He is credited with the description of sickle-cell disease and was one of the first physicians to describe the symptoms of myocardial infarction.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to the red blood cells adopting an abnormal ...
The Sickle Cell Disease Association of America, Inc. originated in Racine, Wisconsin. Representatives from 15 different community-based sickle cell organizations came together at Wingspread, a community center, as guest of the Johnson Foundation.

Hematology. Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous). Those who are heterozygous for the sickle cell allele produce both ...
