The XPA gene provides instructions for making a protein that is involved in repairing damaged DNA. DNA can be damaged by ultraviolet (UV) rays from sunlight and by toxic chemicals, radiation, and unstable molecules called free radicals. DNA damage oc READ MORE

The XK gene provides instructions for producing a protein that is found in various tissues of the body, particularly the brain, muscle, and heart. This protein is also present on the surface of red blood cells and carries a molecule known as the Kx b READ MORE

The XIAP gene provides instructions for making a protein that is found in many types of cells, including immune cells. It helps protect these cells from self-destructing (undergoing apoptosis) by blocking (inhibiting) the action of certain enzymes ca READ MORE

The XDH gene provides instructions for making an enzyme called xanthine dehydrogenase. This enzyme is involved in the normal breakdown of purines, which are building blocks of DNA and its chemical cousin, RNA. Specifically, it carries out the final t READ MORE

The WT1 gene provides instructions for making a protein that is necessary for the development of the kidneys and gonads (ovaries in females and testes in males) before birth. After birth, WT1 protein activity is limited to a structure known as the gl READ MORE

The WRN gene provides instructions for producing the Werner protein, which plays a critical role in repairing damaged DNA. The Werner protein functions as a type of enzyme called a helicase. Helicase enzymes generally unwind and separate double-stran READ MORE

The WNT5A gene is part of a large family of WNT genes, which play critical roles in development starting before birth. These genes provide instructions for making proteins that participate in chemical signaling pathways in the body. Wnt signaling con READ MORE

The WNT4 gene belongs to a family of WNT genes that play critical roles in development before birth. WNT genes provide instructions for making proteins that participate in chemical signaling pathways in the body. These pathways control the activity o READ MORE

The WNT3 gene is part of a large family of WNT genes, which play critical roles in development before birth. WNT genes provide instructions for making proteins that participate in chemical signaling pathways in the body. These pathways control the ac READ MORE

The WNT10A gene is part of a large family of WNT genes, which play critical roles in development starting before birth. These genes provide instructions for making proteins that participate in chemical signaling pathways in the body. Wnt signaling co READ MORE

The WNK4 gene provides instructions for making a protein that plays a role in blood pressure regulation by helping control the amount of sodium and potassium in the body. The WNK4 protein acts as a kinase, which is an enzyme that changes the activity READ MORE

The WNK1 gene provides instructions for making multiple versions (isoforms) of the WNK1 protein. The different WNK1 isoforms are important in several functions in the body, including blood pressure regulation and pain sensation. One isoform produced READ MORE
