Haplotype-based methods offer a powerful approach to disease gene mapping, based on the association between causal mutations and the ancestral haplotypes on which they arose. As part of The SNP Consortium Allele Frequency Projects, we characterized haplotype patterns across 51 autosomal regions (spanning 13 megabases of the human genome) in samples from(More)
We describe the Phase II HapMap, which characterizes over 3.1 million human single nucleotide polymorphisms (SNPs) genotyped in 270 individuals from four geographically diverse populations and includes 25-35% of common SNP variation in the populations surveyed. The map is estimated to capture untyped common variation with an average maximum r2 of between(More)
With the advent of dense maps of human genetic variation, it is now possible to detect positive natural selection across the human genome. Here we report an analysis of over 3 million polymorphisms from the International HapMap Project Phase 2 (HapMap2). We used 'long-range haplotype' methods, which were developed to identify alleles segregating in a(More)
Three molecular genetic techniques, restriction fragment length polymorphisms (RFLPs), random amplification of polymorphic DNA (RAPD), and allozyme variability, were used to evaluate the genetic diversity of two specific-pathogen-free (SPF) populations (numbers 1 and 2) and one candidate SPF population (number 4) of Penaeus vannamei developed and maintained(More)
The evolution of 5-aminolevulinate synthase (ALS) was studied by acquiring sequence data and generating phylogenetic trees. Gene sequences were already available for a variety of vertebrates (which have both a housekeeping and an erythroid form of the gene), fungi, alpha-proteobacteria, and one protist and one protostome. In order to generate representative(More)
Benzodiazepine receptor binding and open-field response were examined in male CD-1 mice after 6 weeks on a liquid diet providing either 36% ethanol or maltose-dextrin derived calories. In vivo binding of [3H]Ro15-1788, open-field activity and cortex and plasma concentrations were measured over a range of clonazepam doses (0.05-2.0 mg/kg). Mean +/- S.D. of(More)
The cDNA and inferred amino acid sequences were determined for beluga whale (Delphinapterus leucas) erythroid (E) and housekeeping (H) forms of 5-aminolevulinate synthase (ALS), and they were compared with known sequences for five other vertebrates with particular attention to regulatory features. The cDNAs for whale ALS-E and -H encode, respectively,(More)
