Sodium-dependent phosphate transport protein 2B

The SLC34A2 gene encodes a a sodium-phosphate transporter that is predominantly expressed in alveolar epithelial cells type 2 but also found in various other tissues including mammary gland, and to a lesser extent in intestine, kidney, skin, prostate and testes. Mutations cause autosomal recessive pulmonary alveolar microlithiasis.
