SUMMARY: Identification of 2 genomic regions associated with risk for severe aplastic anemia.
OVERVIEW: Aplastic anemia is an autoimmune disease in which the bone marrow does not produce enough blood cells. In severe cases aplastic anemia can become life-threatening. This genome-wide association study sought to identify variants associated with risk of severe aplastic anemia by examining genetic information of nearly 3,000 individuals of European descent. The results indicated 2 genetic regions linked to the risk of severe aplastic anemia. Both genetic regions encode for proteins of the human leukocyte antigen (HLA) system that plays a role in the regulation of the immune system.
DID YOU KNOW? Exposure to toxic chemicals like pesticides and insecticides can increase risk of aplastic anemia. The condition can also be a temporary side effect of radiation and chemotherapy used for treatment of cancer. [SOURCE]
