Q: How, what methods are used to screen for health conditions that may have genetic

connections?

Answer:

Conducting Family histories

Calculating genetic risk scores GRS's

Conducting genetic counseling

Q: How, what methods are used to screen for health conditions that may have genetic

connections?

Diagnostic testing

Answer:

Diagnostic testing-If you have symptoms of a disease that may be caused by genetic changes,

sometimes called mutated genes, genetic testing can reveal if you have the suspected disorder.

For example, genetic testing may be used to confirm a diagnosis of cystic fibrosis or

Huntington's disease.

Q: How, what methods are used to screen for health conditions that may have genetic

connections?

Presymptomatic and predictive testing

Answer:

Presymptomatic and predictive testing-If you have a family history of a genetic condition,

getting genetic testing before you have symptoms may show if you're at risk of developing that

condition. For example, this type of test may be useful for identifying your risk of certain types

of colorectal cancer

Q: How, what methods are used to screen for health conditions that may have genetic

connections?

Carrier testing.

Answer:

Carrier testing- If you have a family history of a genetic disorder

— such as sickle cell anemia or cystic fibrosis — or you're in an ethnic group that has a high risk

of a specific genetic disorder, you may choose to have genetic testing before having children. An

expanded carrier screening test can detect genes associated with a wide variety of genetic

diseases and mutations and can identify if you and your partner are carriers for the same

conditions

Q: How, what methods are used to screen for health conditions that may have genetic

connections?

Pharmacogenetics.

Answer:

Pharmacogenetics- If you have a particular health condition or disease, this type of genetic

testing may help determine what medication and dosage will be most effective and beneficial for

you.

Q: How, what methods are used to screen for health conditions that may have genetic

connections? Prenatal testing.

Answer:

Prenatal testing.- If you're pregnant, tests can detect some types of abnormalities in your baby's

genes. Down syndrome and trisomy 18 syndrome are two genetic disorders that are often

screened for as part of prenatal genetic testing. Traditionally this is done looking at markers in

blood or by invasive testing such as amniocentesis

Q: How, what methods are used to screen for health conditions that may have genetic

connections? Preimplantation testing. Also called preimplantation ge- netic diagnosis

Answer:

Preimplantation testing- this test may be used when you attempt to conceive a child through in

vitro fertilization. The embryos are screened for genetic abnormalities. Embryos without

abnormalities are implanted in the uterus in hopes of achieving

Q: Family History

Answer:

Conducting an accurate family history for a min of three gener- ations can reveal a wealth of

information on which to base prevention strategies.

Q: When would family history be considered a primary intervention?

Answer:

If the information collected is used to counsel individuals on how to decrease risk with lifestyle

modifications (before the patient has the disease)

Q: When would family history be considered a secondary intervention?

Answer:

If the information should also result in screening strategies that result in the early identification

of the disease

Q: What is a genetic risk score" (GRS)

Answer:

GRSs summarize risk information from variants across the genome individuals with higher

GRSs will be more likely to develop disease

· GRS are being used to assess risks for smoking, obesity, diabetes and heart disease
