Ann Surg Oncol. 2017;24:2206-2212 pubmed publisher..Determining the grade in both the primary tumor and a metastasis is important for estimating prognosis and to help inform decisions regarding additional therapies. ..
- Howe J, Roth S, Ringold J, Summers R, Järvinen H, Sistonen P, et al. Mutations in the SMAD4/DPC4 gene in juvenile polyposis. Science. 1998;280:1086-8 pubmed..The mutant SMAD4 proteins are predicted to be truncated at the carboxyl-terminus and lack sequences required for normal function. These results confirm an important role for SMAD4 in the development of gastrointestinal tumors. ..

Nat Genet. 2001;28:184-7 pubmed..These findings indicate involvement of an additional gene in the transforming growth factor-beta (TGF-beta) superfamily in the genesis of JP, and document an unanticipated function for BMP in colonic epithelial growth control. ..

J Med Genet. 2004;41:484-91 pubmed..Since mutations were not found in more than half the JP patients, either additional genes predisposing to JP remain to be discovered, or alternate means of inactivation of the two known genes are responsible for these JP cases. ..

Cancer Genet Cytogenet. 2008;181:52-4 pubmed publisher..This mutation caused protein truncation, and represents a novel case of consecutive nonsense mutations in human disease. ..

We conclude that GIPR could provide an improved signal-to-noise ratio for imaging versus SSTR2 and represents a promising novel therapeutic target in GDNETs. ..
