What is Genetic testing?

Genetic testing, Genomic Testing, is a test to examine a person’s risk of developing hereditary disease or to tailor personalized medication.

The process of analyzing the DNA of cells or tissues to look for genetic changes that may be a sign of a disease such as cancer.

For example, testing mutations in the BRCA gene for early detection or preventing the development of breast cancer.

What is Gene? What is Genome?

Gene is a fragment in the DNA strand that encodes physiological features, for example, eye color.

The genes genes are inherited upon cell division when the DNA molecule replicates, and each new cell receives a copy of the replicated DNA.

Genome is the full system of all the genes in an organism.

In humans, all genes are located on structures called chromosomes. Chromosomes are complexes of DNA and proteins bind to each other.

Almost every cell in the body contains a complete copy of the genome. The genome contains all the information a person needs for development and growth.

The Genome study provides an understanding of how cancer cells are formed and respond to therapy.

People with different genetic will respond differently to a particular drug.

For example, So certain drugs that are not given to people with certain DNA mutations.

What is a Mutation?

Mutation is a change of the DNA sequence in the cell.

Mutations can be caused by errors during cell division, or they can be caused by exposure to substances harmful to DNA (free radicals, asbestos, etc.).

Mutations can be harmful, beneficial, or have no effect.

When they appear in egg or sperm cells, they can be inherited.

Sometimes cancer is seen in families more often than was randomly expected (coincidence). This cancer often occurs at a young age, and may indicate the presence of a genetic mutation that increases the risk of cancer. It also constitutes a sign of environmental factors affecting life in a common environment.

If mutations occur in other types of cells, they are not inherited and are called somatic mutations.

Mutations can lead to cancer or other diseases

When is it important to perform genetic testing?

Why it is important to do genetic testing?

In cancer, personalized medicine uses the patient’s specific disease characteristics and medical background to form a personalized therapy program.
