Research

Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome, also known as HHH syndrome, is a rare genetic disorder that affects the body's ability to break down proteins properly. This condition is caused by mutations in the SLC25A15 gene, which provides instructions for making a protein called the mitochondrial ornithine transporter 1. This protein is essential for moving a molecule called ornithine into mitochondria, which are the energy-producing centers of cells. Without functional mitochondrial ornithine transporter 1, toxic levels of ammonia and ornithine can build up in the body, leading to serious health problems.

Individuals with HHH syndrome may experience symptoms such as confusion, seizures, developmental delays, and liver damage. The diagnosis of this condition is often based on clinical evaluation, biochemical tests, and genetic testing. Treatment for HHH syndrome focuses on managing symptoms and preventing complications. This may include a low-protein diet, medications to reduce ammonia levels, and supplements to help normalize levels of certain amino acids. Research into HHH syndrome is ongoing, with efforts focused on understanding the underlying mechanisms of the disease and developing new treatment options to improve the quality of life for affected individuals.

History of Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome

Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome is a rare genetic disorder that affects how the body processes amino acids, which are the building blocks of proteins. People with this syndrome have trouble breaking down and getting rid of certain amino acids, leading to a buildup of ammonia and other toxic substances in the blood and tissues.
