The table lists all SMAD-regulated components of the TGFβ signaling pathway and associated monogenic diseases. Components with no identified association are (ACVR1B, ACVR1C, ACVR2A, TGFBR3, INHBA, Inhibin subunits A, B, BB and C, BMP 3, 5, 6, 7 and 10, GDF7, SMAD 1, 2, 5 and 7). Genetic diseases found to have a possible ERAD pathology are denoted with an asterisk*. AR, autosomal recessive; AD, autosomal dominant.
