Is it true that autosomal Dominant Polycystic Kidney Disease is caused by mutations in the PKD1 or PKD2 genes?
Yes. Autosomal Dominant Polycystic Kidney Disease (ADPKD) is primarily caused by mutations in the PKD1 or PKD2 genes, which lead to the functional deficiency of polycystin proteins and subsequent cyst formation in the kidneys.
Verdict: SUPPORTED · 10 sources for, 0 against · Last checked
The analysis
All retrieved papers that discuss the genetic etiology of ADPKD consistently attribute the disorder to mutations in either the PKD1 or PKD2 genes, providing overwhelming support for the claim.
Evidence for · 10
The study identifies pathogenic mutations in either the PKD1 or PKD2 genes as the underlying genetic cause in ADPKD patients.
