Novel germline c-MET mutation in a family with hereditary papillary renal carcinoma.
Summary of "Novel germline c-MET mutation in a family with hereditary papillary renal carcinoma."
Hereditary papillary renal carcinoma (HPRC) is a highly penetrant hereditary renal cancer syndrome caused by germline missense mutations in the c-MET proto-oncogene. HPRC is clinically characterized by multiple bilateral papillary renal-cell carcinomas. Here we report a family with a novel missense mutation in c-MET. The original pathology report of four primary kidney cancers (1988-1997) revealed renal-cell carcinoma. A revised report described multiple adenomas and papillary renal-cell carcinomas with focal clear cells and a mixture of type 1 and type 2 pattern, emphasizing the importance of revised pathology examinations in possible hereditary renal-cell carcinomas especially when described before 1997.

Medical and Biotech [MESH] Definitions
Carcinoma, Renal Cell
A heterogeneous group of sporadic or hereditary carcinoma derived from cells of the KIDNEYS. There are several subtypes including the clear cells, the papillary, the chromophobe, the collecting duct, the spindle cells (sarcomatoid), or mixed cell-type carcinoma.
Colorectal Neoplasms, Hereditary Nonpolyposis
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Medullary Sponge Kidney
A non-hereditary KIDNEY disorder characterized by the abnormally dilated (ECTASIA) medullary and inner papillary portions of the collecting ducts. These collecting ducts usually contain CYSTS or DIVERTICULA filled with jelly-like material or small calculi (KIDNEY STONES) leading to infections or obstruction. It should be distinguished from congenital or hereditary POLYCYSTIC KIDNEY DISEASES.
Carcinoma, Papillary, Follicular
A thyroid neoplasm of mixed papillary and follicular arrangement. Its biological behavior and prognosis is the same as that of a papillary adenocarcinoma of the thyroid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1271)
Nephritis, Hereditary
A group of inherited conditions characterized initially by HEMATURIA and slowly progressing to RENAL INSUFFICIENCY. The most common form is the Alport syndrome (hereditary nephritis with HEARING LOSS) which is caused by mutations in genes for TYPE IV COLLAGEN and defective GLOMERULAR BASEMENT MEMBRANE.
