{Reference Type}: Case Reports {Title}: A female patient with Dent disease due to skewed X-chromosome inactivation. {Author}: D'Ambrosio V;Wan ER;Siew K;Hayes W;Walsh SB; {Journal}: Clin Kidney J {Volume}: 17 {Issue}: 6 {Year}: 2024 Jun {Factor}: 5.86 {DOI}: 10.1093/ckj/sfae092 {Abstract}: X-linked proximal tubulopathies are rare diseases that predominantly affect men. Women are generally carriers and clinical or biochemical manifestations are usually absent or mild. We present the case of a young woman who presented with a full phenotype of Dent disease type 1 due to a de novo mutation in the CLCN5 gene and a skewed X-chromosome inactivation. Although cases of overt Dent disease type 2 and Lowe syndrome in women have been described in the literature, to our knowledge this is the first case of overt Dent disease type 1.
