Aspartylglucosaminuria

Overview

Aspartylglucosaminuria is a rare genetic disorder that affects how the body breaks down carbohydrates. People with this condition have trouble breaking down a certain type of sugar molecule called glycoasparagine from the foods they eat. This build-up of glycoasparagine can cause a range of symptoms, including developmental delays, joint stiffness, and intellectual disabilities. Aspartylglucosaminuria is caused by mutations in a gene that provides instructions for making an enzyme called aspartylglucosaminidase, which is necessary for breaking down glycoasparagine. The lack of this enzyme leads to the accumulation of glycoasparagine in the body, leading to the symptoms associated with the condition. Early diagnosis and management of aspartylglucosaminuria are important to help improve the quality of life for those affected by this disorder.

Causes of Aspartylglucosaminuria

Aspartylglucosaminuria is a genetic disorder that causes problems with the way the body breaks down certain materials. This disorder is caused by changes in a specific gene that provides instructions for making an enzyme called aspartylglucosaminidase. When this enzyme doesn't work correctly, the body can't break down a substance called aspartylglucosamine. This substance then builds up in the body and causes damage to cells and tissues, leading to the signs and symptoms of aspartylglucosaminuria.

Aspartylglucosaminuria is inherited in an autosomal recessive pattern, which means that a person must inherit two faulty copies of the gene (one from each parent) to develop the disorder. If a person only inherits one faulty gene, they are considered a carrier of the disorder but usually do not show any symptoms. The faulty gene responsible for aspartylglucosaminuria is more common in certain populations, such as the Finnish population. This disorder can be diagnosed through genetic testing and typically presents with symptoms such as intellectual disability, skeletal abnormalities, and facial features like a large head and widely spaced teeth.
