The Human Genome & Disease ascociated genes

HUMAN GENOME: The genome of an organism is the entire genetic material of that organism. The human genome has great importance in medicine. It enables us to: - search for genes linked to different types of disease - understand inherited disorders and their treatment - trace human migration patterns from the past DISEASE ASCOCIATED GENES: - Scientists are searching for disease associated genes. One example was those that can contribute to breast cancer, which are known as BRCA1 and BRCA2. - Mutations in these genes account for approximately 10% of all inherited breast cancer cases detected. Scientists studied families where it was known to be inherited and were able to create a pedigree analysis, which is similar to a family tree diagram that showed the close relationship of those affected and unaffected within the family, differences in DNA can be analysed. - It is now possible to detect the presence of the genes by having a simple blood test
