NF2 is also mutated and deleted in mesotheliomas (Sekido et al., 1995), clear cell renal cell carcinomas (Dalgliesh et al., 2010), collecting duct carcinomas of the kidney (Pal et al., 2016), and renal cell carcinomas with sarcomatoid dedifferentiation (Malouf et al., 2016). This evidence concerns the gene NF2 and collecting duct carcinoma.
