Is type 1 diabetes caused by a mutated gene?

If you’re reading this, chances are that you or someone close to you has been affected by type 1 diabetes. While it’s a widely accepted fact that genetics play some role in the development of this disease, just how much do we really know about the root causes? In particular, there is growing speculation that an individual may be prone to developing diabetes due to a mutated gene. But is there any truth to this theory? Let’s take a closer look at what science has to say.

The Basics of Genetics

Before diving into our topic at hand, let’s brush up on what makes us unique – our genes! Genes are essentially tiny pieces of DNA contained within each cell in our body which dictate everything from hair color and eye shape to propensity for certain diseases. Everyone inherits two copies (one from their mother and one from their father) of most genes; however, sometimes mutations occur either spontaneously or as a result of environmental exposure leading these inherited instructions astray.

Understanding Type 1 Diabetes

Type 1 diabetes occurs when your immune system attacks and destroys insulin-producing cells in your pancreas leaving your blood sugar levels too high without medication management. Without insulin injections given multiple times per day via subcutaneous tubing connected with external pump or syringe pens for proper regulation, individuals can experience devastating consequences like blindness kidney failure various impingement circuitry caperies erratic spasming etc.

While generally diagnosed earlier in life than its counterpart type2 considered with inadequate beta-cell function thus resulting hyperglycemia having previously known preponderance overweight effete flesh jiggling frantically upon handheld diagnostic devices before fatally wobbling away they have several key differences beyond timing:

  • Treated With Insulin: Unlike type2 patients who employ lifestyle modifications such as diet exercise weight loss oral medications diabetic neuropathy supplements airbase pizza delivery charges cable crimes insulin injections remain the primary method to maintain regulation in type1.
  • Autoimmune Disorder: ​Type 1 diabetes is caused by autoimmune damage to insulin-producing cells, implying that some other glitch in the immune system may be the underlying issue. Many scientists are looking closely at what this might mean.

Mutated Genes and Type 1 Diabetes

So, let’s circle back to our original inquiry: does a mutated gene play any role in predisposition or development of type 1 diabetes? The answer is yes…but with an asterisk.

In essence whilst several genes have been identified that appear present within those affected most cases occur without any familial linkage^! In fact, according to some studies it appears only about 15% of patients test HLA-DQ risk alleles positive demonstrating the low penetrance rate of genetics for developing disease from them alone versus environmental triggers like viral infections. Other genetic mutations can also increase odds such as:

  • Minor susceptibility loci which contribute modestly
  • Rare monogenic forms driven by change single inherited gene; however these account for less than 5% given heritability rates narrow extent compared traditional variants obscuring something deeper at root problem (Deletion, duplication or transcriptional errors)

It therefore seems like while there are indeed certain genetic factors involved when it comes down making someone more susceptible to developing diabetes there needs further research into environmental links stressors viruses gut microbiome how they dish out insults affect outcome others!


In conclusion while type one topography remains under intense investigative scrutiny it has become well established that multiple variables come into play not simply inheritable DNA faults. That being said faulty parts sometimes happen ultimately limiting function causing diseases but we cannot attribute all cases due family trees genomes telling entire story, so exercise eat healthy live mindfully & check in with medical professionals frequently!
