What is genomics?

The study of genome is called genomics. Human genome is an instruction manual which helps every single physiological process and the growth of the human body. Your genome is unique to you. The knowledge of your genome will help you make better lifestyle choices and informed decisions about your health.

Is it true that you can do nothing, if you have a genetic mutation, as you will anyway get the disease?

No, genetic health is constantly influenced by our diet and lifestyle. If you are eating right, there is a chance that the bad genes may not express.

Are mutations always bad?

– Mutations are just changes in the regular DNA. Sometimes it can cause disease and sometimes it helps in better adaptation to a particular environment.

What does it mean if I have bowel cancer gene, will I get cancer?

No, It means you are at higher risk compared to other people. So, you need to watch your diet more carefully, get regular screening, to avoid getting it.

Do males get breast cancer, if they are genetically at risk?

If males have breast cancer genes, their close female relatives need to evaluate for the breast cancer risk. Males can get breast cancer, however it is rare.

Nothing runs in family, so do I have a perfect genome?

Diseases due to mutations can sometimes skip generations. This is because gene expression can depend on multiple complex factors. Gene profiling can help you know the risks, if any.

If there is heart disease risk in family, does that mean they are not prone to other conditions like cancer?

Unless gene profiling is done, we cannot say if you are at risk of cancer risk or not. Having one prominent disease condition in a family does not imply other risks are absent.

If I have a genetic condition, does that mean something bad happened in the family tree or my parents did something wrong?

Genetic condition due to certain mutations can happen several ways. It can be due to a change which happened in the family tree and got passed on. It can also be a de novo mutation, which happened only in one individual during the embryo development.

Does one gene determine one characteristic like eye color or skin color?

Usually physical characteristics are determined by a set of genes, not just one. However, there can be certain functions in the body, which require one major gene to be expressed.

Are changes in DNA rare?

No, our DNA is constantly evolving. Changes happen every day. However, only some changes are prominent to show immediate effect. Most of the genetic mutations usually take several generations to start showing effects.
