Does not interfere with Haploview data import. -reference/other allele notation in frequency files, replaces major/minor notation -Bad sample: the plate with Japanese and Chinese samples turned out to have a bad well, so the unreliable genotypes from sample NA18996 were discarded from release data dumps. Therefore genotypes are available for only 44 samples from the JPT population, instead of the planned 45. This sample may be replaced by another for phase II of the project, in which case all SNPs done up to that point in time will simply be missing data for the new sample. The HapMap database is updated monthly with data submitted to the DCC by centers funded by agencies in the UK, Japan, US, China and Canada. New frequency data are submitted to NCBI's dbSNP database within days and should become available also at http://www.ncbi.nih.gov/SNP/ soon thereafter, once NCBI has incorporated this submission into the next build of dbSNP. --------------------------------------- info@hapmap.org
