Fumarase deficiency is a rare genetic condition that affects the body’s ability to convert fumarate to malate in the citric acid cycle. This impairment leads to a buildup of fumaric acid in the body, which can cause a range of symptoms and health problems.
Research on fumarase deficiency is ongoing, but currently there is limited information available about the condition. The Central database for genetic disorders (OMIM) provides some scientific articles and references about fumarase deficiency. Additional studies and clinical trials can be found on ClinicalTrials.gov.
The condition is inherited in an autosomal recessive manner, meaning that both copies of the fumarase gene must be altered to develop the deficiency. The frequency and names of fumarase deficiency may vary from patient to patient, and it is associated with other diseases and conditions.
Support and advocacy resources for fumarase deficiency are available from organizations such as Fumarase Deficiency Support and Advocacy Center. They provide information for patients and families affected by this rare condition.
For testing and diagnosis, genetic testing can be done to determine if there are alterations in the fumarase genes. This can help confirm the diagnosis of fumarase deficiency and guide treatment options.
Tomlinson et al. (year) conducted a study on the clinical and molecular characteristics of patients with fumarase deficiency. The study found that fumarase deficiency can present with a wide range of symptoms and can be associated with various neurological and developmental impairments.

In conclusion, fumarase deficiency is a rare genetic condition that affects the fumarase gene and impairs the conversion of fumarate to malate in the citric acid cycle. Further research and studies are needed to learn more about the causes, clinical presentations, and treatment options for this condition.
The frequency of fumarase deficiency is not precisely known, as it is a rare genetic condition. However, according to scientific studies and research, it is estimated to occur in less than 1 in every 1,000,000 people.
Support and advocacy organizations, such as the Fumarase Deficiency Support Group, provide resources and information for patients and their families. Additionally, the Genetics Home Reference and OMIM (Online Mendelian Inheritance in Man) catalog are valuable sources for further learning about this condition.
In terms of genetic inheritance, fumarase deficiency is usually inherited in an autosomal recessive manner. This means that both parents must carry a copy of the mutated gene in order for their child to develop the condition.
Clinical testing for fumarase deficiency can be done to confirm a diagnosis. Genetic testing can help identify mutations in the fumarate hydratase (FH) gene, which causes the impairment of this enzyme. Additional information about testing and other associated genes or diseases can be found on the NCBI Gene database.
Studies have shown that fumarase deficiency can result in a range of symptoms and health complications, including failure to thrive, developmental delays, neurological impairment, and progressive brain damage. These symptoms can vary from patient to patient.
