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.

Protein expression profiling

TL;DR: In this article, a rolling circle replication primer is associated with the various proteins using a conjugate of the primer and a molecule that specifically binds the proteins to be detectable, which results in production of a large amount of DNA at the sites in the array where the proteins are immobilized.

Sex Differences in Kappa Opioid Receptor Function and Their Potential Impact on Addiction

TL;DR: Evidence that the function of DYN-KOR systems is influenced in a sex-dependent manner by polymorphisms in the prodynorphin gene, genetic linkage with the melanocortin-1 receptor (MC1R), heterodimerization of KORs and mu opioid receptors (MORs), and gonadal hormones is highlighted.

Putative SNP discovery in interspecific hybrids of catfish by comparative EST analysis.

TL;DR: The majority of identified SNPs differed between the two species and, therefore, these SNPs are useful for mapping genes in channel catfish x blue catfish interspecific resource families.

Polymorphism analysis and gene detection by minisequencing on an array of gel-immobilized primers.

TL;DR: Two procedures, multibase and multiprimer, have been developed for single nucleotide extension of primers immobilized within polyacrylamide gel pads on a microchip for diagnosis of beta-thalassemia mutations.

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.
