Furthermore, Lys264Arg mutation in ataxin-7 is among several common non-synonymous SNPs associated with breast cancer susceptibility [327], and a fusion between ataxin-7 and DNA repair protein Rad51C is expressed in colorectal tumors [328], whereas spleen-specific isoform of ataxin-7 was suggested to serve as a potential marker of the lymphoma-affected spleen [329]. This evidence concerns the gene ATXN7 and colorectal neoplasm.
