Exome sequencing as a diagnostic tool in chronic kidney disease: ready for clinical application?

Purpose of review Patients who develop chronic kidney disease at an early age, or from an uncertain cause, may benefit from genomic sequencing approaches to define causative mutations and inform subsequent management. Recent findings Whole-exome sequencing has been used to investigate the molecular genetic variants associated with chronic kidney disease in both specific phenotypes such as steroid-resistant nephrotic syndrome, and in large cohorts of patients not selected for a certain diagnosis. These studies have shown that whole-exome sequencing is able to find a genetic variant in a significant number of patients. Often these variants may reclassify the diagnosis, the variants may have ramifications for the patient's management, and some variants may be previously undescribed in the literature. Summary Whole-exome sequencing is likely to become widely used in the investigation of chronic kidney disease, especially in certain phenotypes.
