what type of inheritance is associated with sickle cell anemia
Sickle-cell disease Sickle-cell disease (SCD) is a group of blood disorders typically inherited from a person's parents.[2] The most common type is known as sickle-cell anaemia (SCA).[2] It results in an abnormality in the oxygen-carrying protein haemoglobin (haemoglobin S) found in red blood cells.[2] This leads to a rigid, sickle-like shape under certain circumstances.[2] Problems in sickle cell disease typically begin around 5 to 6 months of age.[1] A number of health problems may develop, such as attacks of pain ("sickle-cell crisis"), anemia, swelling in the hands and feet, bacterial infections, and stroke.[1] Long term pain may develop as people get older.[2] The average life expectancy in the developed world is 40 to 60 years.[2]
