Study Notes
Chromosomal Abnormalities
- Alpha-1 Antitrypsin deficiency is a genetic disorder caused by a mutation on chromosome 14, leading to enzyme deficiency, cirrhosis of the liver, and emphysema, typically manifesting in middle age.
Hematological Disorders
- Alpha Thalassemia is a severe anemia caused by a mutation on chromosome 16, reducing the blood's ability to carry oxygen, resulting in stillbirth or death soon after birth in almost all affected infants.
- Beta Thalassemia (Cooley's anemia) is a severe anemia caused by a mutation on chromosome 11, leading to weakness, fatigue, and frequent illness, typically resulting in death in adolescence or young adulthood.
- Sickle cell Anemia is a genetic disorder characterized by deformed, fragile red blood cells that can clog blood vessels, depriving the body of oxygen, with symptoms including severe pain, stunted growth, frequent infections, leg ulcers, gallstones, susceptibility to pneumonia, and stroke.
Neurological Disorders
- Anencephaly is a condition where brain tissues are absent, resulting in stillbirth or death soon after birth.
- Tay-Sachs Disease is a degenerative disease of the brain and nerve cells, caused by a mutation, resulting in death before age 5.
- Spina Bifida is a condition where the spinal canal is incompletely closed, resulting in muscle weakness or paralysis, loss of bladder and bowel control, and often accompanied by hydrocephalus, leading to mental retardation.
Metabolic Disorders
- Phenylketonuria (PKU) is a metabolic disorder caused by a mutation, resulting in mental retardation.
Pulmonary and Renal Disorders
- Cystic Fibrosis is a genetic disorder caused by a mutation on chromosome 7, characterized by overproduction of mucus, which collects in the lung and digestive tract, resulting in stunted growth and usually death before age 30.
- Polycystic Kidney disease has an infantile form, leading to enlarged kidneys, respiratory problems, and congestive heart failure, while the adult form is characterized by kidney pain, kidney stones, and hypertension, resulting in chronic kidney failure.
Muscular Disorders
- Duchenne Muscular Dystrophy is a fatal disease usually found in males, caused by a mutation on the X sex chromosome, marked by muscle weakness and minor mental retardation, resulting in respiratory failure and death usually in young adulthood.
- Hemophilia is a genetic disorder caused by a mutation on the X sex chromosome, characterized by excessive bleeding, usually affecting males, and can lead to crippling arthritis in adulthood.
