When we explore human genetics, it’s really interesting to see the different inherited disorders that can happen. These disorders usually come from problems in our chromosomes or specific gene changes, and some are more common than others. Let’s check out a few of the most common inherited disorders:
Cystic Fibrosis: This condition affects the lungs, digestion, and reproduction because of a change in the CFTR gene. It causes thick and sticky mucus to build up, making it hard to breathe and digest food. Cystic fibrosis is called an autosomal recessive disorder, which means a person needs to have two copies of the faulty gene to be impacted.
Sickle Cell Disease: This disorder is caused by a change in the HBB gene. It also falls under the autosomal recessive category. It makes the red blood cells look like sickles, which can block blood flow and lead to painful episodes known as crises.
Hemophilia: Hemophilia is an example of an X-linked recessive disorder. It affects how well blood can clot. This means people can bleed a lot from small injuries. It mostly affects boys who inherit the faulty gene from their mothers, who are usually just carriers.
Down Syndrome: This well-known disorder happens when there’s an extra copy of chromosome 21, making a total of three copies (this is called trisomy 21). People with Down syndrome often have unique physical traits and different levels of learning challenges.
Huntington's Disease: This is an autosomal dominant disorder caused by a change in the HTT gene. Unlike the others, you only need one faulty gene to be affected. It leads to problems with movement and mental health that usually get worse over time.
Learning about these disorders is really important for genetic counseling. This is especially true for families who might be affected or at risk. Genetic counselors can help people make smart decisions about testing, managing risks, and planning for their families. This knowledge not only helps individuals but also improves the quality of life and future for those with inherited disorders.
