For mothers with a previous history of GDM, significant inverse correlation was found between level of I-FABP and level of IgA to B. adolescentis strain DSM20083 (r=-0.68; p=0.0013), as well as to B.adolescentis strain DSM20086 (r=-0.72; p=0.0005). This evidence concerns the gene CD79A and gestational diabetes.
