Common Genetic Markers for Autoimmune Disease

Common Genetic Markers for Autoimmune Disease

Autoimmune diseases are a complex group of disorders where the body’s immune system mistakenly attacks its own healthy tissues. These diseases can manifest in various ways, affecting different parts of the body, including the nervous system, cognitive function, immunity, and more. 

Ideally, we want to catch autoimmune diseases before they worsen and become chronic. 

One way to do this is through genetic testing. Most autoimmune conditions correlate with specific genetic markers. If you have these markers, then you may be more susceptible to autoimmune disease. But while genetics play a factor in how disease expresses itself in your body, your genes aren’t the only factor. Even if you have specific autoimmune disease genetic markers, proper nutrition, lifestyle, and wellness habits can keep you healthy or delay symptom progression.

If a family member has had an autoimmune disease, or if you’re wondering if you carry certain genetic markers for autoimmune diseases, the next step is testing. At Entelechy Life, we have all of our clients undergo advanced testing. We look at your blood, gut, and genes to get a full picture of your health. Once we understand the full story, we can start recommending wellness plans that are customized to your unique body type.

The Many Faces of Autoimmune Disease

Autoimmune disease is a broad category, and symptoms can show up in different ways. Some symptoms are quite general, like chronic fatigue, and this makes diagnosis and treatment challenging. Because symptoms can look different for different people, it’s important to do genetic testing, especially early on before symptoms are fully present.

Some presentations of autoimmune diseases include the following:

• Neuropathy

Autoimmune neuropathies, such as Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy (CIDP), affect the peripheral nervous system. These conditions can lead to weakness, numbness, and tingling in the limbs, potentially causing significant disability.

• Cognitive Dysfunction

Some autoimmune diseases, such as multiple sclerosis (MS) and neuropsychiatric systemic lupus erythematosus (NPSLE), can impact cognitive function. Patients may experience memory problems, difficulty concentrating, and mood disturbances.

• Low Immunity

Autoimmune diseases can compromise the immune system, leaving individuals more susceptible to infections. Conditions such as common variable immunodeficiency (CVID) and selective IgA deficiency can weaken the body’s defense mechanisms.

• Skin Conditions

Dermatological manifestations are common in autoimmune diseases, including conditions such as psoriasis and systemic sclerosis. These can result in skin rashes, ulcers, and changes in skin texture.

• Gastrointestinal Issues

Autoimmune diseases such as Crohn’s disease and celiac disease target the digestive system, causing symptoms such as abdominal pain, diarrhea, and malabsorption of nutrients.

• Joint Inflammation

Rheumatoid arthritis and ankylosing spondylitis are autoimmune diseases that primarily affect the joints, leading to pain, stiffness, and joint deformities.

Common Genetic Markers of Autoimmune Disease

While autoimmune diseases can affect anyone, individuals with a family history of these conditions are at a higher risk. Genetics plays a substantial role in determining susceptibility to autoimmune diseases. Several genetic markers have been identified as potential risk factors for these conditions. 

Here are six genetic markers associated with autoimmune diseases:

1. HLA Complex

The Human Leukocyte Antigen (HLA) complex, located on chromosome 6, is a cluster of genes involved in immune system regulation. Specific HLA alleles, such as HLA-DRB1 in rheumatoid arthritis and HLA-DQ2/DQ8 in celiac disease, are strongly associated with increased susceptibility to these respective autoimmune diseases.

2. CTLA-4 (Cytotoxic T-Lymphocyte Antigen 4)

CTLA-4 is a gene that encodes a protein responsible for regulating immune responses. Variations in the CTLA-4 gene have been linked to autoimmune diseases such as type 1 diabetes, Graves’ disease, and systemic lupus erythematosus (SLE).

3. PTPN22 (Protein Tyrosine Phosphatase Non-Receptor Type 22)

The PTPN22 gene is involved in immune cell signaling. Certain variants of PTPN22, such as the R620W polymorphism, have been associated with an increased risk of autoimmune diseases such as rheumatoid arthritis, type 1 diabetes, and systemic lupus erythematosus.

4. TNFAIP3 (Tumor Necrosis Factor Alpha-Induced Protein 3)

This genetic marker for autoimmune disease encodes a protein that regulates inflammation. Variations in TNFAIP3 have been linked to autoimmune diseases, including rheumatoid arthritis, systemic lupus erythematosus, and psoriasis.

5. IL23R (Interleukin-23 Receptor)

The IL23R gene is involved in the regulation of the immune response, particularly in inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis. Certain genetic variants of IL23R have been associated with an increased risk of these conditions.

6. IFIH1 (Interferon-Induced Helicase C Domain-Containing Protein 1)

Variations in the IFIH1 gene have been linked to an increased risk of autoimmune diseases such as type 1 diabetes, systemic lupus erythematosus, and multiple sclerosis. IFIH1 is also involved in the immune system’s response to viral infections.

Genetics Aren’t the Only Factor Impacting Autoimmune Disease

It’s important to understand that genetics alone do not determine the development of autoimmune diseases. So these genetic markers don’t always mean autoimmune disease. Epigenetics, the science of how genes are activated by environment and lifestyle, is important. Various factors contribute to disease onset and progression, so focusing on these areas can help prevent or manage autoimmune disease. 

First, diet plays a crucial role in autoimmune disease management. Certain diets, such as the Mediterranean diet or an anti-inflammatory diet rich in fruits, vegetables, and omega-3 fatty acids, may help reduce inflammation and alleviate symptoms.

Your environment, such as exposure to infections, toxins, and pollutants, can trigger autoimmune diseases or exacerbate existing conditions. For example, smoking is known to worsen symptoms in individuals with rheumatoid arthritis. Heavy metals or pesticides may also contribute to the development of autoimmune diseases in genetically susceptible individuals.

Chronic stress can negatively impact the immune system and exacerbate autoimmune disease symptoms. Stress management techniques, such as mindfulness and relaxation exercises, may be beneficial for individuals with autoimmune diseases. Hormonal changes, such as those that occur during puberty, pregnancy, or menopause, can influence the course of autoimmune diseases. For example, some women with autoimmune diseases experience symptom improvement during pregnancy.

Certain viral or bacterial infections can trigger or exacerbate autoimmune diseases. For instance, the Epstein-Barr virus has been associated with an increased risk of developing multiple sclerosis.

Some medications, such as certain immunosuppressants or drugs used in cancer treatment, can lead to autoimmune-like reactions or exacerbate existing autoimmune diseases.

Finally, the gut microbiome plays a critical role in immune system regulation. An imbalance in gut bacteria composition has been linked to autoimmune diseases such as inflammatory bowel disease.
