The UDP-glucuronic acid/UDP-N-acetylgalactosamine transporter (SLC35D1) transports both UDP-glucuronic acid (UDP-GlcA) and UDP-N-acetylgalactosamine (UDP-GalNAc) from the cytosol into the ER lumen across the ER membrane. Defects in SLC35D1 can cause Schneckenbecken dysplasia (SCHBCKD; MIM:269250), a rare, autosomal recessive, lethal short-limbed skeletal dysplasia. Mutations that can cause SCHBCKD include K42Sfs*10, W311*, R107* and T65P (Hiraoka et al. 2007, Furuichi et al. 2009).
