Which disease or disorder results from deficiency of ABCG5 and ABCG8?

Which disease or disorder results from deficiency of ABCG5 and ABCG8?

Phytosterolemia is a rare autosomal-recessive disease caused by a mutation in two genes (ABCG5 and ABCG8) encoding the ABC half-transporters.

What does ABCG5 do?

The ABCG5 gene provides instructions for making sterolin-1, which makes up half of a protein called sterolin. The other half of the sterolin protein, sterolin-2, is produced from a gene called ABCG8.

What is another name for ABCA1?

Function of ABCA1 Membrane Protein ABCA1, also known as cholesterol efflux regulatory protein (CERP), functions as a cholesterol membrane transporter involved in the regulation of cellular cholesterol and phospholipid homeostasis.

Where is ABCA1 located?

The ABCA1 protein is produced in many tissues, with high amounts found in the liver and in immune system cells called macrophages. This protein moves cholesterol and certain fats called phospholipids across the cell membrane to the outside of the cell.

What chromosome is ABCA1 on?

What is another name for Tangier disease?

Tangier disease, also known as familial alpha lipoprotein deficiency, is an extremely rare, inherited condition that was first described in a child on Tangier Island, an island located off of the coast of Virginia.

What is ABCB1 gene?

ABCB1 is an environment susceptible gene that codes for P-glycoprotein (P-gp). P-gp is responsible for multidrug resistance during chemotherapy of breast cancer. Six different non-synonymous Single Nucleotide Polymorphism (nsSNPs) of human ABCB1 gene were found in COSMIC database.

How is Tangier disease treated?

Treatment of Tangier disease is supportive and based on specific disease manifestations in a given individual. There are no known specific treatments for Tangier disease. Surgical removal of the spleen, tonsils, or other enlarged tissues may become necessary in some patients.

What is Tangier disease caused by?

Mutations in the ABCA1 gene cause Tangier disease. This gene provides instructions for making a protein that releases cholesterol and phospholipids from cells. These substances are used to make HDL , which transports them to the liver .

How do you get Tangier disease?

What does ABCG5 and ABCG8 do?

Two proteins, ABCG5 and ABCG8, encoded by the sitosterolemia locus, work as obligate dimers to pump sterols out of hepatocytes and enterocytes. ABCG5/ABCG8 are key in regulating whole-body sterol trafficking, by eliminating sterols via the biliary tree as well as the intestinal tract.

What does abcabcg5 and ABCG8 do for sitosterolemia?

ABCG5 and ABCG8: more than a defense against xenosterols The elucidation of the molecular basis of the rare disease, sitosterolemia, has revolutionized our mechanistic understanding of how dietary sterols are excreted and how cholesterol is eliminated from the body.

What is the ABCG8 variant of gallstone disease?

Genetic variant 19H of ABCG8 is associated with coronary artery disease. SNP D19H, but not SNP T400K, in the ABCG8 gene is significantly associated with GSD in an Indian population. Twins carrying a heterozygous or homozygous ABCG8 D19H genotype have a significantly increased risk of gallstone disease.

Is ABCG8 rs11887534 a risk factor for biliary tract cancer?

ABCG8 rs11887534, identified as a gallstone risk single-nucleotide polymorphism by whole genome scan, is also associated with an increased risk of biliary tract cancer A systematic review and meta-analysis of ABCG8 polymorphisms and association with markers of cholesterol metabolism.
