Red Hair Genes and Melanoma

red hair genes and melanoma

Did you know that red hair genes and melanoma are linked even if you don't have red hair? If the gene is in your family, you may be at higher risk for melanoma. You don't need to be a red head for this to increase your melanoma risk. Nope, you only need to have inherited a gene, whether it expressed as red hair or was overridden by one of the other hair color genes such as brown, black or blond. This is a really important new scientific finding.

Inheriting the gene for red hair is linked to melanoma even without having red hair!

A recent scientific study has discovered that simply having red hair and fair skin in your family may put you at a 42% increased risk for melanoma. All you may need is to inherit a single copy of the gene for red hair to share the heightened cancer risk of your ginger relatives.  It turns out it’s the gene that's the risk factor, not just the milky-fair skin that often comes with having red hair.

For years, we dermatologists have known that patients with red hair and their very pale skin are at higher risk of melanoma. We attributed the risk to the relative lack of melanin and the different type of melanin in their skin. Now we know that melanin is only part of the story.

Genes are still a relatively new scientific frontier for scientists, and in this discovery phase it appears that inheriting the red hair gene itself is enough to put you at higher melanoma risk. This means that even without actually looking like a redhead you can be at risk just because you inherited a red hair gene (called MC1R) from one of your parents. In other words, you can be a brunette with skin that sometimes burns and mostly tans, known as Fitzpatrick Skin Type 3, but be at higher risk for melanoma because you inherited a red hair gene. You just don't realize that you have the gene because it's not dominating your hair and skin color.

Before diving into the science, let me suggest that if you have the red hair gene, use a really good antioxidant skin cream (the green tea polyphenols are the ones I think have the best scientific proof) and a broad spectrum zinc oxide SPF 30+ sunscreen every day. - Dermatologist Dr. Bailey

The MC1R Gene: What is it and how does it increase the risk for melanoma?

The Melanocortin 1 Receptor gene, or MC1R gene, regulates the type of pigment your melanocytes make for your skin and hair.

Melanocytes are small cells that are scattered in your skin and hair follicles; they make all of your pigment including your natural hair and skin color as well as your tans and freckles.

  • The MC1R gene expressing melanocytes for red hair make a light red/orange pigment called pheomelanin. 
  • The MC1R gene expressing melanocytes for normal brown pigment make the more common brown melanin called eumelanin.

You get one MC1R gene from your mom and one from your dad. The combination of the two will determine your hair color and skin tone.

  • Bright ginger redheads have 2 MC1R that code for red hair and fair skin. They will have Fitzpatrick type 1 or 2 skin that burns easily, rarely (if ever) tans, and freckles when exposed to the sun.
  • Blondes and brunettes may have one MC1R gene coding for red, and one coding for brown. They may also have two coding for brown.

If a parent has an MC1R gene coding for red pigment they can pass that red hair gene on to their kids, who may or may not be redheads depending on if they got a red or brown one from their other parent.

You don’t need to have bright red hair to have the MCR1 gene for red hair - and its higher risk of melanoma.

You may have blond or brown hair and darker skin, but if you have just one redhead MC1R gene, that means that your skin and hair melanocytes produce the red pheomelanin pigment as well as the brown eumelanin pigment. So, while you may not have the red hair or fair skin, that one redhead gene is still in your DNA, and that alone puts you at increased risk of melanoma! To quote directly from the study investigators:

"carrying one or more of the MC1R red hair genes increased risk of melanoma mutations by 42% compared with people who do not have any MC1R gene. Age was also associated with an increased risk.…..This (study) suggests that the majority of persons with one MC1R gene, who do not have a red hair/sun sensitive phenotype (characteristic), may still be highly susceptible to the mutagenic effects of UV light (aka prone to Melanoma when they get sun or tanning bed UV ray exposure)."

Paraphrased, if you or someone you love has inherited the MC1R gene for red hair, there may be as much as a 42% increased risk of developing melanoma compared with people who don’t have one or two of those genes. Also, people with the MC1R gene developed melanoma at a younger age and in fact, having the gene was like adding 21 years of wear and tear to the skin in terms of melanoma age-related risk!

Skin pigment in red heads is also cancer causing even without UV rays!

There’s one more bit of bad news to add to this study before we turn to some good news. When we combine this new information with that of a 2012 study that showed pheomelanin to be cancer causing even without the sun, it feels like a double hit to redheads! Yep, pheomelanin can form DNA-damaging free radicals in the skin all by itself, even without the sun. It’s sort of like a DNA auto-destruct mechanism in the skin that can run on its own. Dear Darwin, it’s hard to understand how that was an evolutionary survival advantage for redheads!

This new study adds yet another layer of worrisome news linking melanoma to anyone who has inherited one of the genes for red hair – like me! Who here thinks unraveling the mystery of human genetics and correlating our gene-coding for heightened risk of killer diseases is getting depressing?! As a blond with red highlights and a great grand uncle who was a bright orange ginger, I'm talking about my family. Plus, I also inherited the BRCA mutation for breast and ovarian cancer. I sure could worry about my genes but I would rather figure out how to lower my risk of getting all the cancers my genes predispose me to. So… on to good news, being proactive and setting up self-care for living well.

Here’s my dermatologist's recommendations for people that carry even one MC1R gene for red hair:

Bottom line as I see it is that there are 3 key things to be done to reduce the risk of getting a serious melanoma if you have red hair in your family:

  1. Find a good dermatologist for annual skin exams and learn how to do monthly self-exams to detect melanoma between your doctor visits.
  2. Get your sun protection strategy perfected.
  3. Keep your body and skin filled with antioxidants:

We know that free radicals form from UV and from normal cellular activities. It means your body always needs to defend itself from them. Antioxidants neutralize free radicals before they damage precious structures such as DNA. You want your skin filled with an abundant supply of the best proven antioxidants to protect it from free radical damage. This is especially true for red heads!

Let's take these 3 recommendations one at a time:

First, get an annual skin exam by a board certified dermatologist and do monthly self-exams. Know the signs of melanoma, learn your own skin’s pattern of non-cancerous freckles and moles and work with your dermatologist to catch melanoma early.  Caught early, a Melanoma can truly be just an inconvenience that can be removed with simple outpatient skin surgery. When advanced however, Melanoma is life changing and can be deadly.

Become a pro about sun protection.  

We know that the sunburn and freckle prone skin of redheads is not designed for the sun.  Now, even the ‘genetically inclined’ to red hair need to be more careful. Let me teach you how to build the best sun protection for your skin while you enjoy life outdoors. It's not just sunscreen, you need to know about.

  1. Cover as much of your skin as you can with UPF 50 clothing when you are outdoors in the sun in intense UV expousre. I trust Coolibar UPF 50 clothing for my skin.
  2. Apply only the best sunscreens on uncovered skin daily (and use them correctly). I recommend only zinc oxide mineral based sunscreens. Click here to see the sunscreens I trust. 
  3. Shade your skin by seeking or create shade when you are outside. Click here to see my entire collection of sunscreens, sun protection hats and more. 
  4. Know how intense your UV exposure is so that you are certain to be well protected. Click here for my UV Detecto Ring. 

Load your body and skin with antioxidants.

Ensure that your diet provides an abundant supply of antioxidants at all times. You want them hanging around to respond when needed to the free radical popcorning that is going on from the sun or the spontaneously frisky pheomelanin. Eat your fruit and veggies, give ‘em the rainbow of antioxidants to really douse them with the best. Click here for my Diet Recommendations for healthy skin and more.

Build a skin care routine with the best proven antioxidant rich products. These need to be made from formulas that can get the antioxidants through your skin’s outer surface.  Those include green tea and vitamin C, vitamin A and vitamin E (which can cause allergies so care must be taken). My personal preference is green tea!

Is the red head gene the whole story with melanoma?

No, but it is a big piece of it. To put it in perspective:

  • 1-2% of the world’s population are red haired.
  • 16% of melanoma patients have red hair.
  • 26-40% of melanoma patients carry the MC1R gene.  That means that 60 to 74% of melanoma patients don’t carry the gene, but they still get melanoma.

A final and important point: Everyone needs sun protection. Everyone needs to learn how to identify melanoma. Everyone with a history of sun exposure or a family history of melanoma needs annual professional skin exams and everyone needs a rich dose of DNA protecting antioxidants in their body. Doctor’s orders! The MC1R gene and pheomelanin is becoming a big part of the melanoma story, but it’s not the entire story.
