The DDX11 gene provides instructions for making an enzyme called ChlR1, which functions as a helicase. Helicases are enzymes that attach (bind) to DNA and temporarily unwind the two spiral strands (double helix) of the DNA molecule so it can be copie READ MORE

The DEPDC5 gene provides instructions for making a protein that is part of a larger group of proteins (a complex) called GATOR1. This complex is made up of the DEPDC5 protein and proteins made from two other genes: NPRL2 and NPRL3. GATOR1 is found in READ MORE

The DES gene provides instructions for making a protein called desmin. Desmin is found in heart (cardiac) muscle and in the muscles used for movement (skeletal muscle). Within muscle fibers, structures called sarcomeres generate the force needed for READ MORE

The DGUOK gene provides instructions for making the enzyme deoxyguanosine kinase. This enzyme plays a critical role in mitochondria, which are the energy-producing centers inside the cell. Mitochondria each contain their own DNA, known as mitochondri READ MORE

The DHCR24 gene provides instructions for making an enzyme called 24-dehydrocholesterol reductase. This enzyme is involved in multiple pathways that produce cholesterol. Cholesterol is a waxy, fat-like substance that can be obtained from foods that c READ MORE

The DHCR7 gene provides instructions for making an enzyme called 7-dehydrocholesterol reductase. This enzyme is responsible for the final step in cholesterol production in many types of cells. Specifically, 7-dehydrocholesterol reductase converts a m READ MORE

The DHH gene provides instructions for making a member of the hedgehog protein family. Hedgehog proteins are important for early development in many parts of the body. The protein produced from the DHH gene is believed to be involved in male-typical READ MORE

The DHODH gene provides instructions for making an enzyme called dihydroorotate dehydrogenase. This enzyme is involved in producing pyrimidines, which are building blocks of DNA and its chemical cousin RNA. Dihydroorotate dehydrogenase is found in mi READ MORE

The DICER1 gene provides instructions for making a protein that plays a role in regulating the activity (expression) of other genes. The Dicer protein aids in the production of a molecule called microRNA (miRNA). MicroRNAs are short lengths of RNA, a READ MORE

The DKC1 gene provides instructions for making a protein called dyskerin. This protein is involved in maintaining structures called telomeres, which are found at the ends of chromosomes. Telomeres help protect chromosomes from abnormally sticking tog READ MORE

The DLAT gene provides instructions for making the E2 enzyme (also known as dihydrolipoamide acetyltransferase), which is part of a large group of proteins called the pyruvate dehydrogenase complex. This complex comprises multiple copies of three enz READ MORE

The DLD gene provides instructions for making an enzyme called dihydrolipoamide dehydrogenase. This enzyme forms one part (subunit), called the E3 component, of several groups of enzymes that work together (enzyme complexes). These complexes are esse READ MORE
