Aromatase deficiency is a rare genetic disorder that affects the conversion of androgens to estrogens. It is more common in females, but can also appear in males. This deficiency causes a variety of symptoms, including hirsutism in women and delayed onset of puberty in both males and females.

There are several articles and scientific studies on aromatase deficiency that provide more information about this rare disease. It is associated with a gene called Cyp19a1, and its inheritance follows an autosomal recessive pattern. Aromatase deficiency is often diagnosed through genetic testing.

Signs and symptoms of aromatase deficiency can vary from person to person, but may include delayed onset of puberty, lack of breast development, low bone mineral density, and other typical signs of estrogen deficiency. Aromatase deficiency can also cause a variety of other diseases and conditions, and there are additional resources available for support and advocacy for those affected by this rare disease.

The frequency of aromatase deficiency is not well-documented, but it is considered to be a rare condition. The OMIM catalog provides more information about the genetics, clinical features, and other associated genes and diseases. PubMed is also a good resource for finding scientific articles and references on aromatase deficiency.

Frequency

The frequency of aromatase deficiency is rare. According to the OMIM catalog of human genes and genetic disorders, only a few cases have been reported.

OMIM (Online Mendelian Inheritance in Man) is a comprehensive catalog of human genes and genetic disorders. It provides information about the frequency, inheritance, signs and symptoms, and more for various genetic conditions.

It’s not just health insurance premiums, but also deductibles, that keep on rising. In 2018, the average deductible was $3,000 for a gold-tier family plan, $8,000 for a silver-tier family plan and $12,000 for a bronze-tier family plan, according to USC Annenberg’s Center for Health Journalism.

It is important to note that the frequency of aromatase deficiency may be underestimated, as there may be undiagnosed or unreported cases. Additionally, the condition may not be widely known or recognized by clinicians, leading to limited awareness and diagnosis.

In males, aromatase deficiency can manifest with hirsutism (excessive hair growth) and other signs of androgen excess. In females, the typical signs may not develop until after puberty. These signs can include delayed or absent puberty, primary amenorrhea (lack of menstrual periods), and infertility.

To learn more about aromatase deficiency, there are additional resources available. The OMIM catalog and PubMed, a database of scientific articles, can provide more information and references.

Patient advocacy and support groups can also provide information and resources for individuals and families affected by aromatase deficiency. These organizations can help connect individuals with genetic testing, provide support, and raise awareness about the condition.

Overall, while aromatase deficiency is a rare condition, it is important to continue raising awareness and understanding about it among clinicians and the general public. This can lead to earlier diagnosis and intervention, improving the lives of individuals with this genetic disorder.

Causes

Aromatase deficiency is a rare genetic condition that affects the conversion of androgens to estrogens. It is caused by mutations in the CYP19A1 gene, which codes for the aromatase enzyme.

There are several articles available on PubMed and other scientific resources that provide more information about the causes and inheritance of aromatase deficiency. The OMIM catalog is a valuable resource for learning more about this condition and the associated genes.

In females with aromatase deficiency, the typical signs and symptoms include hirsutism (excessive hair growth) and other masculinization features. In males with this condition, the signs may appear later in life and include delayed puberty and impaired bone development.

Testing for aromatase deficiency includes genetic testing to identify mutations in the CYP19A1 gene. Additional testing may be done to confirm the diagnosis or rule out other diseases that can cause similar symptoms.

It is important to note that aromatase deficiency is a rare condition, and there is limited information and support available for patients and their families. However, there are advocacy organizations and support groups that can provide resources and assistance.

Learn more about the gene associated with Aromatase deficiency

Aromatase deficiency is a rare genetic condition associated with the CYP19A1 gene. Aromatase is an enzyme encoded by the CYP19A1 gene that plays a crucial role in the conversion of androgens to estrogens. Mutations in this gene can lead to a decrease or complete absence of aromatase activity, resulting in a deficiency of estrogen production in both males and females.

Common signs and symptoms of aromatase deficiency in females include the absence or delay of puberty, irregular menstrual cycles, and infertility. In males, it can cause delayed puberty, bone maturation issues, and hirsutism. However, the symptoms can vary from person to person and may not always be typical.

Aromatase deficiency is a rare condition, and more scientific research is needed to fully understand its frequency and associated genes. The OMIM database (Online Mendelian Inheritance in Man) provides detailed information on the genetic causes and inheritance patterns of various diseases, including aromatase deficiency. PubMed and other scientific databases are also valuable resources for finding articles and references related to this genetic condition.

Genetic testing can help diagnose aromatase deficiency in patients who exhibit the signs and symptoms associated with the condition. It can also be beneficial for genetic counseling and family planning. Additionally, there are advocacy and support groups for individuals and families affected by aromatase deficiency, providing resources and information to help navigate the challenges associated with this rare genetic disease.

Learning more about the CYP19A1 gene and aromatase deficiency can provide valuable insights for patients, healthcare professionals, and researchers. With a better understanding of the genetic and biochemical mechanisms involved, we can develop targeted treatments, provide accurate diagnoses, and offer appropriate support to individuals with this rare condition.

Inheritance

Aromatase deficiency is a rare genetic condition associated with a deficiency in the aromatase enzyme. The frequency of this condition is not well known, but according to the OMIM catalog, there have been about 20 articles published about it.

This condition is more common in females, and it can develop in both males and females, but the signs and symptoms appear differently. In females, aromatase deficiency can cause hirsutism, which is the excessive growth of hair. In males, the signs and symptoms are less typical.

The inheritance of aromatase deficiency is autosomal recessive. This means that both parents must carry a copy of the mutated gene to pass it on to their child. If both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit the condition.

Genetic testing can be done to confirm the diagnosis of aromatase deficiency. This testing can be done on a fetus during pregnancy or on a sample of blood or other tissues after birth. Testing can identify mutations in the CYP19A1 gene, which is responsible for the production of aromatase.

Additional resources for patient support, advocacy, and information about aromatase deficiency can be found at the Genetic and Rare Diseases Information Center (GARD) and OMIM. These websites provide information on the causes, symptoms, and treatment options for this condition.

Other Names for This Condition

Aromatase deficiency is also known by other names, including:

• Estrogen insufficiency due to aromatase deficiency in females
• CYP19A1 deficiency
• Aromatase excess syndrome in males
• Estrogen insensitivity due to aromatase deficiency in females
• Aromatase deficiency in granulosa cells

These names reflect different aspects of the condition and may be used interchangeably.

Aromatase deficiency is a rare genetic condition that affects the conversion of androgens to estrogens. It is caused by mutations in the CYP19A1 gene, which provides instructions for making the aromatase enzyme. Without aromatase, the conversion of androgens to estrogens does not occur properly, leading to a deficiency of estrogens in affected individuals.

Aromatase deficiency can appear in both males and females, but its signs and symptoms are more typical in females. In affected females, it can cause delayed or absent puberty, infertility, and bones that age faster than normal. In males, aromatase deficiency is rare and may be associated with hirsutism (excessive hair growth) and other masculine characteristics.

Catalog of Genes and Diseases from OMIM

Aromatase deficiency is a rare condition associated with mutations in the CYP19A1 gene. These mutations can cause a reduction in or absence of the enzyme aromatase, which plays a crucial role in the conversion of androgens to estrogens.

This genetic disorder affects both males and females. In affected males, it can lead to atypical skeletal development, delayed bone maturation, and tall stature. Females with aromatase deficiency may experience hirsutism (excessive hair growth) and other signs of androgen excess, as well as delayed puberty.

The inheritance pattern of aromatase deficiency is autosomal recessive. This means that both copies of the CYP19A1 gene must be mutated for the condition to develop. Inheritance testing can help identify carriers of the mutated gene and provide valuable information for family planning and genetic counseling.
