In contrast to genetic testing, which focuses on a single gene or group of genes, genomic testing examines all of a person’s genes. Genomic testing, a more recent branch of genetics, is the act of looking at an organism’s whole genome (the genes that make up an organism), such as the human body. Approximately 3 billion DNA units make up each of the 25,000 distinct genes that exist in each individual.

Doctors are often able to suggest specific treatments and chemotherapies that specifically target a patient’s particular kind of cancer thanks to genomic testing, whether performed on cancer cells or through a blood sample. This targeting can help lessen negative effects and stop medication from harming healthy cells.
It is advised that you consult your oncologist if you have cancer to find out if you qualify for genomic or other forms of genetic testing. If an inherited mutation is discovered, a medical specialist known as a genetic counselor can assist you and your family in understanding the implications of the discovery and assist in setting up additional testing within the family so those who have inherited genetic risk can access proactive screening and risk-reducing measures.

Finally, we examine how the availability of online DNA testing, the growing use of genomic testing for people who are unable to assent, and the possibility of re-interrogating previously collected genetic data might challenge established models of informed consent. The term “genomics” is used in this review to refer to both genetics (specific genes) and genomics (all genes in a genome). For more details visit: https://gotoknowtest.com/news-insights/
