Question

Sequencing the human genome may bring to light a number of genes that are the basis for known genetic diseases or that predispose a person to a condition such as heart disease, cancer, or Alzheimer's disease. Yet finding a gene for an illness may not lead to an immediate cure. Would you want to be tested to learn whether you had a genetic disease or predisposition if no cure was available? Why or why not?

Please help me!!!

Answer 1

The sequencing of whole genome or DNA (deoxyribonucleic acid) of the individual is called DNA typing or genome sequencing. The genome sequencing is helpful in determining the specific treatment suitable for the patient, i.e. the personalized medicine.

Although no specific cure is available to most of the genetic diseases, screening would be helpful because the preventive measures can be implemented to reduce the risk of disease or severity of the disease. For example, people with genetic predisposition to heart diseases can take a healthy diet and regular exercise to delay the disease onset or to reduce the disease severity. This works because both the genetic and environmental factors influence the gene expression.
