Genetic disorders are interesting but can also be complicated. These disorders happen mainly because of problems in our genes or chromosomes. Let’s look at some common ones:
Cystic Fibrosis: This disorder happens from a change in the CFTR gene. It causes the body to produce thick, sticky mucus. This can hurt the lungs and make it hard for the digestive system to work properly.
Down Syndrome: Most people have 46 chromosomes, but people with Down syndrome have one extra copy of chromosome 21. This is called trisomy 21. It can cause delays in development and changes in how someone looks.
Sickle Cell Anemia: This disorder is caused by a change in the HBB gene. It makes red blood cells stiff and shaped like a sickle (which looks a bit like a curved knife). This can block blood flow and can lead to pain and tiredness.
Hemophilia: This happens when genes that help our blood clot don’t work right. Because of this, people with hemophilia can have trouble stopping bleeding when they get hurt.
Learning about these disorders shows us how important genetics is to our health. It’s amazing to think that just one little change in our DNA can make such a big difference!
