow simultaneous genotyping of 500 SNPs. The results provide a characterization of human diversity at the nucleotide level and demonstrate the feasibility of large-scale identification of human SNPs.

An introduction to DNA chips: principles, technology, applications and analysis.

TL;DR: GeneChip technology is described that provides efficient access to genetic information using miniaturised, high-density arrays of DNA or oligonucleotide probes that has been successfully applied to investigate simultaneous expression of many thousands of genes and to the detection of mutations or polymorphisms.

DNA Sequence Evolution with Neighbor-Dependent Mutation

TL;DR: In this paper, a non-equilibrium model of DNA sequence evolution is proposed to account for biases in mutation rates that depend on the identity of the neighboring bases, and a web-based tool has been constructed to compute single and dinucleotide frequencies for arbitrary neighbor-dependent mutation rates.

The birth and death of human single-nucleotide polymorphisms: new experimental evidence and implications for human history and medicine

TL;DR: Interesting observed genomic patterns include SNP deserts (regions of low SNP incidence) and lengthy regions of linkage disequilibrium containing only a few haplotypes.

Methods for disease detection

TL;DR: In this article, the authors presented methods for detecting disease by analysis of a patient sample to determine the integrity of nucleic acids in the sample, which was used to determine whether the nucleic acid integrity was compromised or not.

Light-generated oligonucleotide arrays for rapid DNA sequence analysis

TL;DR: It is reported here how modern photolithographic techniques can be used to facilitate sequence analysis by generating miniaturized arrays of densely packed oligonucleotide probes, which can then be applied to parallel DNA hybridization analysis, directly yielding sequence information.

Extensive polymorphisms observed in HIV–1 clade B protease gene using high–density oligonucleotide arrays

TL;DR: In the first clinical application of high–density oligonucleotide arraysequencing, the sequences of 167 viral isolates from 102 patients have been determined and the DNA sequence of USA HIV–1 clade B proteases was found to be extremely variable.

Detection of heterozygous mutations in BRCA1 using high density oligonucleotide arrays and two-colour fluorescence analysis.

TL;DR: Fourteen of fifteen patient samples with known mutations were accurately diagnosed, and no false positive mutations were identified in 20 control samples, suggesting DNA chip–based assays may provide a valuable new technology for high–throughput cost–efficient detection of genetic alterations.

The use of a genetic map of biallelic markers in linkage studies

TL;DR: How polymorphic and densely spaced biallelic markers need to be for extraction of most of the inheritance information from human pedigrees is examined, and a map of 700–900 moderately polymorphic bialLElic markers is concluded to be equivalent to the current 300–400 microsatellite marker sets.
