The human gene SLC29A3 encodes the equilibrative nucleoside transporter 3 (ENT3). It is abundant in many tissues, especially the placenta and is localized intracellularly on the lysosomal membrane. SLC29A3 mediates the reversible transport of nucleosides as well as anticancer and antiviral agents such as cladribine, cordycepin, tubercidin and AZT. Defects in SLC29A3 can cause histiocytosis-lymphadenopathy plus syndrome (HLAS; MIM:602782), an autosomal recessive disorder characterised by combined features from 2 or more of four histiocytic disorders (Morgan et al. 2010, Colmenero et al. 2012, Young et al. 2013).
