The HGD gene is a gene that is associated with several diseases. It is also known as homogentisate 1,2-dioxygenase, and it plays a crucial role in the metabolism of homogentisic acid. Homogentisic acid is a substance that is involved in the breakdown of certain amino acids, and it is related to a condition called alkaptonuria. Alkaptonuria is a rare genetic disorder that causes a buildup of homogentisic acid in the body, leading to a variety of symptoms and health problems.

Researchers have identified several changes in the HGD gene that are associated with alkaptonuria. These changes, or variants, can alter the function of the gene and lead to the accumulation of homogentisic acid. The HGD gene is listed in the OMIM database, where researchers have compiled information on genetic conditions and the genes associated with them. The HGD gene is also included in the GeneTests registry, which provides information on genetic tests and related resources for various genes and conditions.

Additional information on the HGD gene can be found in scientific articles and research papers. Many of these articles can be accessed through databases such as PubMed, where researchers can search for relevant studies and publications. The HGD gene is also included in the Human Gene Mutation Database (HGMD), a comprehensive catalog of gene variants and their associated diseases.

Genetic testing for variants in the HGD gene can be useful for diagnosing alkaptonuria and other related conditions. Testing can help confirm a diagnosis, guide treatment decisions, and provide information about the risk of passing the condition on to future generations. Healthcare professionals and genetic counselors can provide more information and guidance on the testing process and its implications.

In summary, the HGD gene is involved in the breakdown of homogentisic acid and is associated with alkaptonuria and other related conditions. Variants in this gene can lead to the accumulation of homogentisic acid and the development of symptoms. Researchers have compiled information on the HGD gene in various databases and resources, providing valuable insights into its role and associated diseases.
