A health analytics tool for the detection of genetic polymorphisms associated with cardiovascular disease, hypertension, diabetes, insulin resistance, atrial fibrillation, stroke and dyslipidemia.
CardiaX aims to reduce the prevalence of heart disease and associated conditions by empowering patients and physicians with a vital resource for early risk detection and an enhanced focus on personalized primary prevention.
CardiaX is the largest collection of genetic mutations and serological tests that provides potential risks for heart, metabolic, and vascular conditions for individuals with the following risks:
- Family history of heart disease
- Uncontrolled hypertension
- History of cardiac events
- Diagnosed with metabolic syndrome
- Elevated inflammatory markers
- Increased medical risk for hypertension
CardiaX includes the following genetic SNPs (single nucleotide polymorphisms):
- ACE I/D
- Apo A1
- Apo A2
- Apo C3
CardiaX may be an appropriate test to run if you have or are suspected of having any of the following symptoms or conditions:
- Plaque rupture
- Coronary artery disease
- Myocardial infarction
- Diabetes mellitus
- Insulin resistance
- Venous thrombosis
- Atrial fibrillation
- Cardiovascular disease
- Congestive heart failure
- Ischemic stroke
- Endothelial dysfunction
CardiaX is the only genetic screening tool on the market that provides you with your predisposed risks based on advanced genetic markers.
Along with your CardiaX profile, you also get access to Vibrant’s Clinical Support Team of highly qualified clinical dietitians for advanced clinical interpretations and assistance in creating customized risk management plans in conjunction with your physician’s recommendations.
CardiaX can be performed from either a blood draw arranged through your medical provider or a cheek swab you can perform at home. Consult with your provider to determine which method they prefer.
When interpreting results, what does the “>” symbol signify? Example MTHFR 677 C>T?
For any gene that is Mendelian inherited, one allele is considered “wild type,” or normal (non-mutated), while a different allele is considered “mutant.” In genetic nomenclature, the “>” is used to signify which allele is wild. In the example of “MTHFR 677 C>T”, the C allele is wild/normal whereas T allele is mutated.
What do the terms homozygous and heterozygous mean in terms of these genetics?
The terms homozygous and heterozygous refer to the individual genotype or individual result and describe the extent of normalcy or mutation. There are three possible combinations for each gene:
- Homozygous wild type (no mutation; 2 copies of the normal allele)
- Heterozygous mutant (one copy of wild allele; one copy of mutated allele)
- Homozygous mutant (2 copies of a mutated allele)
Why do high risk genes on second page (summary) of the report look the same as the low risk genes towards the end of the report?
The genes observed on this report each have multiple alleles/SNPs. The overview on page 2 of the report show the alleles/SNPs that can denote the highest risks to health while the alleles/SNPs listed on page 10 towards the back of the report denote the lowest risk.
Do the genetics change once you make the recommended changes on the report?
No, genetics do not change, only expression of the genetics.
Dries DL, Victor RG, Rame JE, Cooper RS, Wu X, Zhu X, Leonard D, Ho SI, Wu Q, Post W, DraznerMH.Corin Gene Minor Allele Defined by 2 Missense Mutations Is Common in Blacks and Associated With High Blood Pressure and Hypertension.
The primary study sample was the Dallas Heart Study (DHS), a multistep probability-based sample of Dallas County residents 18 to 65 years of age which included over 3000 samples.
2 nonsynonymous, non-conservative single nucleotide polymorphisms (Q568P and T555I) were sequenced in near-complete linkage disequilibrium, thus describing a single minor I555 (P568) corin gene allele. The corin I555 (P568) allele remained independently associated with increased risk for prevalent hypertension (odds ratio, 1.63). The corin I555 (P568) allele also was associated with higher systolic blood pressure in subjects not using antihypertensive medication in unadjusted (133.7 ± 20.7 versus 129.4 ± 17.4 mm Hg) and adjusted (132.5 ± 1.6 versus 128.9 ± 0.6 mm Hg) analyses.
