Specialized Department of Genetic Counseling
In the complex world of genetics, genetic counseling serves as a vital bridge between genetic science and public health, playing an unparalleled role in the diagnosis, prevention, and management of genetic disorders. This crucial process enables individuals and families to accurately address questions regarding heredity and genetic risks, empowering them to make better decisions for their health.
Using advanced genetic knowledge and pedigree analysis, genetic counselors provide precise risk assessments and offer appropriate guidance for preventing genetic diseases. They deliver comprehensive and specialized counseling not only for the primary patient but also for family members and future generations.
On this page, we explore the importance and fundamental role of genetic counseling in maintaining health and mitigating the impact of genetic disorders, while introducing strategies for making better and more sustainable life choices.
The role of genetic counselors in maintaining family health
Genetic counselors collect personal, family, and even extended family medical histories to assess the likelihood of an individual or family members developing genetic disorders through inheritance patterns. These conditions, also referred to as genetic disorders, are caused by changes in genes. Based on this information, genetic counselors help individuals make informed decisions regarding available options, such as whether to undergo genetic testing, choose a treatment path, or select a suitable partner.
By carefully examining genetic diseases or disorders within a family, analyzing their inheritance patterns, and even addressing cases where a condition appears for the first time in a family, genetic counselors assist individuals in accurately diagnosing the probability of disease recurrence, exploring ways to prevent it, and even completely eliminating the disorder from the family lineage.
Application of genetic counseling
Genetic counseling serves as an important tool in the field of family health, enabling individuals planning marriage—especially consanguineous marriages—as well as those planning pregnancy, to understand the risks of recurrence or occurrence of hereditary and congenital disorders and acquire necessary preventive strategies. By collecting and carefully evaluating family and personal medical histories, genetic counselors can help individuals make informed decisions for their own health and the well-being of future generations.
Before conducting specialized genetic testing, genetic counseling provides families with an explanation of the benefits and limitations of such tests. This education includes the testing process, its accuracy and predictive capabilities, as well as the possible outcomes—positive or negative. This information empowers individuals to make well-informed choices about whether to proceed with genetic testing and helps them make decisions aligned with their personal and family needs.
In general, genetic counseling is a practical tool that allows individuals to more accurately assess hereditary and health-related issues. By leveraging advanced technologies, it supports them in making the best possible decisions to safeguard their own health and that of their families.
Through detailed examination of genetic diseases or disorders within a family, analysis of inheritance patterns, and even addressing conditions that appear for the first time in a family, genetic counselors assist individuals in accurately determining the probability of disease recurrence, exploring ways to prevent it, and ultimately working toward completely eliminating the disorder from the family lineage.
What does genetic counseling mean?
Genetic counseling is not just an information exchange session between you and your partner, but a specialized process provided by genetic counselors or a team of them. Any information shared or received during these sessions remains strictly confidential. More than one counseling session may be required, and depending on your specific situation, counselors may recommend certain tests.
During genetic counseling, you and your partner will gain insight into the likelihood of genetic issues or diseases that may affect fertility or your future child. This information is not definitive, and counselors may only discuss probabilities or risks related to specific concerns.
Genetic counseling does not make decisions for you but helps by providing information about test results and explaining their implications for you and your family. Even details you might hesitate to share due to embarrassment or difficulty can be important. Providing accurate and comprehensive information to the genetic counselor can assist you in making informed choices about future possibilities.
The primary goal of genetic counseling is the early identification of genetic issues and preventing their occurrence throughout your life, from before pregnancy into old age.
Before specialized genetic testing, genetic counseling explains the benefits and limitations of these tests to families. This guidance includes the testing process, its accuracy and predictability, as well as the possibilities of positive or negative results. This information empowers individuals to make well-informed decisions about whether to proceed with genetic testing, helping them align their choices with personal and family needs.

People who need genetic counseling
Genetic counseling plays a vital role in maintaining personal and family health, particularly in the following scenarios where individuals require careful assessment and evaluation of potential genetic disease risks:
When to seek genetic counseling:
۱. Pre-marital counseling: Both related and non-related couples can benefit from genetic counseling before marriage. By examining the degree of kinship and family history of hereditary and congenital disorders, genetic counselors help couples make informed decisions about their marriage.
۲. Pregnancy planning: For those with a family history of infertility, recurrent miscarriages, or stillbirths, genetic counselors can address concerns about factors that may affect the fetus and provide appropriate guidance before conception.
۳. During pregnancy: Genetic counselors review ultrasound and screening test results, recommend specific genetic tests that can be performed during pregnancy, and assist couples in making informed decisions.
۴. Child healthcare: If a child shows signs or symptoms of a potential genetic disorder, genetic counselors can help parents identify conditions such as intellectual or physical disabilities, autism spectrum disorders (ASD), vision or hearing problems, and provide appropriate solutions.
۵. Personal health management: For adults, genetic counseling is valuable in specialized areas such as cardiology, psychiatry, oncology, and more. It can assist in better managing personal health by considering family history of diseases like breast and ovarian cancer, colorectal cancer, prostate cancer, high cholesterol, muscular disorders, inherited movement disorders, and blood disorders.
Due to its significant role in safeguarding personal and family health, genetic counseling serves as a critical tool in family healthcare and the prevention of genetic and congenital diseases.

final word
Genetic counseling is a crucial and practical service offered by reputable centers such as the Future Generation Genetics Clinic. On this page, we have detailed the aspects examined in this process and the services provided to individuals.
We discussed the detection of genetic abnormalities, which can be identified from before birth through old age. Sometimes, this diagnosis can improve treatment and management decisions, revealing whether other family members might also be affected by these genetic factors or be at risk of a specific disorder.
Even if no treatment exists for a particular condition, early diagnosis can help individuals manage their expectations and seek useful support and resources.
Frequently asked questions
I am planning to marry my cousin and there is no history of genetic disease in our family. Is there a chance that our child will have a genetic disease?
Yes, even in families with no history of genetic disease, there is a chance of having a child with a genetic disease. This chance may be about 2 to 3 times that of people who are not related to you, i.e. about 5 to 7 percent of the children produced could have a genetic disease.
My wife is in her fifth week of pregnancy. Is it possible to perform a genetic test to determine paternity at this time?
The best time to perform a genetic test to determine paternity is in the 10th week of pregnancy. This test is about 99 percent accurate by examining samples of placental villi and samples of the father’s blood, hair, or fingernails.
A woman asks if she needs a genetic test to get pregnant, given that her husband has a mentally retarded cousin.
Since you and your partner are not related, it is less likely that you have a genetic predisposition to inherited mental retardation. If there is a family history of children with intellectual disabilities, it may be best for one of you to undergo full genetic testing, unless you have precise information about the genetic status of the mentally disabled family members.
Is genetic counseling necessary to identify the risk of genetic diseases during pregnancy?
Yes, genetic counseling is essential during pregnancy, especially if you or your partner have a family history of genetic disease or if you are under stress. This counseling will provide you with information about the risks associated with your genetic condition and those of your children during pregnancy.
Can I use genetic counseling to diagnose the genetic status of my children if I am not of childbearing age?
Yes, genetic counseling is also suitable for people who are seeking more accurate information about their genetic status throughout their lives. This counseling includes providing comprehensive information about the likelihood of developing genetic diseases and testing and prevention options.
