LY75 and pachyonychia congenita: With respect to LY75 and RNF144A, althogh both proteins were detected in PC tissues based on information presented in “Human Protein Atlas” (https://www.proteinatlas.org/ accessed on 19 December 2020), there are no articles listed in PubMed under the search term “LY75 and prostate cancer” and “RNF144A and prostate cancer” as of 23 January 2021; their involvement in PC thus remains unclear.
