3 families segregating the same missense variant (Gly41Arg) with isolated renal magnesium loss. The 3 families shared the same haplotype, suggesting the families are related by a common ancestor. Functional assays demonstrate that Gly41Arg could act through a dominant negative mechanism. Furthermore, 2 individuals with FXYD2 haploinsufficiency (11q23.3-ter deletion) had normal serum magnesium levels. Null mouse model has a pancreatic phenotype rather than a renal phenotype.
