DSG2 and hydrops fetalis: DSG2 relative mRNA expression in jejunal tissue was lower in the CG.M group than in the CG group (0.47 ± 0.16 versus 0.98 ± 0.29; P = 0.003), in the HF.M group than in the HF group (0.20 ± 0.09 versus 1.81 ± 0.32; P < 0.001), and in the RDN.M group than in the RDN group (0.55 ± 0.10 versus 1.06 ± 0.27; P = 0.002) (Fig. 4D).
