The SLC16A2 gene, also known as the monocarboxylate transporter 8 (MCT8) gene, is responsible for encoding a protein that plays a crucial role in the transport of thyroid hormones. This gene is located on the X chromosome, and mutations in it can result in Allan-Herndon-Dudley syndrome, a severe X-linked intellectual disability disorder. The SLC16A2 gene has been extensively studied, and a lot of information about its function and clinical relevance is available from various scientific articles, databases, and resources.

The SLC16A2 gene belongs to a family of solute carrier genes that encode transporters responsible for the transportation of various substrates across cell membranes. These transporters play critical roles in physiological processes, including the transport of nutrients, drugs, and metabolites. The SLC16A2 gene, specifically, is predominantly expressed in the central nervous system and is vital for normal psychomotor development and thyroid hormone action in the brain.

Researchers have identified several mutations in the SLC16A2 gene that are associated with Allan-Herndon-Dudley syndrome. This syndrome is characterized by severe intellectual disability, movement disorders, and abnormal thyroid hormone levels. Genetic testing for mutations in the SLC16A2 gene can help diagnose individuals with Allan-Herndon-Dudley syndrome.

The SLC16A2 gene is also the subject of ongoing scientific research to better understand its function and role in other diseases and conditions. It is listed in various genetic databases and catalog of genes, including the Online Mendelian Inheritance in Man (OMIM) database. In addition to the SLC16A2 gene, other genes involved in the thyroid hormone system are also listed in these resources, providing comprehensive information and references for healthcare professionals and researchers.

Genetic changes in the SLC16A2 gene have been identified to be related to various health conditions. SLC16A2 is a member of the solute carrier family 16 (monocarboxylic acid transporters), which plays a significant role in the transport of thyroid hormone across the cell membrane.

Genes Condition
SLC16A2 Allan-Herndon-Dudley syndrome
SLC16A2 Central nervous system-related conditions
SLC16A2 Psychomotor retardation
SLC16A2 X-linked intellectual disability

Genetic changes in SLC16A2 can lead to an excess of thyroid hormone in nerve cells, causing the above-mentioned health conditions. The variant testing and additional genetic tests can help identify these changes.

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.

References to these health conditions and related genes can be found in scientific articles, OMIM (Online Mendelian Inheritance in Man) database, PubMed, and other health databases. The Allan-Herndon-Dudley syndrome, for example, is listed in the OMIM registry with information on the related gene SLC16A2.

Allan-Herndon-Dudley syndrome

The Allan-Herndon-Dudley syndrome is a genetic disorder related to changes in the SLC16A2 gene. It is an X-linked condition that affects the central nervous system.

Patients with Allan-Herndon-Dudley syndrome often exhibit severe psychomotor retardation, which can result in intellectual disability. They may also have abnormal muscle tone and poor coordination.

The SLC16A2 gene encodes a monocarboxylate transporter, which is responsible for the transport of thyroid hormones into nerve cells. In individuals with Allan-Herndon-Dudley syndrome, this transporter is impaired, resulting in an excess of thyroid hormones in the central nervous system.

Testing for the Allan-Herndon-Dudley syndrome can be done through genetic testing, which identifies changes in the SLC16A2 gene. These changes can be further confirmed by additional testing, such as nerve conduction tests or imaging studies.

Mutations or changes in the SLC16A2 gene are linked to Allan-Herndon-Dudley syndrome, also referred to as X-linked intellectual disability type 30 or Reeser-Riley syndrome.

Allan-Herndon-Dudley syndrome is a rare X-linked genetic disorder characterized by severe intellectual disability and psychomotor retardation. It is caused by an impairment of the thyroid hormone transporter encoded by the SLC16A2 gene, leading to a deficiency of thyroid hormone in the nervous system.

Excess thyroid hormone levels have been found to lead to intellectual and developmental delays, poor muscle tone, and other neurological problems in individuals with this syndrome.

Further information about this gene and its associated conditions can be found in various scientific databases and health resources. The Online Mendelian Inheritance in Man (OMIM) catalog, for example, provides detailed information on genetic disorders, including Allan-Herndon-Dudley syndrome, and lists the SLC16A2 gene as the causative gene for this condition.

Diagnostic testing for genetic variants in the SLC16A2 gene can be performed through specialized genetic testing labs and clinics, which may offer targeted gene sequencing or panels for neurological and metabolic disorders. Clinical geneticists can provide further information and guidance on testing options for individuals suspected to have genetic conditions related to this gene.
