The ABCC8 gene provides instructions for making one part (subunit) of the ATP-sensitive potassium (KATP) channels that are found in specialized pancreas cells called beta cells. These KATP channels consist of eight subunits: four of these subunits ar READ MORE

The ABCC9 gene provides instructions for making the sulfonylurea receptor 2 (SUR2) protein. This protein forms one part (subunit) of a channel that transports charged atoms of potassium (potassium ions) across cell membranes. Each of these channels c READ MORE

The ABCD1 gene provides instructions for producing the adrenoleukodystrophy protein (ALDP). ALDP is located in the membranes of cell structures called peroxisomes. Peroxisomes are small sacs within cells that process many types of molecules. ALDP bri READ MORE

The ABCD4 gene provides instructions for making a protein that is involved in the conversion of vitamin B12 (also known as cobalamin) into one of two molecules, adenosylcobalamin (AdoCbl) or methylcobalamin (MeCbl). AdoCbl is required for the normal READ MORE

The ABCG2 gene belongs to a group of genes called the ATP-binding cassette family; genes in this family provide instructions for making proteins that transport molecules across cell membranes. In the intestines, the ABCG2 protein helps release (secre READ MORE

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 . Sterolin is involved in eliminating plant sterols READ MORE

The ABCG8 gene provides instructions for making sterolin-2, which makes up half of a protein called sterolin. The other half of the sterolin protein, sterolin-1, is produced from a gene called ABCG5 . Sterolin is involved in eliminating plant sterols READ MORE

The ABHD5 gene provides instructions for making a protein that turns on (activates) an enzyme called adipose triglyceride lipase (ATGL). The ATGL enzyme plays a role in breaking down fats called triglycerides, which are a major source of stored energ READ MORE

The ABL1 gene provides instructions for making a protein involved in many processes in cells throughout the body. The ABL1 protein functions as a kinase, which is an enzyme that changes the activity of other proteins by adding a cluster of oxygen and READ MORE

The ACAD8 gene provides instructions for making an enzyme called isobutyryl-CoA dehydrogenase (IBD). This enzyme is found in mitochondria, the energy-producing centers inside cells. The IBD enzyme is involved in breaking down proteins from food. Spec READ MORE

The ACAD9 gene provides instructions for making an enzyme that is found in mitochondria, the energy-producing structures inside cells. The ACAD9 enzyme is critical in helping assemble a group of proteins known as complex I. Complex I is one of severa READ MORE

The ACADM gene provides instructions for making an enzyme called medium-chain acyl-CoA dehydrogenase (MCAD). This enzyme functions within mitochondria, the energy-producing centers in cells. MCAD is essential for fatty acid oxidation, which is the mu READ MORE
