Aromatase Excess Syndrome (AES) is a rare genetic condition caused by mutations in the CYP19A1 gene. This gene provides instructions for making an enzyme called aromatase, which converts androgens into estrogens. In individuals with AES, the CYP19A1 gene is overactive, resulting in excessive production of estrogens and a deficiency of androgens.

One of the main symptoms of AES is a high frequency of menstrual bleeding in females, starting at an early age. This can be accompanied by excessive growth and bone maturation, leading to abnormally tall stature and accelerated bone age. AES can also cause other symptoms such as hirsutism (excessive hair growth) in females and gynecomastia (breast development) in males.

AES is a rare condition, with only a few documented cases in the medical literature. It is inherited in an autosomal dominant pattern, which means that an affected individual has a 50% chance of passing the condition on to each of their children. AES can be diagnosed through genetic testing, specifically testing for mutations in the CYP19A1 gene.

There is currently no cure for AES, but symptoms can be managed through hormonal therapy. Treatment may involve the use of aromatase inhibitors to suppress estrogen production and restore the balance between estrogens and androgens. Regular monitoring and evaluation are important to assess the effectiveness of treatment and ensure optimal hormone levels.

In addition, bone growth and other complications associated with excess androgens can be managed with appropriate medical interventions, such as hormone therapy.

Causes

Aromatase excess syndrome is a rare condition caused by genetic changes in the CYP19A1 gene. This gene provides instructions for making an enzyme called aromatase, which converts androgens (male hormones) into estrogens (female hormones).

Excess aromatase activity leads to the overproduction of estrogens, causing a range of symptoms including accelerated growth, early puberty in girls, and irregular menstrual cycles in women.

Most cases of aromatase excess syndrome are caused by genetic mutations in the CYP19A1 gene. These mutations can be inherited in an autosomal dominant pattern, which means that a person only needs one copy of the mutated gene to develop the condition. In some cases, the genetic changes occur spontaneously and are not inherited from either parent.

There are other rare conditions and diseases associated with excess aromatase activity. These include familial gynecomastia, which is a condition that causes breast enlargement in males, and aromatase deficiency, which leads to a lack of estrogens.

Testing for genetic determinants of aromatase excess syndrome can be done through specialized genetic testing laboratories. Resources like OMIM and PubMed provide additional scientific information about the condition and references to articles with more patient and family information. Patient advocacy and support organizations, such as the Aromatase Excess Support Center, offer information and support for individuals and families affected by this rare genetic condition.

Inheritance

Aromatase excess syndrome is a rare genetic condition caused by mutations in the CYP19A1 gene. This gene provides instructions for making an enzyme called aromatase, which plays a key role in the production of estrogens from androgens (male hormones). In individuals with aromatase excess syndrome, the gene mutation results in increased aromatase activity, leading to an overproduction of estrogens.

The inheritance pattern of aromatase excess syndrome is autosomal dominant. This means that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition. If a parent carries the mutated gene, there is a 50% chance that each of their children will inherit the gene and be affected by the condition.

It is important for individuals with aromatase excess syndrome and their family members to receive genetic testing and counseling. Genetic testing can confirm the presence of the CYP19A1 gene mutation and provide information on the likelihood of passing the gene on to future generations. Genetic counseling can help individuals and families understand the implications of the genetic mutation and provide support and resources.

For more information on the inheritance and genetic causes of aromatase excess syndrome, additional resources can be found online. The OMIM catalog (Online Mendelian Inheritance in Man) contains detailed information on the CYP19A1 gene and associated diseases. PubMed and other scientific articles can also provide more information on the condition and its inheritance.
