Can Ancestry DNA Find Health Issues?

Can Ancestry DNA Find Health Issues?

21 October 2022

A DNA testing might shed light on your current state of health. Anyone can now acquire a wide range of genetic testing in clinical and consumer settings. These tests are available to people. Through a mouth swab, a sample of hair, or a blood test, people, as well as medical professionals and scientists, can check a person’s DNA in search of alterations (mutations) associated with specific characteristics or diseases. You may find out whether your DNA has a mutation for a genetic illness that might affect your unborn child by taking a test called a carrier test.

In the end, people who seem healthy might have anomalies in their DNA connected to certain hereditary disorders. If someone has inherited a single copy of the gene mutation that leads to an inherited condition or illness, this indicates that they are a carrier for that condition. Because the individual’s DNA still has an extra copy of the same gene, unaffected by the mutation, the state does not impact the person’s health. 

The Diagnosis of an Inherited Illness

Medical professionals often use genetic testing to validate a genetic ailment diagnosis in patients with specific symptoms. Ancestry DNA testing has several benefits, one of which is that it enables medical professionals to uncover hereditary illnesses at any age.

This is particularly helpful for those with conditions like familial hyperlipidemia, which may result in heart attacks and strokes at an earlier age. Patients with cardiac issues diagnosed early (i.e., before their first heart attack) can potentially have additional treatment options.

Testing for Genetic Conditions Before Symptoms Appear

Medical professionals may then analyze the information to establish whether or not the patient is at risk of developing the condition. However, determining a person’s likelihood of developing a disease caused by many mutations in a single or a small number of genes is more complicated. Genetic testing is helpful because it enables medical professionals to investigate various gene variations. This may give them an idea of whether a person will get unwell, how severe the ailment will be, and even treatment possibilities.

DNA Testing with Predictive Capabilities


A DNA test may screen for a mutation in the BRCA 1/BRCA 2 gene, which is well-known for being associated with an increased risk of developing cancer. On the other hand, it is essential to remember that genetic alterations are not the root cause of every kind of cancer. Several cancer-causing mutations are sporadic, meaning they happen randomly and at unexpected periods due to environmental factors. Because of this, the results of a genetic test cannot reliably indicate whether or not a person will get cancer.

Using a person’s genetic makeup to determine whether or not they will develop a disease is a laborious and challenging process. In a clinical setting, such as a doctor’s office, testing may look for different things than a DNA test that you purchase from the shop would look for on its own. Using these tests, you may typically learn whether or not your DNA has undergone alterations that increase the likelihood that you will acquire a disease or condition.

SNP Test Results

Some types of 24-hour DNA testing may determine whether or not you are more likely to have features such as lactose intolerance or a more significant overall body weight. Numerous Ancestry DNA tests kits available to the general public these days provide results that are irrelevant to the question of whether or not a person has a major hereditary problem.

Problems of an Existential and Psychological Kind

According to studies on mental health, significant and unexpected shocks can create a great deal of emotional turmoil. As a result, being aware of previously unknown facts about one’s family dynamics can bring significant psychological and existential challenges for both people and their families.

The revelation of shocking information about parentage, particularly when the paternity of a child is incorrectly assigned, can disrupt the social ecology that already exists within families, which may result in existential pain and conflict within the family. Similarly, matching with previously unknown biological parents and children may provide significant challenges for people, including: Should I get in touch with them? Should I get in touch with them? Should I establish a romantic connection with someone?

Because there is neither a rule book nor a standard operating process, it is only natural that every person startled by DNA testing would have their responses to these queries. Discovering the truth and contacting biological relatives may be a pleasant experience, forming new families and friendships for some.

Helping Those Who Are Surprised

People who have been startled by the results of DNA testing have been able to interact with one another and form self-help groups, both online and in person, thanks to social media. The Not Parent Expected (NPE) Friends Fellowship is the most prominent of these, and it is a group founded by and for individuals astonished by such outcomes. This organization offers Facebook groups in addition to meet-up groups in significant cities; both types of groups give support and consolation to members.
