2008-04-14: HapMap Rel #23a available in HapMart
Genotypes, frequency and assay data for SNPs for release #23a (NCBI build 36, dbSNP b126) are now available for analysis through the HapMart utility. New platform and genotyping center implemented.
2008-04-01: HapMap Public Release #23a available
Genotypes and frequency data for this release are now available for bulk download and browsing.
Positional errors identified in previous release #23 have now been corrected. Please refer to the release notes for additional information.
2008-03-25: Genetic map for CEU and YRI available
Genome-wide recombination rates for CEU and YRI are now available for bulk download. A new genetic map including JPT+CHB data is expected to be released later in the year.
2008-03-06: Phased haplotypes for JPT+CHB under scrutiny
Phased haplotypes for JPT+CHB have been removed from public view. An announcement will be made when this has been sorted out.
2008-02-21: Incorrect position for merged SNPs in rel #23
The position of ~24,500 SNPs was inadvertently entered incorrectly in HapMap release #23 bulk files (genotypes and frequencies). A complete list of affected SNPs can be found here. Errors are being corrected and new genotypes and frequency files will be made available shortly under HapMap release #23a.
2008-02-06: HapMap inferred genotypes (rel#22)
Genotypes were inferred for 73 CEPH children using the method of Burdick et al. (Nat Genet 38:1002-4) and based on the genotypes of 60 CEPH individuals in the same families. Data and list of CEPH samples are available here.
2008-01-31: HapMap Public Release #23
Genotypes and frequency data for this release are now available for bulk download. These datasets include SNPs in the Affymetrix 6.0 array, as well as SNPs excluded from release #22 which have now been merged into new rs# identifiers in dbSNP 126 (NCBI b36). Lists of merged SNPs may be found here. Please refer to the release notes for additional information.
2007-12-20: Official release of HapMap Phased Haplotypes in NCBI b36 coordinates
HapMap release #22 phased autosomes are now available for bulk download.
2007-12-12: Genotype imputation using MACH1 software now available on HapMap Genome Browser
Impute genotypes for all HapMap SNPs in a given region by providing a subset of genotypes on HapMap SNPs. Browse a region of interest, upload your own data (Impute Data plugin), and modify the visualization of user-provided and imputed SNPs. MACH1 imputation available for release #21 (NCBI build 35).
