Heavy drinking can cause the number of oxygen-carrying red blood cells to be abnormally low. This condition, known as anemia, can trigger a host of symptoms, including fatigue, shortness of breath, and lightheadedness.
The human leukocyte antigen system or complex is a gene complex encoding the major histocompatibility complex proteins in humans. These cell-surface proteins are responsible for the regulation of the immune system in humans. The HLA gene complex resides on a 3 Mbp stretch within chromosome 6p21. HLA genes are highly polymorphic, which means that they have many different alleles, allowing them to fine-tune the adaptive immune system. The proteins encoded by certain genes are also known as antigen
Human leukocyte antigen (HLA) testing is performed when trying to find a suitable organ, tissue (bone marrow), or cord blood donor for transplantation. The results of either HLA class I or class II typing can be used for bone marrow transplant donor screening. This screening is coordinated with various agencies that conduct drives to assist people in need of a bone marrow transplant.
