Genetic Counseling For Cystic Fibrosis

Genetic Counseling for Cystic Fibrosis

Some of the inherited genes may predispose individuals to certain health conditions like cystic fibrosis among other inheritable diseases. Therefore, genetic counseling is recommended for people with a family history of a certain inheritable condition. This paper discusses the reasons for genetic counseling and possible responses from a patient together with ways of avoiding negative reactions.

Reasons for Genetic Counseling

The main reason for a genetic counseling exercise is to assess the risk of developing a certain health condition or disorder based on one’s genetic patterns. Additionally , during this exercise, causes and inheritance of the disorder in question are explored together with establishing the availability of testing, prognosis, treatment, and medical management. Therefore , anyone with a family history of a given heritable condition can undergo this form of counseling. Similarly, one can undergo screening for conditions that are common within a certain ethnic group. Genetic screening can be carried out to establish whether there are familial causes behind developmental or health problems. Genetic counseling for cystic fibrosis is common to people planning to have a child. Based on the available information, parents are advised about the risk of having a child with this condition.

Possible Reactions from the Patient

In most cases, when people find out that they are predisposed to cystic fibrosis, they become anxious. Some may react calmly, process the information, and cooperate in charting the way forward. However, other people may react negatively and slip into denial. Therefore, the involved health practitioner should be keen on finding ways to handle the counseling session. To avoid negative reactions, one should communicate professionally by conveying information without sounding as an alarmist. Patients should be informed about the availability of different management and treatment methods for the condition.



Since cystic fibrosis is a genetic disorder, the only way to prevent it is to ensure couples seeking to have children are not carriers of the recessive gene. However, there is no guarantee that a child will not have the condition, as the gene is large and complex. Therefore, some of the genetic mutations associated with cystic fibrosis have not been discovered.


Anyone with a family good cystic fibrosis should undergo testing. Additionally , couples preparing to possess a youngster should be examined for this issue. Screening of cystic fibrosis occurs via DNA testing in order to establish the existence of veränderung of the cystic fibrosis transmembrane conductance regulator (CFTR) (Cutting, 2015). The perspire test is the particular popular screening process. In this procedure, perspiration is obtained through the patient as well as the amount of chloride inside it is tested. Based on the results from the particular sweat test, additional tests can end up being conducted using bloodstream samples to set up DNA mutations that will are specific in order to this condition. The objective of screening is in order to generate data that will can be utilized in diagnosis.


After the particular involved physician will get laboratory results, analysis is made utilizing the availed data. Within the sweat test, when the chloride level is usually ≤ 29 mmol/L, the probability of getting the condition will be ruled out. However, with regard to levels between 30-59 mmol/L, one offers a chance of getting cystic fibrosis, as well as the results are repetitive. Finally, for amounts ≥ 60 mmol/L, the first is highly probably to be identified as having the condition. Inside DNA testing, in case persons have 1 copy of CFTR gene mutation, these people do not experience from the problem, yet they are service providers. Nevertheless , if a good individual has 2 copies of variations, he or the girl is classified while having cystic fibrosis.


Within cases where 2 carriers have the child, she or he can have a 25 percent odds of having cystic fibrosis and 50 % probability of getting a carrier (Massie, Johnson, & Cooper, 2016). Nevertheless , there will certainly also be the 25 percent prospect that this child will certainly not have the problem or be the carrier. If 1 of the companions has cystic fibrosis and the some other is actually a carrier, presently there is a 50-50 chance that the particular child will have got the condition or even become a provider (Massie et ing., 2016). Finally, in case one partner will be a carrier plus the other the first is not, the possibility of the kid getting the condition will be minimal.

Choice of Treatment

Currently, presently there is no recognized cure for cystic fibrosis. Therefore, the particular available treatments are accustomed to ease symptoms and reduce complications. Antibiotics may be used to prevent and deal with different lung bacterial infections (Edmondson & Davies, 2016). Additionally, anti-inflammatory drugs may become used to decrease swellings in the particular lungs and air passage. Mucus thinning medicines help to improve lung functionality. Bronchodilators relax bronchial tubes muscles in order to maintain open air passage. Oral pancreatic digestive enzymes may be utilized to help in the particular absorption of nutrition in the digestive system (Edmondson & Davies, 2016). Moreover, upper body physical therapy may be used rather than medications. Ultimately, surgical treatment may be utilized to remove nose polyps, which impact breathing. The determined treatment depends upon the diagnosis.

Monitoring associated with Treatment Effectiveness

The checking of the usefulness from the chosen therapy plan occurs via the assessment from the outcomes observed in different stages from the procedure. If the certain treatment will be not working or even delivering desirable effects, alternatives are regarded as underneath the instructions associated with a qualified healthcare practitioner.


Cystic fibrosis is really a genetic condition, and individuals undergo genetic guidance to establish the particular risk of getting the disorder. During the particular counseling session, problems like prevention, testing, diagnosis, prognosis, healthcare management, and therapy are addressed. This particular form of guidance is important as it may allow couples to create informed family arranging decisions.
