Summary: Research over the last few years has revealed significant haplotype structure in the human genome. The characterization of these patterns, particularly in the context of medical genetic association studies, is becoming a routine research activity. Haploview is a software package that provides computation of linkage disequilibrium statistics and population haplotype patterns from primary genotype data in a visually appealing and interactive interface.

| INTRODUCTION |
|---|
|
|
|---|
Knowledge of local linkage disequilibrium (LD) and common haplotype patterns in disease association and positional cloning studies is becoming increasingly widespread since it has become clear (Van Eerdewegh et al., 2002; Rioux et al., 2001; Geesaman et al., 2003; Stoll et al., 2004) that intelligent use of this information has the potential to make them much more comprehensive and efficient. Early studies identifying unexpected extent of correlation and structure in haplotype patterns (Reich et al., 2001; Daly et al., 2001; Gabriel et al., 2002) have led to the initiation of the Human Haplotype Map project (HapMap) to make this information available to all medical genetics researchers (International HapMap Consortium, 2003). Given the dramatic increase in the size and number of disease association studies worldwide and the enormous amount of public genotype data from HapMap, tools for analyzing, interpreting and visualizing these data are of critical importance to researchers everywhere.
Haploview is designed to provide a comprehensive suite of tools for haplotype analysis for a wide variety of dataset sizes. Haploview generates marker quality statistics, LD information, haplotype blocks, population haplotype frequencies and single marker association statistics in a user-friendly format. All the features are customizable and all computations performed in real time, even for datasets with hundreds of individuals and hundreds of markers.
| FEATURES |
|---|
|
|
|---|
Haploview accepts input in a variety of formats. Pedigree data can be loaded as either partially or fully phased chromosomes or as unphased diplotypes in the standard Linkage format. The latter format also allows the user to specify family structure information as well as disease affection or case/control status. Marker information, including name and location is loaded separately. Haploview also directly accepts genotype data dumped from the Human HapMap website (http://www.hapmap.org). A graphical genome browser maintained at that site allows researchers to navigate to a particular region of the genome and dump HapMap genotype data for all genotyped markers in the selected region in a format accepted by Haploview.
Upon loading a dataset, the software presents to the user a series of marker genotyping quality metrics. These include a check for conformance with HardyWeinberg equilibrium, a tally of Mendelian inheritance errors and the percentage of individuals successfully genotyped for that marker. The program filters out markers which fall below a preset threshold for these tests. The user can adjust these thresholds as well as handpick markers to add or remove from the subsequent steps. At any time later in the process, the user may return to this quality control panel, add or remove additional markers, and have the changes immediately reflected in the ongoing analyses.
Haploview calculates several pairwise measures of LD, which it uses to create a graphical representation (Fig. 1). The user has the option to select one of several commonly used block definitions (Gabriel et al., 2002; Wang et al., 2002) to partition the region into segments of strong LD. Alternatively, the user may manually select groups of markers for subsequent haplotype analysis. This view also allows a number of different color schemes to represent the LD relationships. Further, the program allows the display of an analysis track above the LD plot, to display continuous variables such as recombination rate estimates (McVean et al., 2004) (Fig. 1).
|
Once groups of markers are selected (either automatically or manually), the program generates haplotypes and their population frequencies (Fig. 1). This display shows lines to indicate transitions from one block to the next with frequency corresponding to the thickness of the line and also presents Hedrick's multiallelic D', which represents the degree of LD between two blocks, treating each haplotype within a block as an allele of that region. Again, customization is available for nearly all aspects of the display, including displaying alleles as letters, numbers or colored boxes and displaying only those haplotypes above an adjustable threshold in the population.
If affection status is included in the input file, Haploview also calculates the standard TDT statistic (for trio data) or simple
2 (for case/control data) for each marker that can be used for association studies. Future versions will include several haplotype-tag SNP selection methods as well as haplotype-based association testing and evaluation of significance using permutation testing. These final features allow the user to go from raw genotype data through exploring genetic associations in one easy to use software package. Haploview is maintained as an open source project (http://sourceforge.net/projects/haploview/), which allows external parties to add their own methods in addition to the continuing development by the authors.
Each of these views of the data is shown on a separate tab (Fig. 1), allowing the user to move from one to the next, with interactive modifications made by the user in any panel reflected in all the others. For example, one can return at any time to the review of marker quality and manually include or exclude individual markersthese changes are instantly reflected in the LD and haplotype panels. This provides the ability to analyze the data in real-time. The information on each panel is also able to be exported to a PNG for use in presentations or publications or dumped to a text file. Additionally, the program has a fully functional command-line mode, which allows users to run all the analyses without opening the GUI on one or more files at once.
| IMPLEMENTATION |
|---|
|
|
|---|
Haploview is written entirely in Java, which means it is usable on any platform with Java 1.3 or later installed. Running on a 1.8 GHz Pentium 4 with 1 GB of RAM, Haploview can display a dataset with 200 markers genotyped in 400 individuals and adjust parameters with no noticeable delay. The program is also able to be used (from the command line) to do the LD calculations on very large datasets in comparatively small amounts of time. Haploview was able to compute 3.3 million pairwise LD values (comparisons of all markers closer than 500 KB in a 45 500 marker dataset) in 30 min.
Haploview uses a two marker EM (ignoring missing data) to estimate the maximum-likelihood values of the four gamete frequencies, from which the D', LOD and r 2 calculations derive. Haplotype phase and population frequency are inferred using a standard EM algorithm with a partitionligation approach for blocks with greater than 10 markers. Conformance with HardyWeinberg equilibrium is computed using an exact test (G.Abecasis and J.Wigginton, personal communication).
