Hypomagnesemia with secondary hypocalcemia, also known as combined hypomagnesemia and hypocalcemia, is a rare genetic condition that impairs the function of the kidneys’ convoluted tubules. This condition is associated with a variety of neurological and other diseases, including impaired renal function and failure. It is caused by mutations in many different genes, with inheritance patterns that are often autosomal recessive.

Patients with hypomagnesemia with secondary hypocalcemia may present with symptoms such as seizures, muscle spasms, and tetany, which are caused by the low levels of magnesium and calcium in the blood. The exact cause of the condition can vary depending on the specific gene mutation, and additional testing may be necessary to determine the underlying genetic cause in each patient.

Research studies have been conducted to better understand the causes and mechanisms of hypomagnesemia with secondary hypocalcemia. Scientific articles and references related to this condition can be found in the OMIM catalog, PubMed, and other research databases. Clinical trials and studies related to the condition can also be found on ClinicalTrials.gov, providing additional information and resources for patients and their families.

Support and advocacy organizations are available to provide information and support for individuals and families affected by hypomagnesemia with secondary hypocalcemia. These organizations can offer resources about the condition, clinical trials, genetic testing, and other relevant topics. They also play a role in raising awareness and funding for research to further understand and treat this rare genetic condition.

Frequency

Studies have shown that hypomagnesemia with secondary hypocalcemia is a rare condition. According to clinicaltrialsgov, information about the frequency of this condition is limited. However, it is believed to be a very rare disease, with only a few reported cases in the literature.

Hypomagnesemia with secondary hypocalcemia can be caused by various factors. The exact cause of this condition is not fully understood and further research is needed.

In studies, the artificial intelligence (AI) technology used in some online health services for preliminary screening before connecting patients with a doctor actually outperformed real physicians in terms of reaching an accurate diagnosis, CNN AI technology correctly diagnosed conditions in 81% of patients, compared to a 72% average for accurate diagnoses among real physicians over a five-year period.

According to pubmed, omim, and other scientific articles, several genes have been associated with hypomagnesemia with secondary hypocalcemia. These genes are involved in magnesium channel function in the convoluted tubules of the kidneys.

The frequency of hypomagnesemia with secondary hypocalcemia in the general population is not well-known, but it is considered to be a rare condition. This makes it challenging to gather sufficient patient samples for clinical trials and research studies.

More information about the frequency of hypomagnesemia with secondary hypocalcemia can be found in the references section of this article. Genetic testing and clinical trials are ongoing to learn more about the causes, inheritance patterns, and additional clinical features of this condition.

For more resources and support for patients and families affected by hypomagnesemia with secondary hypocalcemia, the Seyberth Hypomagnesemia with Secondary Hypocalcemia Catalog provides a comprehensive list of genes and information on this condition.

Causes

The primary cause of hypomagnesemia with secondary hypocalcemia is mutations in the TRPM6 gene. TRPM6 is a channel protein that is responsible for the reabsorption of magnesium in the convoluted tubules of the kidneys. Failure of this gene impairs the function of the tubules and leads to magnesium loss in the urine, resulting in hypomagnesemia.

The TRPM6 gene is inherited in an autosomal recessive manner, meaning that both copies of the gene must be mutated for the condition to occur. Many different mutations in the TRPM6 gene have been identified, and they can vary in severity and clinical manifestations.

Secondary causes of hypomagnesemia with secondary hypocalcemia include certain medications, such as diuretics and proton pump inhibitors, and certain medical conditions, such as chronic alcoholism and malabsorption syndromes. In these cases, the underlying condition or medication use impairs the body’s ability to absorb magnesium, leading to low levels in the blood.

In some rare cases, other genetic diseases may also be associated with hypomagnesemia. For example, mutations in the CLDN16 or CLDN19 genes can cause familial hypomagnesemia with hypercalciuria and nephrocalcinosis, a condition characterized by excessive calcium excretion in the urine and the formation of calcium deposits in the kidneys.

More information about genetic testing for hypomagnesemia can be found on the Online Mendelian Inheritance in Man (OMIM) database and the ClinicalTrials.gov website. These resources provide information on ongoing research studies, clinical trials, and patient advocacy and support organizations related to hypomagnesemia and other genetic conditions.

Learn more about the gene associated with Hypomagnesemia with secondary hypocalcemia

Hypomagnesemia with secondary hypocalcemia is a condition caused by genetic variants that impair the function of certain channel genes in the convoluted tubules of the kidneys. These genes play a crucial role in regulating the balance of magnesium and calcium in the body.

There have been numerous studies and research conducted to understand the genetic basis of this condition. Scientists have identified several genes that can cause hypomagnesemia with secondary hypocalcemia when they are not functioning properly. These genes are responsible for the transport of magnesium ions in the kidneys, and any mutations or deletions in these genes can disrupt this process.

If you want to learn more about the specific gene associated with hypomagnesemia with secondary hypocalcemia, there are various resources you can refer to:

• Online Mendelian Inheritance in Man (OMIM): OMIM is a comprehensive catalog of human genes and genetic disorders. You can search for the gene associated with this condition, its function, inheritance frequency, and other relevant information.
• PubMed: PubMed is a database of scientific articles, including research papers and clinical studies. You can find studies that have investigated the genetic causes and mechanisms of hypomagnesemia with secondary hypocalcemia.

It is important to note that hypomagnesemia with secondary hypocalcemia is a rare condition, and comprehensive genetic testing may be required to identify the specific genetic cause in each patient. If you suspect you or a loved one may have this condition, it is best to consult with a healthcare professional for accurate diagnosis and appropriate management.

Inheritance

Hypomagnesemia with secondary hypocalcemia (HSH) has an autosomal recessive inheritance pattern. This means that an individual must inherit two copies of the mutated gene, one from each parent, in order to develop the condition. The condition was first described by Seyberth et al. in 2009, and since then, genetic testing has become available to confirm the presence of mutations in the gene that cause HSH.

The cause of HSH can be traced back to mutations in the CLDN16 gene, also known as the paracellin-1 gene. This gene is responsible for encoding a protein involved in the function of the kidney tubules, where it helps regulate the reabsorption of magnesium and calcium. Mutations in this gene impair the function of the protein, leading to the characteristic low levels of magnesium and calcium seen in individuals with HSH.

Additional resources for learning about the inheritance and genetics of HSH can be found on the Online Mendelian Inheritance in Man (OMIM) website, as well as scientific articles available on PubMed. These resources provide more information on the frequency of the condition, associated genes, and other research studies conducted on HSH.

In terms of clinical trials and patient advocacy, the ClinicalTrials.gov website provides information on ongoing research studies for HSH and other related diseases. This can be a valuable resource for individuals seeking more information or opportunities to participate in clinical trials for HSH.

Overall, the inheritance of HSH is a rare genetic condition that causes hypomagnesemia with secondary hypocalcemia. Genetic testing, research studies, and patient advocacy have provided additional support and resources for understanding and managing this condition.
