Clinical genetics provides assessment and counseling for genetic or hereditary diseases. Consultations are personalized and based on complete medical analysis.
Clinical genetics deals with the assessment, diagnosis and counseling in the case of genetic diseases or the risk of hereditary transmission. In this specialty, geneticists and genetic counselors work together to understand whether there is a genetic condition, what the risk is for the patient or family, and what testing or monitoring options are appropriate. Clinical genetics services provide not only diagnosis and risk assessment, but also support for understanding outcomes and their medical and family implications.
Clinical genetics consultation is recommended when there are cases of genetic diseases in the family, suspicion of genetic syndrome, abnormal results in other investigations, repeated miscarriages, infertility in certain contexts, or when genetic risk assessment is desired before conception or during pregnancy. Carrier screening is considered useful before pregnancy or during pregnancy to estimate the risk of having a baby with certain genetic diseases.
Clinical Genetics Consultation
Assessment of personal and family history
Assessment of hereditary risk and recommendation of appropriate tests
Genetic counseling before and after testing
Interpretation of the results and orientation of the next steps
Clinical genetics has an important role both in diagnosing some conditions and in prevention and reproductive planning. Sometimes genetic testing is recommended to clarify a diagnosis, sometimes to assess the risk of passing on a genetic disease or to guide monitoring and medical care. The NHS shows that genetic and genomic testing can be used to confirm or rule out a diagnosis, assess family risk and support care-related decisions.
For a correct assessment, it is important to follow some essential steps:
Let's analyze personal and family history as completely as possible.
Let's understand what type of test is recommended and why.
Let's differentiate between screening and diagnosis.
Let's interpret the result together with the doctor or genetic counselor.
Let's discuss the medical and family implications of the result.
1.An essential aspect in clinical genetics is the difference between screening and diagnosis. MedlinePlus explains that screening tests estimate whether the risk for a particular condition is higher or lower than average, while diagnostic tests are used to identify or confirm a genetic condition. That means that a positive screening result is not automatically equivalent to a definite diagnosis.
2.Genetic counseling is a central part of the process. Genetic counselors and specialized physicians help the patient understand genomic risk, the meaning of testing, possible outcomes, and options available after testing. This is especially important in the reproductive, prenatal context, or when the outcome may also have implications for other family members.
Among the situations commonly evaluated in clinical genetics are:
family history of genetic diseases or hereditary cancer,
suspicion of a genetic disease in a child or adult,
carrier screening before pregnancy,
abnormal results in prenatal tests,
interpretation of genetic tests already carried out.
3.Genetic testing can bring important benefits, but it also has limits. MedlinePlus shows that results can help reduce uncertainty and make informed decisions, but sometimes they can be inconclusive or provide limited information about the severity, evolution, or timing of a disease. In other words, a genetic test does not always fully answer all clinical questions.
4.There are also emotional and family aspects to consider. MedlinePlus notes that genetic testing can generate anxiety, guilt, family tensions, or questions about other family members, precisely because the results may suggest relevant information for relatives as well. For this reason, the pre-test and post-test discussion is very important.
5.In the reproductive context, ACOG recommends that carrier screening be offered before or during pregnancy, and counseling clearly explains what the test can and cannot show. Also in prenatal, ACOG emphasizes that several screening methods should not be overlapped simultaneously without a clear strategy, but a coherent and correctly interpreted approach must be chosen.
We ask ourselves the question of a clinical genetic evaluation when there are signs that suggest a hereditary disease, when there are several similar cases in the family, when there is a need to clarify a reproductive risk, or when the results of some genetic tests need to be interpreted correctly. In many situations, consultation is valuable not only for recommending the right test, but also for deciding whether testing is really useful at that time.
At CMIB, we approach clinical genetics through a careful, clear and personalized assessment, geared toward understanding genetic risk and choosing the most appropriate testing and counseling options. Schedule a consultation and find out what genetic investigations are recommended in your case.
Clinical genetics is the medical specialty that deals with diagnosing genetic diseases, assessing hereditary risk, and counseling patients and families about genetic testing and its implications.
The consultation is useful if there are genetic diseases in the family, suspicion of genetic syndrome, abnormal prenatal outcomes, fertility questions or repeated miscarriages, or if you want to understand genetic risk before conception.
No. Genetic testing is the analysis itself, and genetic counseling is the specialized discussion that helps to choose the right test and interpret the result.
No. Sometimes the results may be inconclusive or provide limited information about the severity of the disease, its course, or when symptoms might appear.
