The overall purpose of this study was to demonstrate the feasibility of producing haplotype-phased whole genome sequence data from a fetus using free fetal DNA isolated from maternal plasma collected during the first half of gestation.
We performed a second-generation genome-wide association study of 4,533 individuals with celiac disease (cases) and 10,750 control subjects. We genotyped 113 selected SNPs with P(GWAS) < 10(-4) and 18 SNPs from 14 known loci in a further 4,918 cases and 5,684 controls. Variants from 13 new regions r...
