Within this group, limbic encephalitis (antigens: LGI1, CASP2R), GPIHBP1 autoantibody syndrome (antigen: glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1), membranous nephropathy (antigens: PLA2R, THSD7A), and mucous membrane pemphigoid (antigen: laminin 332) have been described [12,18]. This evidence concerns the gene GPIHBP1 and mucous membrane pemphigoid.
