Biotinidase deficiency is a rare genetic condition that affects the body’s ability to process biotin, a vitamin essential for the breakdown of certain substances in the body. This condition is inherited in an autosomal recessive manner, meaning that individuals must inherit two copies of the mutated gene to develop the disease.

People with biotinidase deficiency have mutations in the BTD gene, which is responsible for producing the biotinidase enzyme. Without this enzyme, the body cannot effectively use biotin, leading to a buildup of toxic substances and a deficiency of biotin in the body. This can cause a range of symptoms, including skin rash, hair loss, seizures, developmental delay, and hearing loss.

Biotinidase deficiency is diagnosed through genetic testing, which can identify the specific mutations in the BTD gene. Early diagnosis and treatment are crucial for managing the disease and preventing long-term complications. Treatment involves taking biotin supplements to correct the deficiency and manage symptoms.

Additional resources and support for people with biotinidase deficiency and their families can be found through organizations such as the Biotinidase Deficiency Family Support Group and the National Organization for Rare Disorders (NORD). These organizations provide information, advocacy, and resources for individuals and families affected by this rare condition.

Research studies, clinical trials, and scientific articles on biotinidase deficiency can be found on websites such as PubMed, OMIM, and ClinicalTrials.gov. These resources provide valuable information on the causes, inheritance patterns, frequency, and management of this condition.

Further research and scientific advancements are needed to better understand biotinidase deficiency and develop more effective treatments. By raising awareness and supporting research efforts, we can improve outcomes for individuals with this rare genetic disease.

Nearly 60% of Americans surveyed support a Medicare for All program, according to Business Insider. Those in favor of Medicare for All include 75% of Democrats, 58% of registered Independents and 36% of Republicans, though Republican support jumps up to 64% when discussing an optional expanded Medicare program, also referred to as “Medicare for Some.”

Frequency

Biotinidase deficiency is a rare genetic disease. It occurs with a frequency of approximately 1 in 60,000 newborns in the general population.

The Center for Information & Study on Clinical Research Participation (CISCRP) reports that biotinidase deficiency is caused by mutations in the BTD gene. The BTD gene provides instructions for making the biotinidase enzyme, which is essential for breaking down biotin, a vitamin that plays a key role in the body’s energy metabolism. When the BTD gene is mutated, the biotinidase enzyme is not produced in sufficient quantities, resulting in a deficiency of biotin in the body.

According to the Online Mendelian Inheritance in Man (OMIM) catalog, biotinidase deficiency can lead to a range of symptoms and associated conditions, including hearing loss, neurological abnormalities, and skin rash. Additional names for this condition include biotin-dependent carboxylases deficiency and multiple carboxylase deficiency.

References in PubMed support the importance of genetic testing in identifying mutations in the BTD gene to confirm a diagnosis of biotinidase deficiency. ClinicalTrial.gov provides resources for patients and caregivers to learn more about biotinidase deficiency and participate in clinical trials and research studies.

Advocacy articles by Tokatli et al. in the journal Human Genetics highlight the clinical and genetic characteristics of biotinidase deficiency, supporting the need for early diagnosis and treatment for patients with this rare disease.

Overall, the scientific community recognizes the rarity of biotinidase deficiency and continues to conduct research on its causes, inheritance patterns, and potential treatments. Genetic testing and research studies play a vital role in advancing our understanding of this condition and developing interventions to support patients with biotinidase deficiency.

Causes

Biotinidase deficiency is caused by mutations in the BTD gene. The BTD gene provides instructions for making the enzyme biotinidase, which is needed to recycle biotin, a B-vitamin that is important for the body’s normal growth and development.

  • The BTD gene is located on chromosome 3 in humans.
  • Mutations in the BTD gene can result in reduced or absent biotinidase activity, leading to biotinidase deficiency.
  • Biotinidase deficiency is inherited in an autosomal recessive manner, which means that both copies of the gene must have mutations for the condition to occur.
  • Individuals with one mutated BTD gene are known as carriers and typically do not show symptoms of biotinidase deficiency.

Biotinidase deficiency is considered a rare genetic condition. The exact frequency is unknown, but it is estimated to occur in approximately 1 in every 60,000 to 120,000 individuals in the general population.

Additional information about the causes of biotinidase deficiency can be found in the OMIM entry for this condition (OMIM: ).

Genetic testing can be done to identify mutations in the BTD gene, which can confirm a diagnosis of biotinidase deficiency.

Research studies on the genetic causes of biotinidase deficiency, as well as other genetic diseases, can be found on the PubMed database and other scientific resources.

Learn more about the gene associated with Biotinidase deficiency

Biotinidase deficiency is a rare genetic condition caused by mutations in the BTD gene. This gene provides instructions for making the biotinidase enzyme, which is responsible for recycling biotin (a B-vitamin) in the body. Biotinidase deficiency is an autosomal recessive disorder, meaning that individuals must inherit two copies of the mutated gene – one from each parent – to develop the condition.

Individuals with this gene mutation have reduced or absent biotinidase enzyme activity, leading to a biotin-dependent condition. Biotin is essential for the function of several carboxylases, which are enzymes involved in important metabolic processes. Therefore, the lack of biotin recycling leads to a deficiency of these carboxylases, resulting in a variety of symptoms and health issues.

Genetic and Rare Diseases Information Center

The Genetic and Rare Diseases Information Center (GARD) provides information about the biotinidase deficiency, a rare genetic condition that affects the body’s ability to process biotin. This condition is also known by other names, including biotinidase deficiency, biotin deficiency type 1, and partial biotinidase deficiency.

Biotinidase deficiency is caused by mutations in the BTD gene, which provides instructions for making the biotinidase enzyme. Without enough biotinidase, the body cannot fully utilize biotin from the diet, leading to a range of symptoms and health problems.

The inheritance pattern of biotinidase deficiency is autosomal recessive, which means that an affected individual must inherit two copies of the mutated gene (one from each parent) to develop the condition. Individuals who inherit only one copy of the mutated gene are known as carriers and typically do not have any symptoms.

Biotinidase deficiency can present with a variety of signs and symptoms, including developmental delays, seizures, weak muscle tone, hearing and vision problems, and skin rashes. The severity of the condition can vary widely, even among affected individuals in the same family.

The frequency of biotinidase deficiency in the general population is estimated to be 1 in 60,000 to 1 in 80,000 births. However, the condition may be more common in certain populations, such as people of Turkish descent. It affects both males and females equally.

Diagnosis of biotinidase deficiency is made through specialized testing that looks for mutations in the BTD gene or measures the activity of the biotinidase enzyme in the blood. Early diagnosis and treatment are crucial to prevent or correct the symptoms associated with biotinidase deficiency.

Patient support and advocacy groups can provide additional information and resources for individuals and families affected by biotinidase deficiency.
