Renal hypouricemia

Renal hypouricemia is a rare condition that affects the kidneys, causing a decrease in the amount of urate in the urine. Urate is a waste product that is usually eliminated from the body through the kidneys. The exact frequency of renal hypouricemia is not known, but it is thought to be more prevalent than previously thought.

Renal hypouricemia can be caused by mutations in several different genes. These genes are involved in the normal function of the kidneys and help regulate the amount of urate in the body. Individuals with renal hypouricemia may have mutations in one or more of these genes.

Renal hypouricemia is usually diagnosed through genetic testing. Testing for this condition can help determine the cause of the hypouricemia and guide treatment decisions. In some cases, additional testing may be needed to rule out other causes of the condition.

For individuals with renal hypouricemia, there are resources available to learn more about the condition and provide support. The National Kidney Foundation and other advocacy groups provide information for patients and resources for genetic testing. There are also clinical trials and research studies available for individuals interested in participating.

More information about renal hypouricemia and related diseases can be found in the OMIM and PubMed databases. These resources provide scientific articles and references on the condition and its associated genes.

Frequency

Renal hypouricemia is a rare condition that affects the kidneys’ ability to excrete urate, a waste product from the breakdown of purines in the body. While the exact prevalence of this condition is unknown, it is estimated to occur in about 1 in 25,000 individuals.

Even with health insurance, patients in the U. S. have a hard time affording their medical care. About one in five working-age Americans with health insurance, and more than half of those without health insurance, reported having trouble paying their medical bills in the last year, according to S. News & World Report.

This condition can be caused by mutations in several genes involved in the renal handling of urate. The most commonly associated genes include SLC22A12, URAT1, and ABCG2. However, more research is needed to understand the full spectrum of genes and their functional effects on renal urate handling.

Renal hypouricemia can be inherited in an autosomal recessive or autosomal dominant manner, depending on the underlying genetic cause. Autosomal recessive renal hypouricemia is more prevalent and is usually caused by mutations in the SLC22A12 or URAT1 genes.

Testing for renal hypouricemia can be done through genetic testing to identify mutations in the associated genes. This information is helpful for diagnosis and provides information on the inheritance pattern and potential recurrence risks for affected individuals and their family members.

Additional resources for further information and support include scientific articles available on PubMed and OMIM, as well as the Renal Hypouricemia section in the Online Mendelian Inheritance in Man (OMIM) catalog. ClinicalTrials.gov also provides information on ongoing studies related to renal hypouricemia.

In conclusion, renal hypouricemia is a rare condition that affects the kidneys’ ability to excrete urate. It is caused by mutations in genes involved in the renal handling of urate and can be inherited in an autosomal recessive or autosomal dominant manner. Although rare, there are resources available for individuals and their families to learn more about this condition and find support.

Causes

The causes of renal hypouricemia can be both genetic and acquired.

Genetic causes:

Renal hypouricemia can be caused by mutations in specific genes involved in urate transport and metabolism in the kidneys (SLC22A12, SLC2A9, and ABCG2).
Inheritance of two copies of the mutated gene from both parents can lead to renal hypouricemia.
These genetic mutations affect the function of urate transporters in the kidneys, resulting in decreased reabsorption and increased excretion of urate in the urine.

Acquired causes:

Some individuals may develop renal hypouricemia due to additional functional or acquired defects in urate transporters or other related genes.
This condition can also be seen in individuals with other renal diseases, such as chronic kidney disease or kidney damage from other underlying causes.

Testing for renal hypouricemia:

Testing for renal hypouricemia usually involves measuring urate levels in the blood and urine, as well as additional testing to assess the function of urate transporters in the kidneys.
Frequency of testing and additional investigations may vary depending on the clinical presentation and suspicion for renal hypouricemia.

More information about the causes of renal hypouricemia can be found in scientific articles and resources available on Pubmed and other renal research centers.
