Medical Genetics Viruses, ultraviolet (Uv) radiation, and chemicals can all damage genes in the human body. If particular genes are affected a person can develop cancer. Understanding how genes cause cancer though, first requires a basic understanding of several genetic terms and concepts

Medical Genetics Tumors are hereditary Hereditary retinoblastoma is an autosomal dominant trait in which susceptibility to retinoblastoma is inherited. This is an unusual dominant trait in that a mutation in one rb gene is not sufficient to cause symptoms, but mutations in the second allele often arise during development

This is an unusual "dominant" trait in that a mutation in one RB gene is not sufficient to cause symptoms, but mutations in the second allele often arise during development

Medical Genetics The mutations occur after birth and result in tumor formation Tumors usually develop in only one eye and patients are not at high risk for other cancers both alleles need to be mutated in a single cell, and that is why this form typically occurs only in one eye

Medical Genetics Chromosome and tumors Detailed studies of the philadelphia chromosome show that most of chromosome 22 has been translocated onto the long arm of chromosome 9. In addition the small distal portion of the short arm of chromosome 9 is translocated to chromosome 22. this translocation, which is found only in tumor cells indicates that a patient has chronic myelogenous leukemia(CML). In CML, the cells that produce blood cells for the body(the hematopoietic cells grow uncontrollably, leading to cancer
