Inborn disorder of pyrimidine metabolism

Researchers are testing a combination of two drugs, doxecitine and doxribtimine, in adults with thymidine kinase 2 (TK2) deficiency, a rare genetic condition that causes muscle weakness and breathing problems. The study will enroll about 15 adults with moderate to severe disease.…

This program provides access to two experimental drugs, doxecitine and doxribtimine, for people with thymine kinase 2 deficiency (TK2d), a rare genetic disorder that can cause severe muscle weakness and early death. It is for children and adults who have a confirmed TK2 gene muta…

This study tests a different chemotherapy drug (trifluridine/tipiracil) for people with metastatic colorectal or gastroesophageal cancer who have a genetic condition (DPD deficiency) that makes standard chemo very toxic. About 73 participants will receive this drug along with oth…

This study aims to learn more about rare disorders that affect how the body processes chemicals called pyrimidines and purines. These disorders can cause problems in the brain, blood, kidneys, and immune system, ranging from mild to life-threatening. Researchers will compare test…

This study creates a global registry for people with mitochondrial disorders—rare diseases that affect energy production in cells. By collecting health data from 6,000 participants worldwide, researchers aim to understand how these diseases progress and identify the best ways to …

This study gathers medical information from people with MNGIE, a rare genetic disease that affects the nerves and digestive system. Researchers want to learn how the disease progresses and find better ways to measure it. Up to 50 patients worldwide can join, and no new treatments…
