J., Rozemuller, Erik, Eikmans, Michael“…DNA from 171 mother‐child pairs (342 samples) was studied for: (a) HLA‐G allele information by the NGSgo‐AmpX HLA‐G assay, (b) 3′UTR haplotype information by an in‐house developed sequence‐based typing method of a 699/713 base pair region in the 3′UTR, and (c) the full phase HLA‐G gene sequence, by combining primers from both assays. The mother to child inheritance allowed internal verification of newly identified alleles and of association between coding and UTR regions. …”
