Genetic Diseases of the Kidney

The number of genes associated with renal disease is increasing every day and this has led to a clearer understanding of the pathophysiology of renal disease in many disorders. It is also appreciated now that a genetic mutation(s) underlie many renal syndromes. Genetic testing may also offer the possibility to diagnose some renal diseases without the need for a renal biopsy. It also allows the prenatal diagnosis of certain renal diseases in at risk fetuses or identification of potential renal disease before it has become manifest. Finally, identification of a specific gene mutation holds the possibility of correction though gene therapy in the future. It is increasingly clear that many renal disorders in pediatrics are a consequence of genetic mutations. In the future, genetic testing will become as easy and as common as ordering a serum creatinine today.
