The following directories contain project data that have been made publicly available. (See HapMap Data Access Policy for more information). More details about each dataset can be found in READMEs in the respective directories:

• Genotypes: Individual genotype data submitted to the DCC to date.
• LD Data: Linkage disequilibrium properties D', LOD , R² compiled from the genotype data to date
• Allocated SNPs: dbSNP reference SNP clusters that have been picked and prioritized for genotyping according to several criteria (see info on how SNPs were selected). The file 00README contains per-chromosome SNP counts and further details.
• Frequencies: Allele & genotype frequencies compiled from genotyping data submitted to the DCC to date. These have also been submitted to dbSNP and should be available in the next dbSNP build.
• SNP assays: Details about assays submitted to the DCC to date. PCR primers, extension probes etc., specific to each genotyping platform.
• Samples/individuals: Information on the samples used in the project and the individuals from which they were drawn. (See About the project: Which Populations are Being Sampled?).
• XML docs: Documentation on the XML format used in the project.

Release notes

HapMap data release #24, October 2008, on NCBI B36 assembly, dbSNP b126 --

This release contains genotypes and frequencies from phases I+II of the HapMap project. 
Allele flips for over 40,000 SNPs have been corrected, and over 1,600 chrX SNPs which 
were inadvertently dropped during the ncbi_b35 -> b36 migration, were added back. 

For a list of SNPs with allele flips corrected, see 
http://ftp.hapmap.org/genotypes/2008-10_phaseI+II/allele_flips_r23a.txt

ChrX SNPs added back in this data release are listed by population panel in
http://ftp.hapmap.org/genotypes/2008-10_phaseI+II/chrX_added_back/

For additional information, please see the accompanying README document:
