Question: Is Fibromyalgia Hereditary?

Several people in my family have had fibromyalgia and now I’m showing a lot of the symptoms. Is fibromyalgia hereditary?

Answer: Based on research, the current belief is that fibromyalgia is not hereditary in the classical sense, where a mutation is responsible for a given trait (monogenic), like with blue eye color; however, evidence does suggest that your genes can predispose you to fibromyalgia, but in a complex way involving many genes (polygenic).

What’s the Difference?

In a classical monogenic hereditary condition, the specific genes you get from your parents are the primary determining factor in whether you’ll get a disease. For example, in cystic fibrosis, the child of parents who are both disease carriers has a 25% chance of developing cystic fibrosis.

With polygenic predisposition, it’s not as simple or as certain because your genes only mean that a particular illness is possible under the right conditions. Typically, other factors come into play to actually trigger an illness.

In fibromyalgia, these other factors may include other sources of chronic pain, autoimmune disease, sleep disorders, chronic stress, infectious illness or abnormal brain chemistry. Some experts hypothesize that environmental things such as food sensitivities or exposure to toxins could also play a role.

Genetic Links in Fibromyalgia

Researchers began looking into a possible genetic component of fibromyalgia because it does tend to run in families. A 1989 study looked at siblings and parents of fibromyalgia patients and found that 52% of them had characteristic symptoms and other findings of fibromyalgia but had not been diagnosed with it. Another 22% didn’t have symptoms but did have evidence of abnormal muscle consistency. Later research confirmed the high rate of occurrence in families and showed that low pain threshold also appeared common in relatives of people with fibromyalgia.

We’re really just beginning to get a picture of the specific genetic factors associated with fibromyalgia. So far, we have multiple studies suggesting connections with numerous genes but many of these studies have not been replicated.

Genetic abnormalities that have been suggested by preliminary studies include genes that deal with neurotransmitters/hormones that have been implicated in fibromyalgia, including serotonin, norepinephrine, dopamine, GABA and glutamate. Others are involved in general brain function, inhibiting viral replication, and brain receptors for opioids and cannabinoids.

As we learn more about these genetic associations, researchers may identify which of them contributes to the risk of developing fibromyalgia as well as whether any can be used to diagnose or treat the condition.

About Michelle Arbore

I am 36 years old, married for 8 years and have an almost 3 year old, Michael Richard. We also have two cats (Anibel & Mama). I own my own social media management and coaching business that allows me to work from home. I like to read, listen to music, take photos, learn new things, shop, watch TV and spend time with family and friends. I also suffer from Fibromyalgia. I have suffered from this disease for over 15 years now. I started my blog so I could have a place to vent about what I am feeling. It has turned into a place where I post information about this disease, talk about books that I am reading about Fibro, and getting to meet other people who suffer from this.
