ABCB8


ABCB8: A Gene with Far-Reaching Implications for Health and Disease

Description

ABCB8, also known as the ATP-binding cassette subfamily B member 8, is a gene that encodes a protein involved in the transport of cholesterol, phospholipids, and other molecules across cell membranes. It plays a critical role in regulating cholesterol levels in the body and has been implicated in various diseases, including cardiovascular disorders, neurological conditions, and cancer.

Associated Diseases

Dysregulation of ABCB8 has been associated with a wide range of diseases, including:

  • Atherosclerosis: ABCB8 helps regulate cholesterol efflux from macrophages, specialized immune cells that play a role in the development of atherosclerosis. Reduced ABCB8 activity impairs cholesterol removal, leading to plaque formation in arteries and increasing the risk of cardiovascular events.
  • Alzheimer‘s disease: ABCB8 is involved in the transport of amyloid-beta, a protein that forms toxic plaques in the brains of Alzheimer‘s disease patients. Impaired ABCB8 function may contribute to the accumulation of amyloid-beta and the development of Alzheimer‘s disease.
  • Schizophrenia: ABCB8 has been associated with schizophrenia, a severe mental illness. Studies have shown that variations in the ABCB8 gene may increase the risk of developing schizophrenia.
  • Cancer: ABCB8 is involved in the transport of chemotherapy drugs across cell membranes. Reduced ABCB8 activity can lead to increased drug resistance in cancer cells, making it more difficult to treat certain types of cancer.

Did you Know ?

  • Individuals with a specific mutation in the ABCB8 gene have a nearly 3-fold increased risk of developing atherosclerosis compared to those without the mutation.
