What is Gene Testing: Gene tests examine your DNA to identify specific changes (mutations) that can increase your risk of developing or causing genetic conditions. These tests can focus on a single gene, multiple genes, or your entire DNA makeup, which is called genomic testing. A gene test analyzes your DNA to identify changes (mutations) in your genes. These changes can affect your health in various ways, including increasing your risk of developing certain diseases, influencing your response to medications, and determining your susceptibility to environmental factors. Types of Gene Tests: Diagnostic gene tests: Confirm or rule out a suspected genetic condition. Predictive gene tests: Estimate the likelihood of developing a genetic disease in the future. Carrier gene tests: Determine if you carry a gene for a genetic condition that you may pass on to your children. Pharmacogenetic tests: Identify how your genes may affect your response to medications. Prenatal gene tests: Detect genetic abnormalities in a fetus. Importance of Gene Testing: Early detection: Can help identify diseases early when treatment is most effective. Personalized medicine: Allows for tailored treatment plans based on individual genetic makeup. Family planning: Helps couples understand their risk of passing on genetic conditions to their children. Chromosome Testing A chromosome test analyzes the number and structure of chromosomes in a person's cells. Chromosomes are thread-like structures found in the nucleus of every cell. They contain DNA, the genetic material that determines inherited traits. Why is it done? To detect chromosomal abnormalities: These can lead to genetic disorders like Down syndrome, Turner syndrome, or Klinefelter syndrome. To diagnose birth defects: Certain birth defects are associated with chromosomal changes. To determine the sex of a fetus: By examining the sex chromosomes (X and Y). To investigate infertility issues: Sometimes, chromosomal abnormalities can affect fertility. DNA test can lead to detect genetic disorders like Down syndrome, Turner syndrome, or Klinefelter syndrome, Huntington's disease,Cystic fibrosis,Sickle cell disease,Phenylketonuria,Colon (colorectal) cancer,Breast cancer.
