Accurate estimation of homologue-specific DNA concentration-ratios in cancer samples allows long-range haplotyping
Interpretation of allelic copy measurements at polymorphic markers in cancer samples presents distinctive challenges and opportunities. Due to frequent gross chromosomal alterations occurring in cancer (aneuploidy), many genomic regions are present at homologus-allele imbalance. Within such regions, the unequal contribution of alleles at heterozygous markers allows for direct phasing of the hap...
متن کاملDirect molecular haplotyping of long-range genomic DNA with M1-PCR.
Haplotypes, combinations of several phase-determined polymorphic markers, are extremely valuable for studies of disease association and chromosome evolution. Here we describe a technique called M1-PCR (M for "multiplex" and 1 for "single-copy DNA molecules") that enables direct molecular haplotyping of several polymorphic markers separated by as many as 24 kb. A genomic DNA sample first is dilu...
متن کاملMolecular haplotyping of genetic markers 10 kb apart by allele-specific long-range PCR.
Haplotypes, combinations of polymorphic markers in a chromosome, are critical for genome diversity research. However, their utility in population samplings is compromised by uncertain linkage phase determinations from unrelated individuals. Molecular haplotyping accomplishes direct phase determination by generation of hemizygous templates from diploid genomic samples. We report molecular haplot...
متن کاملDetection of Somatic Mutation in Exon 12 of DNA Polymerase β in Ovarian Cancer Tissue Samples
Background: DNA polymerase β (pol β) is a key enzyme of base excision repair pathway. It is a 1-kb gene consisting of 14 exons. Its catalytic part lies between exon 8 and exon 14. Exon 12 has a role in deoxyribonucleotide triphosphate selection for nucleotide transferase activity. Methods: Genomic DNA was isolated from ovarian carcinoma samples. Single strand conformation polymorphism...
متن کاملDetermination of 40K concentration in milk samples consumed in Tehran-Iran and estimation of its annual effective dose
Background: Since 40K is the most important natural radionuclide in the environment, its concentration was measured for all milk and milk powder samples consumed in Tehran-Iran. Milk was chosen, since because it is a reliable indicator of the general population intake of certain radionuclide, and many environmental programs have been applied for its safety. Materials and Methods: Measu...
