SLC26A6 and nephrolithiasis: Other groups have also found polymorphisms in the SLC26A6 gene in kidney stone cohorts, but the functional significance of the individual polymorphisms for oxalate transport has not been elucidated in the same detail as in the study discussed above, and therefore the functional involvement of these variants in the development of the nephrolithiasis of these patients not certain (Monico et al., 2008; Corbetta et al., 2009; Lu et al., 2016).
