The baseline characteristics of the kids were similarly distributed between the intervention groups, apart from homozygosity for HLA-DQ2 . Data on breast-feeding were available for 943 children: 882 started breast-feeding; at six months old, 527 were breast-fed, and 265 were breast-fed without complementary feeding except for the intervention product. Of the 455 moms with celiac disease, 431 were consuming a gluten-free diet during lactation and being pregnant. Rotavirus vaccination was performed in 211 children , either prior to the intervention or during the intervention .The variant in a woman’s genome, which causes errors in the cell replication process, is strongly associated with risk of aneuploidy – – an abnormal number of chromosomes in a cell, the researchers said. However they did not demonstrate that the variant causes pregnancy problems. Early in human development, this [cell replication] procedure is specially error-prone, affecting as much as 75 % of embryos and often causing pregnancy loss as soon as five days after fertilization – – before the mother actually knows she actually is pregnant, study initial author Rajiv McCoy, a postdoctoral researcher at the University of Washington in Seattle, said in a news launch from the American Culture of Human Genetics.
