CytoGenX Medical Genetic Laboratory Remains Open During the COVID-19 Outbreak

CytoGenX recognizes the need for rapid diagnostic testing for the at-risk pregnant population. CytoGenX understands the enormous stress that the COVID-19 outbreak places on families that are currently pregnant. CytoGenX continues to provide the fastest confirmation available of abnormal prenatal screening results from NIPT, maternal serum screening and ultrasounds. Pregnant women normally have weekly prenatal visits with their healthcare providers. However, in light of the COVID-19 outbreak, prenatal visits are being limited to lower the risk of COVID-19 exposure. This leads to screening tests also being delayed and offered only during the anatomy scan at 20 weeks gestation. Results of these tests can take up to 2 weeks to report placing enormous and often unnecessary stress on an expectant mother. If a genetic abnormality is suspected at 22 weeks gestation confirmatory diagnostic testing needs to be performed in a center that can issue those results as quickly as possible. CytoGenX can issue confirmatory results in as little as 24 hours.

The American College of Obstetricians and Gynecologists (ACOG) issued a statement that “pregnant women may be at higher risk of severe illness, morbidity, or mortality compared with the general population,” likely due to physiologic changes that happen during pregnancy, and because pregnancy constitutes “a state of relative immunosuppression as compared to non-pregnancy.” Additionally, pregnant women normally experience and increased heart rate, diminished lung capacity and are at risk for gestational diabetes all of which can lead to increased vulnerability of severe respiratory problems if infected with COVID-19. To date there is no evidence of vertical transmission (mother to fetus) of COVID-19. However, UC Berkeley researchers have shown that high fever during the first three to eight weeks of pregnancy may lead to abnormal development in the fetus specifically the heart and jaw.

Additionally, the Slone Epidemiology Center at Boston University and the CDC have reported a link to fever and neural tube defects. They report that the consumption of 400 micrograms of folic acid every day may reduce the risk of fever induced neural tube defects. The SMFM has recently released guidance regarding COVID-19 and antenatal surveillance: “Very little is known about the natural history of pregnancy after a patient recovers from COVID-19. Given how little is known about this infection, a detailed mid-trimester anatomy ultrasound examination may be considered following first-trimester maternal infection. For those experiencing illness later in pregnancy, it is reasonable to consider sonographic assessment of fetal growth in the third trimester” As these same abnormal ultrasound findings may have a genetic basis rather than a consequence of maternal hyperthermia. It is important to quickly determine if abnormal fetal anatomy has a genetic basis. A positive genetic test would allow for more accurate phenotype prediction.

It is extremely important that pregnant women have access to necessary prenatal care. The COVID-19 outbreak should not compromise the monitoring of ongoing pregnancies by the prenatal healthcare professionals. By partnering with OB/GYN and MFM practices CytoGenX strives to help maintain direct access of diagnostic genetic testing for all pregnant women. CytoGenX offers 24 hour confirmatory testing coupled with immediate access to comprehensive diagnostic testing. For more information about CytoGenX, visit them online

CytoGenX Corp. Announces the Release of Assure™ Whole-Genome Microarray

CytoGenX Corp, a leading provider of medical genetic testing services, announced today it will be offering Assure™, its new comprehensive whole-genome microarray designed to aid in the detection and identification of disease-causing genetic alterations involved in prenatal and pediatric genetic diseases as well as cancer and infertility.

CytoGenX Corp, a leading provider of medical genetic testing services, announced today it will be offering Assure™, its new comprehensive whole-genome microarray designed to aid in the detection and identification of disease-causing genetic alterations involved in prenatal and pediatric genetic diseases as well as cancer and infertility. “Assure™, is an unprecedented diagnostic-tool capable of analyzing every gene in the human genome and will serve to advance the diagnosis and treatment of countless known and unknown human diseases,” said Joseph A. Gebbia, Ph.D., founder and CEO of CytoGenX Corp.

December, 2013-The American College of Obstetrics and Gynecologists (ACOG) issued new guidelines for the utilization of chromosomal microarray (CMA) in prenatal diagnostic testing. According to these guidelines CMAshould be offered to all patients undergoing an amniocentesis or CVS and should not be restricted to women age 35 and older.

The American College of Medical Genetics (ACMG) issued revised guidelines supporting the utilization of cytogenomic microarray analysis as “first-tier” diagnostic testing for both postnatal and prenatal samples (September, 2013) and for complementing the diagnosis of neoplastic disorders (April, 2013).

The Assure™platform, offered by CytoGenX Corp., will have a profound effect on the ability to provide state of the art genetic technology to patients. Assure™ SNP array can detect complex genomic changes not apparent by either karyotype or FISH and has applications for prenatal, postnatal and oncology.CMA technology provides higher resolution than karyotyping and therefore allows genome wide screening for microdeletions and microduplications. Submicroscopic rearrangements account for as much as 15% of human genetic disease.

Assure™ whole-genome SNP microarray provided, by CytoGenX,targets the entire genome utilizing 2.67 million markers for copy number analysis, 750,000 SNP markers and 1.9 million non-polymorphic probes. The platform offers excellent performance and exceeds current guidelines for specificity and resolution across the entire genome. The high probe density provides comprehensive coverage with 100% Sanger cancer gene coverage, 100% ICCG (formerly ISCA) constitutional gene coverage, 12,000 OMIN and36,000RefSeq genes on a single array. The presence of single-nucleotide polymorphism (SNP) markers enables high-solution copy number analysis to detect gains and losses in DNA,loss of heterozygosity (LOH), regions identical-by-descent, uniparental disomy (UPD)and mosaicism.

FDA Cleared Testing at CytoGenX

CytoGenX is committed to providing the most recent advances in FDA approved genetic technologies.

AneuVysion™ (FISH): In addition to our comprehensive panel of prenatal genetic tests, CytoGenX offers the only FDA-cleared prenatal genetic test available in the United States. The DNA-based STAT prenatal genetic test (AneuVysion™) answers urgent, important questions about a fetus. Using fetal cells obtained from amniotic fluid, the test is a simple, quick and accurate way of determining if chromosomes 13, 18, 21, X and Y are present in their proper number. Together these conditions account for nearly two-thirds of all abnormalities identified at the time of amniocentesis, and 85-90% of clinically significant chromosomal abnormalities detected in live-born infants. At CytoGenX the results of this new FDA-cleared test are routinely issued in as little as 24 hours.

UroVysion™ (Bladder Cancer): CytoGenX is offering the first FDA approved gene-based test, UroVysion™ as an aid for initial diagnosis of bladder cancer in patients with Hematuria. UroVysion™ in combination with cystoscopy offers the best available combination of sensitivity and specificity in the detection of recurrent bladder cancer. This new test allows a physician and patient to now have a previously unavailable non-invasive option to accurately diagnose and manage bladder cancer recurrence.

Cystic Fibrosis: CytoGenX is now providing the new FDA approved expanded 60 mutation panel for cystic fibrosis carrier screening.  This test simultaneously screens for the 23 CFTR gene mutation/deletions recommended by ACOG/ACMG plus 37 additional mutation/deletions and 4 variants common in the ethnically diverse North American population.

PathVysion™ (HER-2/neu): CytoGenX is offering FDA approved  PathVysion™ testing which is designed to detect amplification of the HER-2/neu gene via fluorescence in situ hybridization (FISH) in formalin-fixed, paraffin-embedded human breast cancer tissue specimens.The identification of HER-2 over expression by immunohistochemistry in conjunction with gene amplification detected by FISH is associated with a comprehensive positive response to the humanized, monoclonal antibody Herceptin® in patients that have failed standard chemotherapy treatment.  The detection of HER-2 gene amplification by FISH analysis is linked with rapid cancer cell proliferation, decreased disease-free survival and poor overall survival in both node-negative and node-positive ductal breast cancers.  In patients with advanced breast carcinoma, HER-2 amplification predicts responsiveness to transtuzumab (Herceptin®) therapy and poor response to standard chemotherapy.
