FLG and Eczematoid dermatitis: There is evidence in the literature for transmission of peanut allergen in utero or via breastmilk (Vadas et al., 2001; DesRoches et al., 2010), as well as early sensitisation via home environmental exposure, especially in those with concurrent eczema or a predisposing filaggrin (FLG) mutation that may allow transcutaneous infiltration of allergen (Brough et al., 2013; Brough et al., 2014).
