The impact of family history on your genetic health

How family history affects your genetic health

The family history Genetic factors have always had a certain importance in genetic health. This could previously be seen with the naked eye in the phenotype. But in recent years, with advances in genetic research, it has also been possible to refine the definition of cause-and-effect relationships much more precisely. These are the main cases you may encounter, including risks and diseases:

1. Risks of genetic predisposition to suffer from diseases

Risk factors are one of the main factors associated with genetic inheritance. Certain markers indicate genetic mutations that make a person more prone to genetic diseases . Let's give some examples of hereditary probabilities:

  • Cancer: There are some varieties of cancer such as breast or ovaries which are more common in women who have alterations in the BRCA1 or BRCA2 gene. On the other hand, we can also find this predisposition in the prostate cancer , specifically in the BRCA2 and HOXB13 variables. A common case is that of skin cancer , through the CDKN2A gene. Finally, it should be noted that the colorectal, thyroid or pancreatic cancer have genetic mutations that influence.
  • Obesity: Obesity is a multifactorial problem that has numerous implications. However, there are some mutations that have a 6% chance to develop childhood obesity . It is therefore important to take this into account when diagnosing these problems.
  • Lung diseases: Lung diseases have a genetic influence. For example, the relationship with the asthma and certain chronic pulmonary obstructions . This also requires consideration of whether other factors may be involved.
  • Mental disorders: some mental illnesses such as schizophrenia could be related to certain genetic alterations. However, it must be said that the search field is still very broad. Likewise, there are other ailments that could be related.
  • Neurodegenerative diseases: It is still under investigation, but certain diseases, such as Alzheimer's, could be related to mutations in the APOE-ε4 gene. Although we are in the realm of speculation, it is estimated that up to 20% could have a correlation.

Consequently, genetics plays a significant role in certain diseases. What we're talking about here is risk factors, which aren't necessarily determinants in all cases. Hence, having this data is useful for decision-making.

2. Genetic health: congenital diseases

In some cases, there are congenital diseases that have a direct and proven correlation with family history. The most common ones, which influence genetic health, are the following:

  • Cystic fibrosis : This hereditary disease is caused by a genetic alteration and causes a variety of problems, from respiratory problems to the liver and excretory system. The main problem is excess mucus, and if there is a family history of it, special caution is needed.
  • Hypercholesterolemia: Hypercholesterolemia is another condition with a hereditary genetic component. Obviously, this abnormal increase in cholesterol, caused by genetics, can lead to problems associated with cardiovascular disease. What's more, when it comes to this, it's not necessary to have associated obesity problems.
  • Marfan syndrome: It is considered a rare disease because its incidence is less than 1 case in every 2,000 people. It is hereditary and occurs due to alterations in the FBN1 gene . Obviously, if there is a family history (paternal or maternal), we recommend seeking information as soon as possible to rule it out.
  • Hemophilia: It is primarily transmitted to males through the mother, as this occurs through alterations in the X chromosome. If there is a family history of this problem, such as uncles, we have a clue. It is a relatively easy disease to detect, precisely because the symptoms are very evident from childhood.
Many of these diseases appear immediately after birth and are quickly diagnosed with a heel prick test. Therefore, when considering reproductive options , this factor should not be overlooked.

What measures should be taken in this regard?

To know what the Family history , in relation to genetic health, we recommend you follow these steps. Take note, you'll be interested:

  • Gathering information: The first thing to do is gather all the information you have about your direct and collateral ancestors. This is crucial because you may not have a parent or grandparent with problems, but you do have aunts, uncles, cousins, and siblings. These collateral branches can provide information about predispositions. If you need to review death certificates and the causes of death, now is the time to do so.
  • Genetic testing: Whenever you have a suspicion, it's a good idea to get a genetic test. For example, there's a genetic panel to rule out various conditions if you suspect one. There's also a carrier test. And finally, for couples, a genetic compatibility test is very useful to determine if the offspring have potential risks.
  • Change of lifestyle habits: Changing lifestyle habits, if they are harmful, is highly recommended to reduce the risk of getting sick. Quitting smoking and alcohol, exercising, maintaining a healthy diet, or avoiding pollution are some examples. It's worth keeping in mind. In the end, since we're talking about risk factors, changing habits can reduce that risk.
  • Frequent reviews: If you have a genetic predisposition to diseases, it's a good idea to get frequent checkups. We all need them from time to time, but it's no secret that, in your case, you'll need to go a little more often. This way, you'll better control the associated risks.

Consequently, all of these factors influence early detection, treatment, and problem avoidance. This is even more important when we're talking about susceptibility rather than congenital diseases.

Therefore…

Genetic health is closely linked to heredity and our ancestry. Therefore, anything that helps you gain more information will help you. Genotics You'll find numerous genetic tests to see what genetic markers you've inherited and monitor potential risks. Get to know us better!
