Cardiogenetic testing: when CVD risk is hereditary
In many patients, the risk of cardiovascular disease (CVD) may be attributed to genetic polymorphisms and mutations.1 Quest Diagnostics offers cardiogenetic testing to aid in early diagnosis and earlier treatment for affected patients, as well as family members.
Familial hypercholesterolemia (FH) refers to a group of genetic defects resulting in severe elevations of blood cholesterol levels and increased risk of premature coronary heart disease (CHD). These defects are found in the FH genes, LDL receptor (LDLR), apolipoprotein B (ApoB), proprotein convertase subtilisin/kexin type 9 (PCSK9), and possibly others.
Today, FH is generally underdiagnosed and undertreated. With the help of genetic testing, you can change that trend. Cardio IQ® genetic testing for FH from Quest detects mutations on the LDLR, ApoB, and PCSK9 genes to enable an early, specific diagnosis of FH.

Cardio IQ® cardiogenetic testing helps provide deeper insight into genetic risk of CVD as well as therapy selection.
Cardio IQ® cardiogenetic testing from Quest
|Test name||Clinical utility|
|Cardio IQ® 4q25 AF |
|Aids in the assessment of risk of atrial fibrillation and cardioembolic stroke|
|Cardio IQ® 9p21 Genotype||Aids in the assessment of risk associated with myocardial infarction (MI), especially before age 50 in males and age 60 in females|
|Cardio IQ® Apolipoprotein |
E (ApoE) Genotype
|Helps determine the subtypes of ApoE which will aid in the risk assessment of coronary heart disease (CHD) and hyperlipoproteinemia|
|Cardio IQ® CYP2C19 |
|Helps assess likelihood of reduced or enhanced clopidogrel response. Guides treatment strategy for patients being considered for, or receiving, antiplatelet therapy|
|Cardio IQ® KIF6 Genotype||Helps detect a gene variant associated with CHD risk and such CHD events as may be reduced from statin therapy|
|Cardio IQ® LPA |
|Helps identify individuals who are at risk of having elevated plasma lipoprotein (a) [Lp (a)] and increased cardiovascular risk which could be reduced by low-dose aspirin therapy|
|Cardio IQ® LPA |
|Helps identify individuals at risk for elevated plasma lipoprotein (a) [Lp (a)] and increased cardiovascular risk|
