NIPT/VERAgene
OVERVIEW
WHAT IS VERAgene
VERAgene is the only non-invasive prenatal test that can simultaneously screen for aneuploidies, microdeletions and single gene diseases. The diseases screened by VERAgene are associated with moderate to severe phenotype with significant impact on the quality of life. By combining detection of aneuploidies and microdeletions with the screening of monogenic diseases, VERAgene provides a comprehensive solution to prospective parents.
HOW IT WORKS
VERAgene needs a maternal blood sample, and a buccal swab sample from the biological father. The maternal blood contains cell-free DNA from both the mother and the fetus. This cell-free DNA is isolated and analyzed along with the father’s DNA sample for any potential genetic mutations using next generation sequencing. Sophisticated bioinformatics algorithms are then used to compute the risk of the fetus having a monogenic disease.
The results are sent to the clinician who communicates them to the parents and provides the necessary counseling.

UNIQUE FEATURES OF VERAgene
VERAgene captures, counts and analyses cfDNA fragments from selected genomic regions using targeted enrichment and next generation sequencing (NGS) with proprietary genetic and analytical tools.

Targeted genomic analysis
VERAgene avoids genomic regions with complex architecture that affect test performance thereby increasing precision and accuracy

High-read depth
Captured fragments are counted several hundreds of times using NGS to achieve very high statistical accuracy and precision

Accurate fetal fraction
A proprietary bioinformatics software accurately calculates fetal fraction which increases the robustness and reliability
TYPES OF CONDITIONS DETECTED BY VERAgene
Genetic conditions are caused by unwanted changes in the genome that happen during conception. Three types of genetic conditions are detected in VERAgene:
- Aneuploidies are genetic conditions that occur when a chromosome has an extra copy (trisomy) or is missing a copy (monosomy)
- Microdeletions are genetic conditions caused by a small deletion in a specific region of a chromosome
- Single gene diseases are genetic conditions caused by mutations in a specific gene
ANEUPLOIDIES | |
CONDITION | CAUSE |
Down syndrome (Trisomy 21) | Three copies of chromosome 21 |
Edwards syndrome (Trisomy 18) | Three copies of chromosome 18 |
Patau syndrome (Trisomy 13) | Three copies of chromosome 13 |
Turner syndrome (Monosomy X) | One chromosome X |
Triple X syndrome (Trisomy X) | Three copies of chromosome X |
Klinefelter syndrome (XXY) | Extra copy of chromosome X |
Jacobs syndrome (XYY) | Extra copy of chromosome Y |
XXYY syndrome | Extra copies of chromosomes X and Y |
MICRODELETIONS | |
CONDITION | CAUSE |
DiGeorge syndrome (22q11.2) | Deletion of part of chromosome 22 |
1p36 deletion syndrome | Deletion of part of chromosome 1 |
Smith-Magenis syndrome (17p11.2) | Deletion of part of chromosome 17 |
Wolf-Hirschhorn syndrome (4p16.3) | Deletion of part of chromosome 4 |
