Mitochondrial Complex V deficiency, also known as ATP synthase deficiency or ATPAF2-related mitochondrial disorder, is a genetic condition affecting the function of mitochondrial complex V. This complex, also called ATP synthase, is responsible for the production of the majority of ATP in cells. ATP is the main energy source for various cellular processes, and its deficiency can lead to a wide range of developmental and metabolic abnormalities.

Patient with mitochondrial complex V deficiency may present with a variety of symptoms, including muscle weakness, developmental delays, intellectual disability, and heart problems. The severity of the condition can vary widely, with some patients experiencing more mild symptoms and others having life-threatening complications. Mitochondrial complex V deficiency is considered a rare condition, and its precise frequency is not well-known.

The genetic basis of mitochondrial complex V deficiency is complex, with mutations in various genes implicated in the condition. Some of the genes associated with mitochondrial complex V deficiency include ATPAF2, ATP12, and ATP5A1. Inheritance of the condition can be either autosomal recessive or mitochondrial, depending on the gene involved.

Strong references and resources for learning more about mitochondrial complex V deficiency and related conditions can be found in scientific databases such as PubMed, OMIM, and the Human Gene Mutation Database. These sources contain a wealth of information on the genetic, biochemical, and clinical aspects of mitochondrial complex V deficiency. Additionally, advocacy organizations and patient support groups can provide valuable resources and support for individuals and families affected by mitochondrial complex V deficiency.

Frequency

Mitochondrial complex V deficiency is a rare genetic condition affecting the function of the mitochondrial complex V, also known as ATP synthase. It is a rare condition and there is limited information available on its frequency.

The condition is typically inherited in an autosomal recessive manner, meaning that both parents must carry a copy of the mutated gene in order for their child to be affected. It can manifest with a wide range of features, affecting various organs and systems within the body.

Denied health insurance claims are a major problem for patients in America. The Kaiser Family Foundation found that ACA marketplace plans denied about 17% of in-network claims in 2019.

While precise frequency data is not readily available, the disease is considered rare in the general population. It has been associated with mutations in several genes, including ATP12, ATP5F1, ATP5G1, and ATP5E. These genes are involved in the function of complex V and oxidative phosphorylation.
