2.A.53.2.1
Sulfate/anion transporter (diastrophic dysplasia protein) (SLC26A2). It catalyzes electroneutral SO4-, OH- and Cl- exchange, regulated by extracellular Cl- (Ohana et al., 2011). Congenital chloride diarrhea and inherited skeletal dysplasias are observed in patients with SLC26A2 mutations (Sun et al. 2021). Biji et al. 2022 have expanded the spectrum of SLC26A2-related lethal chondrodysplasia and reported three novel variants correlating clinical severity and protein phenotype within the lethal spectrum of this rare dysplasia.
