Additionally, in a recent study by Li et al on polycystic kidney disease (PKD), HNF1B was shown to have been regulated by p53S, a mutant version of the tumour suppressor p53. 82RNA‐seq analysis to understand PKD in p53 mutant mice, revealed the suppression of PKD1, PKD2, Pkhd1 (polyductin) and HNF1B expression. This evidence concerns the gene HNF1B and polycystic kidney disease.
