In this context, some research groups have studied the glycobiome patterns in the breast milk of mothers with GDM, it was found that [53], compared to healthy women, the content of free oligosaccharides in the breast milk of GDM women was not different, but the total protein concentration and glycosylation level of sIgA in GDM breast milk were reduced; in contrast, the glycosylation of lactoferrin in the milk of GDM mothers was increased compared with the breast milk of healthy control mothers. This evidence concerns the gene LTF and gestational diabetes.
