The AHCY gene, also known as the S-adenosylhomocysteine hydrolase gene, provides instructions for making an enzyme called S-adenosylhomocysteine hydrolase. This enzyme plays a crucial role in a process called methylation, which is involved in the regulation of gene activity. The AHCY gene is located on chromosome 20 and contains instructions for making a protein that is involved in the breakdown of S-adenosylhomocysteine.
Changes in the AHCY gene can lead to various genetic conditions, including hypermethioninemia with S-adenosylhomocysteine hydrolase deficiency (hypermethioninemia, AHCY-related). This condition is characterized by elevated levels of methionine in the blood due to a deficiency of the S-adenosylhomocysteine hydrolase enzyme. Symptoms may include developmental delay, intellectual disability, and liver problems.
For additional information on the AHCY gene, genetic testing, and related diseases, you can refer to various resources such as the Online Mendelian Inheritance in Man (OMIM) database, PubMed articles, and scientific literature. These databases provide comprehensive information on the gene, genetic variants, and associated diseases.
In addition to the AHCY gene, there are many other genes involved in the regulation of methylation and related genetic conditions. The AHCY gene is just one piece of the puzzle, and understanding its role in the context of other genes and genetic pathways is essential for a comprehensive understanding of these conditions. The Genetic Testing Registry and other genetic databases also list information on testing options and available resources.

Health Conditions Related to Genetic Changes
Genetic changes can have a significant impact on an individual’s health and can be linked to various health conditions. Scientific research and advances in genetic testing have allowed for a better understanding of these conditions and their underlying genetic causes.
The problem isn’t a shortage of people wanting to be doctors, but rather, too few opportunities for training. Medical schools have increased class sizes by 30% since 2002, but federal funding for residency training – an essential step in the process of becoming a practicing physician – has not increased since 1997, according to Inside Higher Ed.
One gene that has been identified as being associated with certain health conditions is the AHCY gene. This gene is responsible for producing an enzyme called S-adenosylhomocysteine hydrolase, which plays a role in methylation processes in the body. Methylation is a chemical modification of DNA that can affect gene expression and other important cellular functions.
Changes in the AHCY gene can lead to health conditions such as hypermethioninemia, which is characterized by elevated levels of methionine in the blood. Hypermethioninemia can have various symptoms and can be detected through genetic testing.
Hypermethioninemia
Hypermethioninemia is a genetic condition characterized by an increased level of methionine in the blood. Methionine is an essential amino acid that plays a role in various biochemical reactions in the body.
References to this condition can be found in scientific articles and databases such as PubMed, OMIM, and the Genetic Testing Registry. These resources provide information on the genetic changes in the AHCY gene that can lead to hypermethioninemia.
This condition can be diagnosed through genetic testing, which analyzes the AHCY gene for any changes. Additional tests may be conducted to assess the level of methylation in the body.
There are various articles and resources available on hypermethioninemia, including the Rados catalog of genetic diseases and the Sarnavka registry. These resources provide information on the symptoms, treatment, and management of hypermethioninemia.
Other genes and compounds listed in these resources may be related to hypermethioninemia. Variant scientific names may also be used to refer to this condition.
Other Names for This Gene
The AHCY gene is also known by several other names:
- Methionine adenosyltransferase 2, alpha (MAT2A)-Methyltransferase (protein)
- AHCY gene coding for Adenosylhomocysteinase (gene symbol)
- Hypermethioninemia due to adenosylhomocysteinase deficiency (condition)
- AHCY hypermethioninemia (variant)
- AHCY protein
These alternative names are used in different contexts and by different resources. Some of them refer to the gene itself, while others describe the protein or certain conditions related to changes in this gene.
For further information about the AHCY gene, methylation testing, related health conditions, and additional scientific articles and resources, you can refer to databases such as OMIM, PubMed, and the Genetic Testing Registry. These resources provide comprehensive information on the AHCY gene and its various names, as well as related diseases and testing methodologies.
