It has been shown that there was significant difference in P53 (OMIM: 191170) expression between papillary urothelial neoplasm of low malignant potential (PUNLMP) and papillary low‐grade TCC in which the P53 overexpression was more frequent among papillary low‐grade TCC tumors (Kalantari & Ahmadnia, 2007). Here, TP53 is linked to tarsal-carpal coalition syndrome.
