From: HLA-G DNA sequence variants and risk of perinatal HIV-1 transmission

Figure 1

Sequence electropherograms obtained from HLA-G DNA 5' untranslated regulatory region showing polymorphisms at nucleotide positions 634 and 714. A-B: Reverse strand sequences and arrows indicating a nucleotide change of Cā†’G observed between mother-child pairs among the HIV-1 non-transmitting group. C-D: Forward strand sequences showing insertions of either T or G. E: Reverse strand sequence and underlined is the CCAAT box. Interestingly, dissimilarities of the 714insT/G were observed between the mother child pairs of the HIV-1-non-transmitting group while, either 714insG/G or mother-child pairs with similar nucleotide changes were observed among the transmitting group.
