What is the Difference Between Sickle Cell SS and SC?

🆚 Go to Comparative Table 🆚

Sickle Cell Anemia (SS) and Sickle Hemoglobin-C Disease (SC) are both forms of sickle cell disease, a group of inherited blood disorders that affect the hemoglobin in red blood cells, causing them to become sickle-shaped and lead to various complications. The main differences between Sickle Cell SS and SC are:

  1. Inheritance: Sickle Cell Anemia (SS) occurs when a child inherits one sickle cell gene from each parent, while Sickle Hemoglobin-C Disease (SC) involves a slightly different substitution in the hemoglobin gene.
  2. Symptoms: Both SC and SS can cause similar symptoms, such as painful crisis episodes, anemia, and organ damage. However, SC may cause less severe anemia compared to SS.
  3. Frequency: Sickle Cell Anemia is more common in populations of African and Indian descent, while Sickle Hemoglobin-C Disease is more prevalent in West African, Mediterranean, and Middle Eastern populations.

Both conditions can lead to lifelong debilitation, poor quality of life, and early mortality due to chronic anemia and organ damage. Treatment and management of these conditions may vary depending on the severity of symptoms and the specific complications experienced by the individual.

Comparative Table: Sickle Cell SS vs SC

Sickle cell SS (Hb SS) and sickle cell SC (Hb SC) are two different types of sickle cell disease, a genetic condition that affects the shape of red blood cells. Here is a table highlighting the differences between the two:

Feature Sickle Cell SS (Hb SS) Sickle Cell SC (Hb SC)
Genotype Inheritance of two sickle hemoglobin S genes (one from each parent) Inheritance of one sickle hemoglobin S gene and one normal hemoglobin A gene (one from each parent)
Anemia Severity More severe anemia, with higher markers of hemolysis and lower hemoglobin values Less severe anemia
Prevalence Most common type of sickle cell disease, affecting one out of every 400-600 black Americans Less common than Hb SS, affecting about one out of every 1,000 black Americans
Complications Increased risk of cardiopulmonary complications Damage to hip joints and the retina are more common, but less severe than Hb SS

Both diseases carry similar symptoms, but the severity of anemia and complications varies between the two types. Hb SS is considered the more severe form of sickle cell disease, while Hb SC is thought to be milder.
