SLC12A3 and Wilson disease: Smolinski et al. [36] found that NCC concentration was negatively correlated with WD severity, based on both UWDRS part II and UWDRS part III (r = −0.295, p < 0.05 and r = −0.315, p < 0.05, respectively; age- and sex-adjusted r = −0.318, p < 0.05 and r = −0.382, p < 0.05, respectively).
