Study Notes
Genetic Disorders
- Genetic disorders are health problems caused by defects in one or more genes or chromosomes.
- Defects can arise during cell division or from mutagens.
- Examples include sickle-cell anemia, cystic fibrosis, color blindness, and Down syndrome.
Sickle-Cell Anemia
- A genetic disorder where red blood cells become sickle-shaped.
Cystic Fibrosis
- Characterized by the body producing thick, sticky mucus.
- This mucus interferes with breathing and nutrient absorption.
Color Blindness
- Difficulty distinguishing between certain colours (red/green, blue/yellow) or seeing only black, white, and gray.
Down Syndrome
- Caused by an extra copy of chromosome 21.
- Symptoms include delayed mental and social development, flattened facial features, and slanted eyes.
Diagnostic Procedures
- Amniocentesis: A medical procedure where amniotic fluid is removed for genetic disorder analysis.
- Chorionic villus sampling: A procedure that involves taking a sample of the placenta for genetic disorder testing.
Genetic Counseling
- Genetic counselors help parents understand the risk of having a child with a genetic disorder.
