HumanHap550 Coverage of RefSeq Transcripts and
Exons
10
HumanHap550 SNP Locations RefSeq Genes
Coverage of transcripts/exons is higher when SNPs
outside exons/transcripts tagging SNPs inside
exons/transcripts are taken into account

SNPs in Known Copy Number Polymorphic Genomic
Regions
  • 4,317 SNPs from 495 regions included in
    HumanHap550
  • Regions were identified in 3 recent publications
  • Conrad, et al. (Nature Genetics 3875-81, 2006)
  • Hinds, et al. (Nature Genetics 3882-85, 2006)
  • McCarroll, et al. (Nature Genetics 3886-92,
    2006)
  • Proof these regions are actual CNV
  • 20X higher Mendelian inconsistency rate compared
    to the rest of HumanHap550 SNPs
  • Variations in log R ratios (intensity) in genomic
    profiles

Mitochondrial SNPs
  • Mitochondrial genome contains genes involved in
    metabolism and have been implicated in disease
    (i.e., Parkinsons Disease)
  • HumanHap550 is the only whole-genome genotyping
    product that contains mitochondrial SNPs
  • Selection criteria MAF 0.01 in European
    population, obtained from Broad Institute
    (http//www.broad.mit.edu/mpg/tagger/mito.html)
  • 177 mt SNPs on HumanHap550
  • Subset of 177 mtSNPs were observed to be
    polymorphic in each population
  • 46 SNPs in 33 unrelated CEU individuals
  • 48 SNPs in 29 unrelated CHB/JPT individuals
  • 60 SNPs in 26 unrelated YRI individuals
  • 21 major haplogroups defined in the mitochondrial
    genome by Hernstadt et al (2002)
  • 15 / 21 (71) of the major haplogroups are
    represented by haplogroup specific polymorphisms
    on HumanHap550
