Acatalasemia is a rare genetic condition characterized by the absence or extremely low levels of the enzyme catalase. Catalase plays a critical role in the breakdown of hydrogen peroxide, a harmful byproduct of cell metabolism. Without sufficient levels of catalase, hydrogen peroxide can accumulate in the body, leading to tissue damage and other health problems.

Acatalasemia is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene, one from each parent, in order to develop the condition. The gene associated with acatalasemia is known as CAT, and mutations in this gene are responsible for the absence or reduced activity of catalase.

Due to its rarity, acatalasemia is not well known in the general population. However, there are advocacy and support groups, such as the Acatalasemia Support Center, that provide information and resources for individuals and families affected by this condition. Additional information can also be found on websites like OMIM (Online Mendelian Inheritance in Man) and PubMed, which contain scientific articles and references related to acatalasemia and other catalase-related disorders.

The symptoms of acatalasemia can vary widely from mild to severe, and may include recurrent ulcers, gum disease, and other problems related to tissue damage caused by hydrogen peroxide accumulation. Diagnosis of acatalasemia can be confirmed through genetic testing, which can detect mutations in the CAT gene.

In cases where acatalasemia is suspected, it is important for patients to consult with a healthcare professional for a proper diagnosis and to learn about management options. While there is no specific treatment for acatalasemia, individuals with this condition may benefit from measures to minimize exposure to hydrogen peroxide and maintain good oral health. Close monitoring and regular check-ups are also recommended to address any potential complications or associated health issues.

In summary, acatalasemia is a rare genetic condition caused by mutations in the CAT gene, leading to the absence or low activity of the enzyme catalase. This condition can cause tissue damage and other health problems due to the accumulation of hydrogen peroxide in the body. Support and resources are available for individuals and families affected by acatalasemia, and genetic testing can confirm the diagnosis. Close medical supervision and regular check-ups are important for managing the condition and addressing any associated health complications.

The average length of the portion of a doctor appointment in which the patient actually sees the doctor is up from previous years, rising by about 12 seconds per year, according to Reuters. However, 60% of physicians report dissatisfaction with the amount of time they spend with their patients, athenaInsight Many doctors now spend more time on paperwork than seeing patients, and a primary care physician who spends 5 minutes of face-to-face time with a patient will spend another 19.3 minutes, on average, working on that patient’s electronic health records (EHRs).

Frequency

Acatalasemia, also known as hypocatalasemia, is a rare genetic condition that affects the body’s ability to break down hydrogen peroxide. Hydrogen peroxide is a chemical that is produced by cells as a byproduct of normal metabolism. In individuals with acatalasemia, there is a deficiency of the enzyme catalase, which is responsible for breaking down hydrogen peroxide into water and oxygen.

Acatalasemia is a very rare condition, with only a few hundred cases reported worldwide. It is most commonly seen in people of Japanese, Korean, and Chinese descent, but cases have been reported in other ethnic groups as well.

The exact cause of acatalasemia is not fully understood, but it is thought to be caused by mutations in the CAT gene, which provides instructions for making the catalase enzyme. These mutations can result in the production of an inactive or nonfunctional enzyme.

Acatalasemia is typically inherited in an autosomal recessive pattern, which means that an individual must inherit two copies of the mutated gene (one from each parent) in order to have the condition. Individuals who inherit only one copy of the mutated gene are carriers of the condition and do not usually have any health problems.

Additional information about the frequency of acatalasemia and other related diseases can be found in databases such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources provide scientific information about the condition, including the number of reported cases and any associated health problems.

Due to the rarity of acatalasemia, there may be limited resources and support available for patients and their families. However, advocacy groups and genetic testing centers can provide additional information and support for those affected by this condition.

Causes

Acatalasemia is a rare genetic condition in which the patient has a deficiency or complete absence of the enzyme catalase, resulting in various health problems. This condition is caused by mutations in the CAT gene, which provides instructions for making the catalase enzyme.

Most cases of acatalasemia are inherited in an autosomal recessive pattern, which means that both copies of the CAT gene in each cell have mutations. Individuals with only one mutated copy of the gene are carriers of the condition and do not typically experience any symptoms.

Acatalasemia is more common in certain populations, such as the Japanese population, where the frequency of the condition is estimated to be 1 in 30,000 individuals. However, it is considered a rare disease worldwide.

Other genetic diseases associated with acatalasemia include hypocatalasemia, which is characterized by decreased catalase activity, and peroxide ulcers syndrome, which is characterized by recurrent ulcers in the mouth and other mucous membranes.

To learn more about the causes of acatalasemia and related conditions, you can find additional information from sources such as scientific articles, the Online Mendelian Inheritance in Man (OMIM) database, PubMed, and genetic testing centers.

Inheritance

Acatalasemia is a rare genetic condition caused by mutations in the CAT gene that is responsible for producing the enzyme catalase. Catalase is an essential enzyme that helps break down hydrogen peroxide, a harmful byproduct of cell metabolism, into water and oxygen. Individuals with acatalasemia have low or absent levels of catalase, leading to an accumulation of hydrogen peroxide and subsequent health problems.

The inheritance of acatalasemia follows an autosomal recessive pattern, meaning that individuals must inherit two copies of the mutated CAT gene (one from each parent) in order to develop the condition. Carriers of a single copy of the mutated gene are typically unaffected but can pass the mutation on to their children.

Acatalasemia is a rare condition, and its frequency varies among different populations. It has been reported to be more common in individuals of Japanese descent, with around 1 in 3,000 individuals affected. On the other hand, acatalasemia is extremely rare in other populations.

In addition to acatalasemia, mutations in the CAT gene can also cause a similar condition called hypocatalasemia, which is characterized by low levels of catalase rather than its absence. Hypocatalasemia may have milder symptoms compared to acatalasemia.

There are currently no known additional health problems associated with acatalasemia or hypocatalasemia. Symptoms of acatalasemia can vary widely among individuals, but some common problems include oral ulcers, bleeding gums, frequent infections, and gray hair. However, it is important to note that not all individuals with acatalasemia will experience these symptoms.

Diagnosis of acatalasemia can be confirmed through genetic testing, which involves analyzing the CAT gene for mutations. Genetic counseling may be recommended for individuals with a family history of the condition or those who are carriers of the mutated gene.
