NPHP-related polycystic kidney disease in man and mice
Zusammenfassung der Projektergebnisse
Genetic heterogeneity and phenotypic variability are major challenges in familial nephronophthisis and related ciliopathies. To date, mutations in 20 different genes (NPHP1 to -20) have been identified causing either isolated kidney disease or complex multiorgan disorders. At the beginning of the project, only 8 NPHP genes were described to cause Nephropnothisis and related ciliopathies and knowledge about phenotypic variability was limited. Our aim was to increase this knowledge and to further characterize causes and pathogenic mechanisms of NPHP-related polycystic kidney disease in man and mice. Our work helped to identify and functionally characterize novel genes causing Nephronopthisis and related ciliopathies. At the same time, our findings increased the knowledge about NPHP proteins which not only function at the ciliary transition zone, but can also be involved in DNA damage repair. By combining proteomics, genetics and cell biology we defined a ciliary landscape proteins, interactions and complexes which represents a useful resource for Systems Medicine not only in cystic kidney disease research. One important part was the implementation of the NPHP Registry (www.nephreg.de). This registry currently harbours 152 patients and has been utilized to implement interactive online case reporting, communication and education tools. This registry and mouse studies enabled us to analyze the genetic heterogeneity and phenotypic variability (genotype/phenotype correlation) in familial nephronophthisis and related ciliopathies which still is a major challenge. Research continues within the NEOCYST project (Network for early onset cystic kidney disease), financed by the Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung, BMBF) and supported by the German Society of pediatric nephrology (GPN). NEOCYST, coordinated by my team in Münster, is a multicenter, interdisciplinary network of clinicians and scientists exploring early onset cystic kidney diseases. The goals of NEOCYST are to increase the knowledge on the epidemiology, the phenotypical spectrum, the underlying genetic and pathophysiological mechanisms as well as the individual prognosis of early onset cystic kidney diseases and thereby to improve the clinical management and counselling of affected patients.
