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.

A DNA Polymorphism Discovery Resource for Research on Human Genetic Variation

TL;DR: A large number of mapped SNPs will be valuable as markers throughout the genome for finding SNPs that do affect gene function, as linkage disequilibrium over tens to hundreds of kilobases is expected to be found in many regions of the human genome.

Genetic and physiological data implicating the new human gene G72 and the gene for D-amino acid oxidase in schizophrenia.

TL;DR: A map of 191 single-nucleotide polymorphism (SNPs) was built across a 5-Mb segment from chromosome 13q34 that has been genetically linked to schizophrenia, pointing to the involvement of this N-methyl-d-aspartate receptor regulation pathway in schizophrenia.

Denaturing high-performance liquid chromatography: A review.

TL;DR: The utility of DHPLC has been extended to the genotyping of known polymorphisms by utilizing the ability of poly(styrene‐divinylbenzene) to resolve single‐stranded DNA molecules of identical size that differ in a single base.

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.
