Description of data contents
Genotype data (876K SNPs, 87 samples). Essentially the same as described in Kukita et al. paper (2010), except that two additional samples (CHM010 and CHM035) were included. No CNV information is included in the download data.

Data acquisition method

Genotypes were determined using Affymetrix SNP 6.0 arrays

Data analysis method

A hundred complete hydatidiform moles (CHMs) were genotyped using Affymetrix SNP Array 6.0, and mapped on the human reference genome sequence, NCBI Build 36. Low log2R calls, calls judged to be in deleted regions (determined by CNV analysis), and heterozygous calls were forced to no calls, as described in Kukita et al. 2010. After QCs by sample call rate and SNP call rate, the final data for 87 CHMs (876K SNPs) was obtained.
