A rat showing hereditary renal cell carcinoma was found in a Jcl:SD rat colony and named Nihon rat. In this rat strain mutation was identified as an insertion of a cytosine (C) in a C tract within exon 3 of Flcn . This germline mutation results in a frameshift and produces a stop codon 26 amino-acids downstream. Thereafter they have been maintained at Dainippon Sumitomo Pharma Co., Ltd.
