Two approaches were used to correlate the Aedes aegypti genetic linkage map to the physical map. STS markers were developed for previously mapped RFLP-based genetic markers so that large genomic clones from cosmid libraries could be found and placed to the metaphase chromosome physical maps using standard FISH methods. Eight cosmids were identified that contained eight RFLP marker sequences, an...
A few linkage maps of tea have been constructed using pseudo-testcross theory based on dominant marker systems. However, dominant markers are not suitable as landmark markers across a wide range of materials. Therefore, we developed co-dominant SSR markers from genomic DNA and ESTs and constructed a reference map using these co-dominant markers as landmarks. A population of 54 F(1) clones deriv...
We report construction of a comparative linkage map for the mosquito (Culex pipiens) based on restriction fragment length polymorphisms (RFLPs) using cDNA clones from Aedes aegypti as probes to Southern blots of Cx. pipiens genomic DNA. Seventy-one cDNA clones were screened for hybridization and genetic diversity among three Cx. pipiens strains. Fifty-two of 71 cDNA clones, isolated from and pr...
During the past decade, considerable efforts and resources have been devoted to elucidating the multiple genetic and environmental determinants responsible for hypertension and its associated cardiovascular diseases. The success of positional cloning, fine mapping, and linkage analysis based on whole-genome screening, however, has been limited in identifying multiple genetic determinants affect...
In some species, meiotic recombination is concentrated in small genomic regions. These "recombination hotspots" leave signatures in fine-scale patterns of linkage disequilibrium, raising the prospect that the genomic landscape of hotspots can be characterized from sequence variation. This approach has led to the inference that hotspots evolve rapidly in some species, but are conserved in others...
A family history of disease is a strong risk factor for testicular germ cell tumour (TGCT). In order to identify the location of putative TGCT susceptibility gene(s) we conducted a linkage search in 237 pedigrees with two or more cases of TGCT. One hundred and seventy-nine pedigrees were evaluated genome-wide with an average inter-marker distance of 10 cM. An additional 58 pedigrees were used t...
PURPOSE To determine clinical phenotypes, evolution and genetic background of a large family with a combination of two unusual forms of reflex epilepsies. METHOD Phenotyping was performed in eighteen family members (10 F, 8 M) including standardized EEG recordings with intermittent photic stimulation (IPS). Genetic analyses (linkage scans, Whole Exome Sequencing (WES) and Functional studies) ...
In nonrecombining genomes, genetic linkage can be an important evolutionary force. Linkage generates interference interactions, by which simultaneously occurring mutations affect each other's chance of fixation. Here, we develop a comprehensive model of adaptive evolution in linked genomes, which integrates interference interactions between multiple beneficial and deleterious mutations into a u...
This thesis investigates techniques for the discovery and use of phase information in genetic studies. ``Phase'' refers to the precise assignment of the members of a different base pairs at the same genomic locus to two possible candidate homologous chromosomes. This ``missing'' information is usually not available in most genetic studies. We investigate the importance of phase information in l...
Mutation of the Bloom's syndrome (BS) gene, BLM, results in genomic instability. As the first step toward positional cloning of the gene, tight linkage of BLM and FES at 15q26.1 was detected by genotyping affected in families in which the parents are cousins, so-called homozygosity mapping. Linkage disequilibrium between BLM and FES was detected in Ashkenazi Jews with BS, confirming the linkage...
