HapMap data release #22, March 2007, on NCBI B36 assembly, dbSNP b126   --

Genotypes and frequency data for SNPs remapped to NCBI build 36 (dbSNP b126) 
coordinates are available in this release.

A considerable number of SNPs with mapping inconsistencies from build 35 to 
build 36 were excluded in release #22.  The excluded SNPs fall in the various 
categories listed below and are available in the following directory:

http://www.hapmap.org/genotypes/2007-03/excluded_snps/

b36_dropped ==> SNPs with no position on B36. SNPs in this list will be 
included in future remappings.

b36_merged ==> SNPs merged into existing refSNP clusters. In future HapMap 
releases, genotypes for these SNPs will have been compared with those 
of their new rs#, and this will be acknowledged accordingly. Lists of merged 
SNPs can be obtained from dbSNP, see 
ftp://ftp.ncbi.nih.gov/snp/organisms/human_9606/database/organism_data

b36_chrom_pos_changed ==> SNPs with different chromosome positions. SNPs in 
this category will be included in HapMap release #22a.

b36_strand_changed ==> SNPs with strand flipped in the NCBI build 36.
