Project name: Homo sapiens

Description: The genetic cause for PPB in association with renal tumor and small bowel polyps remains to be identified. Activation of components of the mTOR signalling pathway in the disease lesions suggests that this signal transduction route may be involved in disease pathogenesis and that rapamycin, an inhibitor of mTOR, might be effective in the treatment of PPB and associated lesions.Overall design: A combination of molecular cytogenetics and gene-specific mutation screens were performed to search for an underlying genetic cause for PPB in association with small bowel polyps. Immunohistochemical analysis to measure mTOR activation was performed on tissue from renal and lung tumor and small bowel polyps from the index case
