What are vitamin D receptor gene mutations?
VDR (Vitamin D Receptor) encodes the nuclear hormone receptor for vitamin D3, a protein called vitamin D receptor (VDR). Low or low normal vitamin D values, often seen in those with chronic illness and even the general population, can lead to vitamin D deficiency, which is related to a lot of neurological and immunological conditions. Vitamin D stimulates enzymes that create dopamine. VDR Tak and VDR Bsm are usually inverse from each other.
Receptor mutations in the vitamin D receptor can disrupt the body’s ability to utilize vitamin D signaling effectively, leading to various health issues such as vitamin D-resistant rickets and potential links to other diseases like prostate cancer and autoimmune disorders. These vitamin D receptor mutations, particularly in the VDR gene, can also impact bone health and the body’s ability to absorb calcium and phosphate.
So if there is a positive VDR Tak, there would be a negative VDR Bsm. However, this is not always the case. It has been clinically observed that the body may have trouble tolerating methyl donors with a COMT V158M and a VDR Taq positive status. VDR Taq negative individuals may already have higher levels of dopamine. But the combinations of variations COMT and VDR Taq can lead to a wide range of dopamine levels. Those that are VDR Taq positive and COMT negative may have the lowest dopamine levels.
Note: Some have pointed out that VDR Taq is reported backward. Since the majority of medical journals report a different risk allele or use different notation. These arguments are well-founded. Many claims about VDR and are clinical observations. There are no medical studies to support some of the observations.

When the vitamin D receptor gene is impaired, this can lead to many health problems. Vitamin D hormone is needed to break down into GcMAF which is then needed to attack stealth pathogens, viruses, and cancer cells.
Many chronically ill do not get out of the bed to get sulfated D from the sun. Also, many chronically ill people are low on GcMAF because they are low on D3 which needs to be sulfated and broken down into GcMAF. GcMAF which is one billionth of a gram in the blood is crucial. GcMAF has six attacks on cancer including the cannabinoid pathway.
We also see that many people with viral overloads, autism, cancer, and Lyme are GcMAF deficient. They may even have D levels close to 100 but they are not sulfating their D3 because of the following:
Eating GMO’d Roundup ready foods. Glyphosate converts into glyoxylate. Oxalates share the same transport system as sulfation. I call it oxalates “hogging” up the transport system. This causes poor sulfation of D3 where it cannot sulfate D3 into GcMAF.
Zinc is needed to sulfate D3
DAO is needed to sulfate D3
Lysine is needed to sulfate D3
P5P is needed to sulfate D3
B6 is needed to sulfate D3
Definition and Explanation of VDR Gene Mutation
A VDR gene mutation is a change in the DNA sequence of the vitamin D receptor (VDR) gene. One such condition is hereditary 1,25 dihydroxyvitamin D-resistant rickets (HVDRR), which arises from mutations in the VDR gene. VDR gene polymorphisms, which are variations in the VDR gene, can influence the metabolism of vitamin D and have implications for health, particularly in relation to insulin resistance and metabolic disturbances. The VDR gene provides instructions for making a protein called the vitamin D receptor, which is essential for the body’s ability to absorb calcium and maintain strong bones. When mutations occur in the VDR gene, they can affect the function of the VDR protein, leading to impaired calcium absorption and bone mineralization. These mutations can be inherited from one’s parents or occur spontaneously during fetal development. Understanding the role of the VDR gene is crucial, as it helps in identifying potential health issues related to vitamin D metabolism and bone health.
Causes and Prevalence of VDR Gene Mutation
The VDR gene mutation is a genetic disorder that affects the vitamin D receptor, leading to impaired calcium absorption and bone mineralization. This mutation is relatively rare, with an estimated prevalence of about 1 in 10,000 to 1 in 20,000 individuals. Interestingly, the mutation appears more frequently in individuals of European descent, particularly in Scandinavian countries.
In some cases, individuals may have compound heterozygous mutations, where different mutant alleles are inherited from each parent, contributing to the complexity of the condition. The exact causes of VDR gene mutations are not fully understood, but it is believed to be inherited in an autosomal recessive pattern. This means that an individual must inherit two copies of the mutated gene, one from each parent, to exhibit symptoms. Mutations in the VDR gene can lead to a range of health problems, including vitamin D-resistant rickets, osteomalacia, and autoimmune diseases. Understanding these genetic factors is crucial for early diagnosis and management of related health conditions.
Molecular Mechanisms of VDR Gene Mutation
VDR gene mutations can significantly alter the structure and function of the vitamin D receptor (VDR) protein, leading to impaired vitamin D signaling. The VDR protein is a nuclear receptor that plays a pivotal role in regulating calcium and phosphate metabolism, essential for maintaining bone health and overall physiological balance.
Mutations in the VDR gene can disrupt critical domains of the VDR protein, such as the ligand-binding domain, hormone-binding domain, or DNA-binding domain. These disruptions can hinder the protein’s ability to bind to vitamin D and interact with DNA, thereby impairing the regulation of genes involved in calcium and phosphate absorption. The VDR protein also interacts with other transcription factors, including the retinoid X receptor (RXR), to form a complex that regulates gene expression. Mutations can affect this interaction, further compromising vitamin D signaling.
The VDR protein is highly conserved across species, underscoring its importance in regulating calcium and phosphate metabolism. When mutations occur, they can lead to various diseases, including hereditary vitamin D-resistant rickets (HVDRR) and vitamin D-resistant rickets. These conditions are characterized by the body’s inability to respond adequately to vitamin D, resulting in impaired bone mineralization and other systemic issues.
Understanding the molecular mechanisms of VDR gene mutations is crucial for developing targeted therapies and managing conditions associated with impaired vitamin D signaling.
Function of the VDR Gene in Bone Health
The VDR gene plays a pivotal role in maintaining bone health by regulating calcium absorption and bone mineralization. The VDR protein binds to vitamin D, activating the expression of genes involved in bone mineralization. This process is facilitated by the interaction between the vitamin D receptor (VDR) and the retinoid X receptor (RXR), where RXR heterodimerization with VDR is essential for the protein’s functionality and its role in calcium and phosphate absorption. Additionally, the VDR protein regulates the activity of osteoblasts, the cells responsible for building bone. When the function of the VDR is impaired, it can lead to reduced bone mineral density, increasing the risk of osteoporosis and other bone-related disorders. Ensuring proper VDR function is essential for maintaining strong and healthy bones.
Symptoms and Health Conditions
VDR Problems / Symptoms
Impaired calcium absorption and bone mineralization due to disrupted calcium homeostasis. The vitamin D receptor (VDR) binds to vitamin D and interacts with the retinoid X receptor (RXR) to form a complex that attaches to specific DNA regions known as vitamin D response elements. This binding regulates the expression of vitamin D-responsive genes, which is crucial for controlling the absorption of essential minerals like calcium and phosphate.
Reduced bone mineral density
Increased risk of osteoporosis
Weakened immune system
Increased risk of autoimmune diseases
Impaired hair growth
Skin problems
Common Symptoms of VDR Gene Mutation
Individuals with VDR gene mutations may experience a range of symptoms, including:
Rickets or osteomalacia, which are conditions characterized by the softening of the bones
Weakened muscles, leading to fatigue and reduced physical strength
Hair loss and various skin problems
An increased risk of infections due to a weakened immune system
Genetic studies have shown that variations in the human vitamin D receptor gene (VDR) may influence insulin resistance and other metabolic syndromes, such as type 2 diabetes and polycystic ovary syndrome.
Scoliosis and its Link to VDR Gene Mutation
Scoliosis, an abnormal curvature of the spine, has been linked to VDR gene mutations. The active form of vitamin D, 1,25(OH)2D, plays a crucial role in bone health by mediating the actions of the vitamin D receptor (VDR), and mutations in the VDR gene can impair this process. Impaired VDR function can lead to reduced bone mineral density and weakened bones, contributing to the development of scoliosis. Early detection and treatment of VDR gene mutations are crucial in preventing or reducing the severity of scoliosis. By addressing the underlying genetic factors, it is possible to improve bone health and mitigate the risks associated with scoliosis.
Other Related Health Conditions
VDR gene mutations have been linked to several other health conditions beyond bone-related issues. The VDR interacts with the vitamin D response element to regulate the expression of genes involved in immune function and bone health. For instance, individuals with VDR gene mutations are at an increased risk of developing autoimmune diseases such as multiple sclerosis and type 1 diabetes. These conditions occur when the immune system mistakenly attacks the body’s own tissues, and impaired vitamin D signaling can exacerbate this process.
Additionally, VDR gene mutations are associated with a higher risk of osteoporosis, osteopenia, and fractures due to compromised bone mineralization. There is also evidence suggesting a link between VDR gene mutations and certain cancers, including colorectal and breast cancer. Furthermore, neurological disorders such as Parkinson’s disease and Alzheimer’s disease have been connected to these mutations, highlighting the broad impact of the VDR gene on overall health.
Genetic Disorders Associated with VDR Gene Mutation
Hereditary vitamin D-resistant rickets (HVDRR) is a rare genetic disorder caused by mutations in the VDR gene. This condition is characterized by the body’s impaired response to vitamin D, leading to rickets, alopecia, and other systemic symptoms. HVDRR is inherited in an autosomal recessive pattern, meaning that affected individuals must inherit two copies of the mutated gene, one from each parent, to exhibit symptoms.
In addition to HVDRR, mutations in the VDR gene can cause vitamin D-resistant rickets, a disease marked by impaired calcium absorption and inadequate bone mineralization. This condition can lead to severe skeletal deformities and other health issues if not properly managed.
Other genetic disorders associated with VDR gene mutations include alopecia areata, intervertebral disc disease, kidney stones, and leprosy. These conditions highlight the broad impact of VDR gene mutations on various physiological processes. For instance, alopecia areata involves hair loss due to immune system dysfunction, while intervertebral disc disease affects the spine’s structural integrity.
Understanding the genetic basis of these disorders is essential for early diagnosis and effective treatment. By identifying individuals at risk and providing targeted interventions, healthcare providers can improve patient outcomes and manage the complications associated with VDR gene mutations.

Cannabinoid Pathway
The VDR gene also plays a significant role in the regulation of the cannabinoid pathway, which is essential for maintaining bone health. This complex system involves the interaction of various receptors, including the CB1 and CB2 receptors, which are influenced by the VDR gene. When the VDR gene is mutated, it can disrupt the normal functioning of the cannabinoid pathway, leading to impaired bone health and an increased risk of osteoporosis.
The cannabinoid pathway is not only crucial for bone health but also for various physiological processes, including pain modulation and immune response. Therefore, understanding the impact of VDR gene mutations on this pathway can provide insights into potential therapeutic targets for improving bone health and managing related conditions.
Diagnosing VDR Gene Mutation
Diagnosing a VDR gene mutation typically involves a combination of genetic testing and clinical evaluation. Genetic testing can identify specific mutations in the VDR gene, providing a definitive diagnosis. This process usually involves analyzing a DNA sample obtained from a blood sample or cheek swab.
In addition to genetic testing, clinical evaluation is essential to assess the severity of the mutation and its impact on bone health. Measuring serum vitamin D levels can also aid in diagnosis, as individuals with VDR gene mutations often exhibit low levels of vitamin D. By combining these diagnostic methods, healthcare providers can develop a comprehensive understanding of the mutation and its effects, enabling more effective management and treatment strategies.
Genetic Testing for VDR Gene Mutations
Genetic testing for VDR gene mutations involves analyzing a sample of DNA to identify specific changes in the gene. This can include point mutations, deletions, and insertions that affect the function of the vitamin D receptor. The test can also identify carriers of the VDR gene mutation, who may be at risk of passing the mutation to their offspring.
Moreover, genetic testing can be used to monitor the effectiveness of treatment and to identify individuals who may be at risk of developing related health conditions. By understanding the genetic basis of VDR gene mutations, healthcare providers can offer personalized treatment plans and preventive measures to improve patient outcomes.
