The GALNT3 gene, also known as GALNAC-T3, encodes a protein that plays a crucial role in the post-translational modification of proteins. This gene is primarily expressed in the kidneys and helps maintain the reabsorption of calcium and phosphate in the body.

Research has found that mutations in the GALNT3 gene are associated with familial tumoral calcinosis, a rare genetic disease characterized by abnormal deposits of calcium phosphate in soft tissues. These mutations can lead to changes in the protein function, resulting in the inability to properly regulate calcium and phosphate levels.

Testing for GALNT3 gene mutations can be done through various methods, such as genetic sequencing and analysis. The OMIM database, as well as other scientific resources like PubMed, provide additional information and references about the gene and its related conditions.

Understanding the role of the GALNT3 gene is crucial for effectively diagnosing and managing conditions related to calcium and phosphate regulation. Research and genetic testing can help identify individuals with mutations in this gene, allowing for early intervention and treatment.

Overall, the GALNT3 gene plays a significant role in maintaining the balance of calcium and phosphate levels in the body. Further research and genetic studies are necessary to fully comprehend its function and potential implications for human health.

Health Conditions Related to Genetic Changes

Genetic changes in the GALNT3 gene have been associated with several health conditions. These changes can affect the function of the protein encoded by the gene, leading to various diseases and conditions.

Given the high cost of medical care, it’s hardly a shock that patients are drowning in medical debt. Almost 20% of American households have delinquent medical bills that affect their credit report, according to NBC News. Having medical bills in collections makes it more difficult for patients to engage in other economic activities, such as purchasing a home or securing a loan to start a business.

One of the conditions related to genetic changes in the GALNT3 gene is familial tumoral calcinosis (FTC). FTC is a rare genetic disorder characterized by the deposition of calcium in soft tissues, such as the skin and subcutaneous tissue. Genetic testing can help confirm the presence of GALNT3 gene changes in individuals with FTC.

Another condition associated with GALNT3 gene changes is hyperphosphatemic familial tumoral calcinosis (HFTC). HFTC is a subtype of familial tumoral calcinosis that involves excessive reabsorption of calcium and phosphate by the kidneys. This condition can result in the formation of calcifications throughout the body, including the joints and soft tissues.

Gene databases such as OMIM and PubMed provide additional information on the genetic changes and related health conditions associated with GALNT3. These resources can be helpful in understanding the impact of GALNT3 gene changes on health.

Scientific articles listed in PubMed can provide more information on specific health conditions and the role of GALNT3 gene changes in these conditions. These articles can be a valuable source of information for researchers and healthcare professionals.

Furthermore, the GALNT3 gene is also known by other gene names, such as GALNT-3 and PP110. These alternative names can be used to search for related information in scientific literature and databases.

In summary, genetic changes in the GALNT3 gene can lead to various health conditions, including familial tumoral calcinosis and hyperphosphatemic familial tumoral calcinosis. Resources such as OMIM, PubMed, and gene databases provide information on these conditions and help maintain a catalog of genetic changes found in GALNT3. Further research and testing are necessary to fully understand the impact of GALNT3 gene changes on health and develop targeted treatments for related diseases.

Hyperphosphatemic familial tumoral calcinosis

Hyperphosphatemic familial tumoral calcinosis is a genetic condition that plays a role in the abnormal accumulation of calcium deposits in the body tissues. It is caused by changes (variants) in the GALNT3 gene.

The GALNT3 gene provides instructions for making a protein called polypeptide N-acetylgalactosaminyltransferase 3. This protein is involved in the addition of sugar molecules to other proteins, a process known as glycosylation. Glycosylation is important for protein function and regulation.

In hyperphosphatemic familial tumoral calcinosis, certain changes in the GALNT3 gene impair the ability of the protein to function properly. As a result, calcium and phosphate are not reabsorbed properly in the kidneys, leading to high levels of these minerals in the blood. This excess calcium and phosphate can then accumulate in soft tissues, such as the skin, joints, and blood vessels, causing the formation of calcified masses or tumors.

Hyperphosphatemic familial tumoral calcinosis is listed as a genetic condition in various scientific resources, including the Online Mendelian Inheritance in Man (OMIM) database and the Genetic Testing Registry (GTR). These databases provide information on genes, genetic conditions, and genetic tests.

Other related conditions involving changes in the GALNT3 gene include familial tumoral calcinosis and normophosphatemic familial tumoral calcinosis.
