Li-Fraumeni syndrome (LFS) is a cancer predisposition syndrome associated with high risks for a diverse spectrum of childhood- and adult-onset malignancies. The lifetime risk of cancer in individuals with LFS is =70% for men and =90% for women. Five cancer types account for the majority of LFS tumors: adrenocortical carcinomas, breast cancer, central nervous system tumors, osteosarcomas, and soft-tissue sarcomas. LFS is associated with an increased risk of several additional cancers including leukemia, lymphoma, gastrointestinal cancers, cancers of head and neck, kidney, larynx, lung, skin (e.g., melanoma), ovary, pancreas, prostate, testis, and thyroid. Individuals with LFS are at increased risk for cancer in childhood and young adulthood; survivors are at increased risk for multiple primary cancers. [from GeneReviews]

BAP1 tumor predisposition syndrome (BAP1-TPDS) is associated with an increased risk for a specific skin lesion, BAP1-inactivated melanocytic tumors (BIMT; formerly called atypical Spitz tumors), and the following cancers, in descending order of frequency: uveal (eye) melanoma (UM), malignant mesothelioma (MMe), cutaneous melanoma (CM), renal cell carcinoma (RCC), and basal cell carcinoma (BCC). Hepatocellular carcinoma, cholangiocarcinoma, and meningioma may also be associated with BAP1-TPDS. Affected individuals can have more than one type of primary cancer. In general, the median age of onset of these tumors is younger than in the general population. UM tends to be a more aggressive class 2 tumor with higher risk for metastasis and reduced survival compared to UM occurring in the general population. Due to the limited number of families reported to date, the penetrance, natural history, and frequencies of BAP1-associated tumors are yet to be determined. Other suspected but unconfirmed tumors in BAP1-TPDS include (in alphabetic order): breast cancer, neuroendocrine carcinoma, non-small-cell lung adenocarcinoma, thyroid cancer, and urinary bladder cancer. [from GeneReviews]

Fanconi renotubular syndrome-5 (FRTS5) is a mitochondrial disorder characterized by proximal renotubular dysfunction from birth, followed by progressive kidney disease and pulmonary fibrosis. It occurs only in individuals of Acadian descent (Crocker et al., 1997 and Hartmannova et al., 2016). For a discussion of genetic heterogeneity of Fanconi renotubular syndrome, see FRTS1 (134600). [from OMIM]

A carcinoma that arises from the lung and is characterized by the presence of malignant glandular epithelial cells. There is a male predilection with a male to female ratio of 2:1. Usually lung adenocarcinoma is asymptomatic and is identified through screening studies or as an incidental radiologic finding. If clinical symptoms are present they include shortness of breath, cough, hemoptysis, chest pain, and fever. Tobacco smoke is a known risk factor. [from NCI]
