Associated Diseases (KEGG IDs)Childhood cancer retinoblastoma (RB) [MIM:180200]: Congenital malignant tumor that arises from the nuclear layers of the retina. It occurs in about 1:20'000 live births and represents about 2% of childhood malignancies. It is bilateral in about 30% of cases. Although most RB appear sporadically, about 20% are transmitted as an autosomal dominant trait with incomplete penetrance. The diagnosis is usually made before the age of 2 years when strabismus or a gray to yellow reflex from pupil ('cat eye') is investigated. {ECO:0000269|PubMed:10671068, ECO:0000269|PubMed:11524739, ECO:0000269|PubMed:1352883, ECO:0000269|PubMed:2594029, ECO:0000269|PubMed:7704558, ECO:0000269|PubMed:7795591, ECO:0000269|PubMed:7927327, ECO:0000269|PubMed:8346255, ECO:0000269|PubMed:8605116, ECO:0000269|PubMed:8776589, ECO:0000269|PubMed:9140452, ECO:0000269|PubMed:9311732, ECO:0000269|PubMed:9973307}. The disease is caused by mutations affecting the gene represented in this entry.; Bladder cancer (BLC) [MIM:109800]: A malignancy originating in tissues of the urinary bladder. It often presents with multiple tumors appearing at different times and at different sites in the bladder. Most bladder cancers are transitional cell carcinomas that begin in cells that normally make up the inner lining of the bladder. Other types of bladder cancer include squamous cell carcinoma (cancer that begins in thin, flat cells) and adenocarcinoma (cancer that begins in cells that make and release mucus and other fluids). Bladder cancer is a complex disorder with both genetic and environmental influences. Disease susceptibility is associated with variations affecting the gene represented in this entry.; Osteogenic sarcoma (OSRC) [MIM:259500]: A sarcoma originating in bone-forming cells, affecting the ends of long bones. The disease is caused by mutations affecting the gene represented in this entry.
General Description of Retinoblastoma Gene Protein .
This antibody recognizes human retinoblastoma gene protein. Rb gene, a prototype of tumor suppressor genes, has been associated with development and/or progression of bladder cancer as well as sarcoma and small cell lung cancer. Functional Rb gene loss has been reported to occur in bladder cancer and osteosarcoma. A significantly poorer tumor-free survival rate was noted for those patients who had a tumor with an altered Rb protein with or without vascular invasion.

Retinoblastoma Gene Protein Information for Pathologists

Summary:

Retinoblastoma Gene Product (Rb) is a 110-114 kDa nuclear protein that plays a crucial role in cell cycle progression by regulating cell cycle arrest at G1-S. It is encoded by a tumor suppressor gene at 13q14. Rb is present in germline mutations or loss predispose to retinoblastoma and osteosarcoma. Somatic mutations cause various tumors and specific point mutations my inhibit Rb-1 and c-myc binding. For thyroid neoplasms, follicular adenomas were usually positive, follicular and papillary carcinomas were usually negative.
