Study Notes
Albinism
- Causes a lack of pigmentation in the skin, hair, and eyes due to a lack of melanin production
- Characterized by a complete or partial absence of melanin production in the body
Sickle Cell Anemia
- Results in a complete or partial absence of pigment in the skin, hair, and eyes
- Characterized by a structural abnormality of red blood cells, specifically a sickle shape
- Primary genetic cause is a mutation in the HBB gene
- Inheritance pattern is autosomal recessive
- Abnormal shape of red blood cells can lead to health complications such as
- Blood clots
- Infections
- Organ failure
- Stroke
- Increased risk of infections
- Jaundice
- Fatigue
- Pain episodes
- Delayed growth and development
- Vision problems
- Increased risk of gallstones
- Increased risk of pulmonary hypertension
Test your knowledge about the genetic condition characterized by a lack of melanin production in the body. Identify the term used to describe the absence of pigment in the skin, hair, and eyes, and learn more about the genetic disorder related to albinism.
