The SLC46A1 gene, also known as the proton-coupled folate transporter (PCFT) gene, belongs to the SLC46A gene family. It is a member of the solute carrier (SLC) superfamily that encodes transmembrane proteins involved in the transport of various substances across cell membranes. The SLC46A1 gene is responsible for encoding the PCFT protein, which is primarily found in the human intestine.
The PCFT protein plays a crucial role in the absorption of folates, a group of essential nutrients that are necessary for several biological processes in the body. Mutations or genetic changes in the SLC46A1 gene can lead to hereditary folate malabsorption (HFM), a rare genetic disorder characterized by severe folate deficiency. Individuals with HFM are unable to properly absorb folates from their diet, resulting in a range of health problems.
The identification of SLC46A1 gene variants associated with hereditary folate malabsorption has been made possible through advances in genetic testing and the use of central resources such as the Online Mendelian Inheritance in Man (OMIM) database and PubMed. Additional scientific articles and references related to the SLC46A1 gene can be found in these databases, providing valuable information for further study and understanding of its function and characterization.
Testing for genetic changes in the SLC46A1 gene is available through genetic testing labs and can be included in genetic panels that assess for various conditions and diseases related to folate metabolism. These genetic tests can help identify variants in the SLC46A1 gene that may be associated with hereditary folate malabsorption or other related disorders.
Overall, the SLC46A1 gene, also known as PCFT, is a crucial member of the SLC46A gene family and plays a central role in the absorption of folates in the human intestine. Understanding the function and genetic changes in this gene is important for the identification and management of hereditary folate malabsorption and related diseases.
Health Conditions Related to Genetic Changes
Genetic changes in the SLC46A1 gene can lead to various health conditions related to folate malabsorption. Folate is a vital vitamin that plays a crucial role in the cell’s growth and function. The SLC46A1 gene encodes a proton-coupled folate transporter that is responsible for the absorption of folates in the intestine.
It’s not just health insurance premiums, but also deductibles, that keep on rising. In 2018, the average deductible was $3,000 for a gold-tier family plan, $8,000 for a silver-tier family plan and $12,000 for a bronze-tier family plan, according to USC Annenberg’s Center for Health Journalism.
Genetic testing can identify changes in the SLC46A1 gene, helping to diagnose health conditions related to folate malabsorption. Some of these conditions are listed below:
- Hereditary Folate Malabsorption (HFM): HFM is a rare genetic disorder characterized by the impaired absorption of dietary folates in the intestine.
- Sakaris Syndrome: Sakaris syndrome is another name for hereditary folate malabsorption. It is a severe form of folate deficiency that can lead to various health problems.
- Pemetrexed Sensitivity: Pemetrexed is a chemotherapy drug that inhibits the function of folate. Individuals with hereditary folate malabsorption may have increased sensitivity to this drug.
More information about these conditions and other health issues related to genetic changes in the SLC46A1 gene can be found in scientific articles and databases. The Online Mendelian Inheritance in Man (OMIM) database and PubMed are valuable resources for accessing information on genetic diseases and related genes.
Characterization of the SLC46A1 gene and its function has provided valuable insights into the absorption and transport of folates in the human body. Additional studies and research are ongoing to further understand the role of this gene in health and disease.
The identification of genetic changes in the SLC46A1 gene is essential for the diagnosis and management of related health conditions. Genetic testing and the use of registries can help centralize information about affected individuals and contribute to the development of targeted therapies.

Hereditary folate malabsorption
Hereditary folate malabsorption is a genetic condition caused by changes in the SLC46A1 gene. This gene is responsible for the function of the proton-coupled folate transporter (PCFT), which is essential for the absorption of folates in the intestine.
Scientific research on hereditary folate malabsorption has been published in various articles listed in databases such as PubMed and OMIM. These articles provide information on the identification, characterization, and testing of genetic variants in the SLC46A1 gene.
Individuals with hereditary folate malabsorption have difficulties absorbing folates, which are essential for proper cell function. This can lead to a range of health problems, including anemia, neurological abnormalities, and impaired growth and development.
Diagnostic tests for hereditary folate malabsorption typically involve genetic testing to identify changes or mutations in the SLC46A1 gene. Additional tests may be performed to measure folate levels in the blood and urine.
Treatment options for hereditary folate malabsorption may include high-dose folate supplementation to overcome the impaired folate absorption. In some cases, other medications such as pemetrexed may also be used to manage the condition.
Family members of individuals with hereditary folate malabsorption may also undergo genetic testing to identify potential carriers of the genetic variant. This can be helpful for genetic counseling and family planning.
The SLC46A1 gene is just one of many genes involved in folate absorption and metabolism. There are other genetic variants and conditions related to folate metabolism, and further research is needed to fully understand the mechanisms and implications of these genetic changes.
Resources such as the National Institutes of Health’s Genetic Testing Registry and various health databases provide additional information and references on hereditary folate malabsorption and related conditions.

Genetic testing is available to identify changes in the SLC46A1 gene associated with central malabsorption of folates. The Genetic Testing Registry (GTR) lists various tests related to this gene. These tests can help in the diagnosis and identification of hereditary diseases and conditions.
Scientific articles available on PubMed provide further information on the characterization of the SLC46A1 gene and its role in folate absorption. Studies conducted on human cells and from animal models have contributed to our understanding of this gene’s function and its importance in overall health.
For further resources and databases, GTR provides a catalog of genetic tests conducted on the SLC46A1 gene. These tests can provide valuable information on the presence of specific variants and their implications in disease susceptibility.
In addition to central malabsorption of folates, mutations in the SLC46A1 gene have been associated with pemetrexed sensitivity and other folate-related conditions. These tests can help in the identification of individuals who may react differently to certain medications or have an increased risk for developing certain diseases.
Genetic testing can be a valuable tool in personalized medicine, allowing for targeted treatments that take into account an individual’s genetic makeup. The information obtained from these tests can aid in the development of personalized treatment plans and improve patient outcomes.
