This summary table identifies variations with respect to the National Center for Biotechnology Information (NCBI) version 36 human genome reference assembly. Novel variations were ascertained by comparison to dbSNP (JDW, release 126; NA18507 [Bentley], release 128; all other genomes, release 129). NA18507 and NA19240 are Yoruban HapMap samples, which may explain the number of SNPs and novelty rates. In partially called regions of the genome, only one allele could be called confidently. The high call rate in NA19240 reflects reduced library bias with a modified sample preparation protocol.
