DNA mutation analysis of Gaucher patients

American Journal of Medical Genetics, 1992
AbstractWe evaluated 62 Gaucher patients to determine whether patients with similar phenotypes had the same DNA point mutations. Genomic DNA from these Gaucher patients was screened for the 3 most frequent single‐point mutations, occurring in 69% of the 124 patient alleles, and resulting in changes in amino acids 370, 444, and 463.

Mutational analysis of archaeal histone-DNA interactions

Journal of Molecular Biology, 2000
Site-specific mutagenesis of the hmfB gene cloned from the archaeon Methanothermus fervidus, followed by expression in Escherichia coli, has been used to generate approximately 90 recombinant (r) variants of the archaeal histone HMfB. The abilities of these variants to form stable archaeal nucleosome-containing complexes with linear pBR322 DNA, and ...

Somatic DNA Mutation Analysis

2017
Somatic mutations in patient tumor DNA samples can be readily detected based on mass spectrometry. The MassARRAY system is a high-throughput matrix-assisted laser desorption time-of-flight (MALDI) mass spectrometer for detection of nucleic acids. The technique is based on single-nucleotide base extension.

Analysis of Mitochondrial DNA Mutations: Point Mutations

2003
Since the first demonstration that mutations of the mitochondrial genome were associated with human disease, more than 100 pathological mitochondrial DNA (mtDNA) defects have been characterized in patients with a broad spectrum of clinical manifestations (1). Single-point mutations, involving either protein-encoding genes or more commonly RNA (rRNA and

Analysis of Mitochondrial DNA Mutations: Deletions

2003
Although the precise mechanisms of the aging process remain poorly understood, a plausible theory for cellular dysfunction and deterioration during aging involves mitochondria (1, 2). The major function of mitochondria is to generate energy for cellular processes in the form of ATP by oxidative phosphorylation. Mitochondria contain their own DNA (mtDNA)

Mutation identification DNA analysis system (MIDAS) for detection of known mutations

Electrophoresis, 1999
We introduce a novel experimental strategy for DNA mutation detection named the Mismatch Identification DNA Analysis System (MIDAS) [1, 2], which has an associated isothermal probe amplification step to increase target DNA detection sensitivity to attomole levels.

Mutation Surveyor: Software for DNA Sequence Analysis

2010
Advances in high-throughput sequencing techniques had presented a significant challenge to the processing capabilities of genetic laboratories. However, recent developments in the field of semi-automated mutation detection have revolutionised the task of mutation detection.This chapter provides user information for one commercially available program ...

Point mutation analysis of archived cytogenetic slide DNA

Cytogenetic and Genome Research, 1996
Archived Giemsa-stained cytogenetic slide repositories represent valuable DNA resources for medical, scientific, and forensic studies. Sequencing readily identified a Charcot-Marie-Tooth disease point mutation in a 209-bp PCR amplified product. With optimal PCR primers and amplification conditions, our protocol quickly and reliably isolated sufficient ...

DNA mutation detection and analysis using miniaturized microfluidic systems

Expert Review of Molecular Diagnostics, 2006
Identification of genetic sequence variations occurring on a population-wide scale is key to unraveling the complex interactions that are the underlying cause of many medical disorders and diseases. A critical need exists, however, for advanced technology to enable DNA mutation analysis to be performed with significantly higher throughput and at ...

DNA microarray analysis of fim mutations in Escherichia coli

Molecular Genetics and Genomics, 2002
Bacterial adhesion is often mediated by complex polymeric surface structures referred to as fimbriae. Type 1 fimbriae of Escherichia coli represent the archetypical and best characterised fimbrial system. These adhesive organelles mediate binding to D-mannose and are directly associated with virulence in the urinary tract.
