Other SLCs with increased expression in humans in association with HD were divalent metal transporter 1 (DMT1, SLC11A2; although not statistically significant) [154], equilibrative nucleoside transporter 1 (ENT1, SLC29A1) [155], monocarboxylate transporter 9 (MCT9, SLC16A9) [142], prostein (SLC45A3) [156], and urea transporter 1 (UT1, SLC14A1) [142]. This evidence concerns the gene SLC45A3 and Huntington disease.
