Nephronophthisis-related ciliopathies(NPHP-RC)represent one of the most common causes of chronic kidney disease in the first three decades of life and are characterized by a broad genetic and clinical heterogeneity.1 To date,more than 90 genes have been identified that cause autosomalrecessive NPHP-RC if mutated,accounting for up to 60%of cases.1 Among these,homozygous deletions of NPHP1 are the most common *** genes localize to primary cilia,basal bodies,or the centrosome and lead to a primary ciliary disruption if mutated,thereby causing a broad phenotypical spectrum.1 Patients that suffer from NPHP-RC can either have an isolated renal phenotype,such as polyuria,polydipsia,decreased urinary concentration ability,and secondary enuresis due to loss of tubular function,or present with extrarenal symptoms including retinal degeneration,cerebellar vermis hypoplasia,or hepatic *** are often diagnosed in early adolescence,reaching end-stage renal disease before 25 years of age,but early onset and rapidly progressive forms of NPHP-RC also exist.1 Renal ultrasound indicates kidneys of normal or reduced renal length with increased echogenicity and corticomedullary cysts.
