Klaaskeemias

Klaaskeemias is a rare genetic disorder characterized by the absence of the enzyme dihydroorotase, which is crucial for the synthesis of pyrimidine nucleotides. This deficiency leads to a buildup of orotic acid and its derivatives in the body, resulting in various clinical manifestations. The disorder is inherited in an autosomal recessive manner, meaning that an individual must inherit the defective gene from both parents to be affected.

The clinical features of klaaskeemias typically appear in the first few months of life and may include failure to thrive, developmental delay, seizures, and neurological abnormalities. The disorder can also cause metabolic acidosis, which is a condition characterized by an excess of acid in the body. In some cases, klaaskeemias may be associated with other genetic disorders, such as the Zellweger syndrome spectrum disorders.

The diagnosis of klaaskeemias is usually made through genetic testing, which can identify the specific mutation in the DHODH gene responsible for the disorder. Treatment options for klaaskeemias are limited and primarily focus on managing the symptoms and preventing complications. This may include dietary interventions, such as the restriction of pyrimidine-containing foods, and the use of medications to manage seizures and metabolic acidosis.

The prognosis for individuals with klaaskeemias varies depending on the severity of the clinical manifestations and the effectiveness of the treatment. In some cases, the disorder may be fatal in infancy, while in others, individuals may live into adulthood with the help of supportive care. Research into the underlying mechanisms of klaaskeemias and the development of new therapeutic strategies is ongoing, with the hope of improving outcomes for affected individuals.
