Wilson’s disease: ATP7B gene mutations and copper in the brain
Mutations in ATP7B can cause copper dysregulation and Wilson’s disease. People carrying one copy of the mutation may also have subtle changes.
Unusual and Rare
Uncommon and rare mutations can impact your health. Knowing about these can give you a heads-up as to whether you need to talk with your doctor.
Please keep in mind that most direct-to-consumer genetic tests aren’t guaranteed to be clinically accurate. If a rare mutation shows up in your data, there is a possibility that it is a false positive. Before acting on the information, consider doing a second, clinically accurate test to confirm. Talk with your doctor and consider your family health history and current health in deciding whether to pursue further testing to confirm a rare mutation.

Prions: Genetic mutations that increase prion disease risk
Prions are able to infect, causing the normal protein around them to also misfold. These misfolded proteins aggregate to cause neurogenerative disease. Susceptibility to prion diseases depends in part on your genes.

Alpha-1 Antitrypsin Deficiency
A genetic mutation in the SERPINA1 gene causes alpha-1 antitrypsin deficiency. This increases a person’s susceptibility to COPD (chronic obstructive pulmonary disease) and, in some cases, cirrhosis of the liver. Knowing that you carry this mutation can be a great incentive to avoid smoking and to be kind to your liver.
Cancer Prevention Strategies for Lynch Syndrome Mutations
Lynch Syndrome increases the risk of certain cancers. The cause relates to inherited mutations in the genes responsible for stopping the replication of cancerous cells. Learn how cancer occurs, risks involved with this particular syndrome, and prevention strategies to implement for risk reduction
Familial Mediterranean Fever: Mimics fibromyalgia, arthritis, inflammation
Familial Mediterranean fever (FMF) is a genetic condition of inflammatory episodes that cause painful joints, pain in the abdomen, or pain in the chest. It is most often accompanied by a fever. FMF is often misdiagnosed as various pain-related conditions such as fibromyalgia, myofascial pain syndrome, or gouty arthritis.

Pyruvate dehydrogenase is involved in the production of cellular energy in the mitochondria. People with pyruvate dehydrogenase deficiency have many health effects. Learn more about this deficiency and its genetic mutations.
Checking Your Carrier Status for Rare Genetic Diseases
The term “carrier status” when applied to a genetic disease usually means looking at whether or not you are heterozygous (have one copy) for a mutation that causes a Mendelian genetic disease. While genetic information from 23andMe or a similar DNA test is generally accurate, always re-confirm with a clinical test before making a major health decision. Your results on these variants could be a false positive or a false negative. (Member’s article)
