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.

Radiotherapy for Langerhans Cell Histiocytosis of Bilateral Eyelids.

Langerhans cell histiocytosis (LCH) is a rare disorder with numerous clinicopathological variants with differing clinical courses, treatment methods, and prognoses. We report one patient with atypical LCH of the bilateral lower eyelids and subsequent successful treatment with local radiation therapy.
