The HNF1A gene provides instructions for making a protein called hepatocyte nuclear factor-1 alpha (HNF-1α). The HNF-1α protein acts as a transcription factor, which means it attaches (binds) to specific regions of DNA and helps control the activity READ MORE

The HNF1B gene provides instructions for making a protein called hepatocyte nuclear factor-1 beta (HNF-1β). This protein attaches (binds) to specific regions of DNA and regulates the activity of other genes. Based on this role, the protein is called READ MORE

The HNF4A gene provides instructions for making a protein called hepatocyte nuclear factor-4 alpha (HNF-4α). This protein plays an important role in the function of certain tissues and organs in the body. The HNF-4α protein acts as a transcription fa READ MORE

The HNRNPK gene provides instructions for making a protein called heterogenous nuclear ribonucleoprotein K (hnRNP K). This protein attaches (binds) to DNA or its chemical cousin RNA and to other proteins. It acts as a docking site to bring together d READ MORE

The HOGA1 gene provides instructions for making the 4-hydroxy-2-oxoglutarate aldolase (HOGA) enzyme. This enzyme is found in liver and kidney cells, specifically within structures called mitochondria, which are the energy-producing centers in cells. READ MORE

The HOXA13 gene provides instructions for producing a type of protein called a transcription factor. These proteins attach (bind) to specific regions of DNA and helps control the activity of other genes. The HOXA13 gene is part of a larger family gen READ MORE

The HOXB13 gene provides instructions for producing a protein that attaches (binds) to specific regions of DNA and regulates the activity of other genes. On the basis of this role, the protein produced from the HOXB13 gene is called a transcription f READ MORE

The HPD gene provides instructions for making an enzyme called 4-hydroxyphenylpyruvate dioxygenase. This enzyme is abundant in the liver, and smaller amounts are found in the kidneys. It is second in a series of five enzymes that work to break down t READ MORE

The HPRT1 gene provides instructions for producing an enzyme called hypoxanthine phosphoribosyltransferase 1. This enzyme allows cells to recycle purines, a type of building block of DNA and its chemical cousin RNA. Manufacturing purines uses more en READ MORE

The HPS1 gene provides instructions for making a protein that forms part of a complex called biogenesis of lysosome-related organelles complex-3 (BLOC-3). This complex plays a role in the formation of a group of cellular structures called lysosome-re READ MORE

The HPS3 gene provides instructions for making a protein that forms part of a complex called biogenesis of lysosome-related organelles complex-2 (BLOC-2). This complex plays a role in the formation of a group of cellular structures called lysosome-re READ MORE

The HPSE2 gene provides instructions for making a protein called heparanase 2. Little is known about this protein, but its structure is similar to that of another protein called heparanase 1. Heparanase 1 is an enzyme that splits (cleaves) molecules READ MORE
