Figures & data

Figure 1. Clinical phenotypes and molecular genetics of renal ciliopathies.

Note:Variability in the age of onset of KF and the median age of onset of clinical symptoms are shown as extended diamond bars. ADPKD mostly presents in adulthood (30-40 years of age) although a small proportion of cases reported in early life (1-10 years of age) due to biallelic or digenic or severe loss of function PKD1/PKD2 variants. The age of presentation for ARPKD varies with approximately one third of patients presenting before 1 year of age, one third between 1 and 20 years of age and one third after 20 years with mutations in PKHD1 being the most common cause. In juvenile NPHP, KF develops at a median age of 13 years whereas in adult form, which is clinically and histologically similar to the juvenile NPHP, KF develops after 15-20 years of age. Infantile NPHP is rare with KF appearing during first year of life. The current clinical trials with name of the drug, ClinicalTrials.gov identifier number and the age range of patients the study is recruiting is shown for ADPKD and ARPKD. There are currently no clinical trials in progress for NPHP. (Created using BioRender.com).
