X-Linked Kidney Disorders in Women

Abstract

A number of genes that cause inherited kidney disorders reside on the X chromosome. Given that males have only a single active X chromosome, these disorders clinically manifest primarily in men and boys. However, phenotypes in female carriers of X-linked kidney conditions are becoming more and more recognized. This article reviews the biology of X inactivation as well as the kidney phenotype in women and girls with a number of X-linked kidney disorders including Alport syndrome, Fabry disease, nephrogenic diabetes insipidus, X-linked hypophosphatemic rickets, Dent disease, and Lowe syndrome.

Keywords: Alport syndrome; Dent disease; Fabry disease; Lowe syndrome; X-inactivation; X-linked hypophosphatemic rickets; nephrogenic diabetes insipidus.
