Top 10 Genes to Check in Your Genetic Raw Data

It can be overwhelming when you are getting started with learning how your genes affect your health.

What’s actually important? Does it matter if something increases your risk of an obscure disease by a tiny bit?

Let me help to cut through some of the confusion with my personal list of what is important. Below are 10 genes with important variants that can have a big impact on health.

Check your genetic data — and read the articles to learn more if you do carry the variant.

#1) HFE Gene (hemochromatosis risk)

A couple of mutations in the HFE gene increase the amount of iron absorbed from food. This causes increased iron storage in various tissues in the body. Eventually, this can lead to hemochromatosis or iron overload. Symptoms of too much iron can include joint pain (often moving from joint to joint) and fatigue. Hemochromatosis can involve organ dysfunction as iron gets stored in the liver, pancreas, heart, skin, and brain. Read the full article on iron overload

Check your genetic data for rs1800562 (23andMe v4, v5; AncestryDNA):

  • A/A: most common cause of hereditary hemochromatosis, highest ferritin levels (two copies of C282Y)
  • A/G: increased ferritin levels, can cause hemochromatosis. Population frequency of about 5% in people with Caucasian/European heritage.

#2) F5 Gene (factor V Leiden blood clot risk)

Factor V is a clotting factor essential for forming blood clots.  A gene variant, known as factor V Leiden, increases the amount of factor V, which in turn can increase clotting. The variant is linked to an increased risk for blood clots including deep vein thrombosis. Read the full article on factor V Leiden

Check your genetic data for rs6025 (23andMe v4, v5; AncestryDNA):

  • C/C: typical
