The 10 Most Common Genetic Disorders

Understanding Marfan Syndrome

Marfan syndrome, first documented in 1896, is a genetic disorder that primarily affects the connective tissue. This condition is characterized by various external manifestations, including disproportionately long limbs, slender fingers, and excessive growth. In addition to these physical symptoms, Marfan syndrome also involves cardiovascular malformations, such as structural abnormalities in the aorta and damage to the heart valves. Moreover, this disorder can impact other systems in the body, such as the eyes, lungs, skeletal system, and circulatory system.

Marfan syndrome can be inherited from a single parent, as it is a genetic condition. Another possible cause of the disease is gene mutation resulting from an accumulation of excessive growth hormone. This can lead to the rapid development of the lungs and subsequent weakening of the aorta, ultimately contributing to the development of Marfan syndrome.


Understanding Hereditary Spherocytosis

Hereditary spherocytosis is a genetic condition characterized by the transformation of normally disc-shaped red blood cells into spherical shapes. This abnormal shape causes the red blood cells to become rigid and more prone to being captured, enlarged, and destroyed by the spleen, resulting in anemia. While anemia is typically mild in most cases, it can escalate into a more severe form if an infection occurs. Severe cases of hereditary spherocytosis may also lead to the development of jaundice or gallstones. In some instances, young adults with this disorder may even experience symptoms similar to those of hepatitis. Additionally, individuals with hereditary spherocytosis may exhibit bone abnormalities, such as a tower-shaped skull or extra fingers and toes. While treatment is generally unnecessary, severe anemia may require surgical intervention, such as the removal of the spleen.
