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.

Sensitive SNP dual-probe assays based on pyrene-functionalized 2'-amino-LNA: lessons to be learned.

TL;DR: A homogenous fluorescence dual‐probe assay containing 2′‐N‐(pyren‐1‐ylmethyl)‐2′‐amino‐LNA (locked nucleic acid) building blocks has been developed for effective mismatch‐sensitive nucleic Acid detection and highlights that conformational restriction combined with the use of short probes conveys favorable properties to dual‐ Probes.

Genetic Variation in Coding Regions Between and Within Commonly Used Inbred Rat Strains

TL;DR: The genetic variation between commonly used inbred rat strains is examined by using an efficient SNP discovery and typing assay based on enzyme-based (CEL I) heteroduplex cleavage and identifies 17 non-synonymous SNPs that may have an effect on protein function and contribute to phenotypic differences between different laboratory strains.

Matrix metalloproteinase (MMP) -2, -7 and -9 promoter polymorphisms in colorectal cancer in ethnic Kashmiri population - A case-control study and a mini review.

TL;DR: The results suggest that these MMP2, MMP7 and MMP9 promoter polymorphisms play a role as one of the key modulators of the risk of developing colorectal cancer in Kashmiri population.

DNMT3B Promoter Polymorphism and Risk of Gastric Cancer

TL;DR: Results showed that individuals with at least one -579G allele were also at significantly decreased risk of gastric cancer, and data suggested that DNMT3B genetic polymorphism varied among different races, ethnic groups, and geographic areas.

Analysis of similarity within 142 pairs of orthologous intergenic regions of Caenorhabditis elegans and Caenorhabditis briggsae

TL;DR: Overall, the patterns and characteristics identified here, along with other comparative and experimental studies, suggest that many footprints have a regulatory function, although other types of function are also possible.

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.
