Nephronophthisis related to homozygous NPHP1 gene deletion as a cause of chronic renal failure in adults

Abstract
Nephronophthisis (NPH) is an autosomal recessive nephropathy with chronic tubulointerstitial involvement, which represents the leading cause of end-stage renal disease (ESRD) in children and adolescents. According to the age at onset of ESRD, three forms of NPH have been described: infantile, juvenile (the most frequent) and adolescent.
