HOUSTON, TX (October 2, 2023), Baylor Genetics, a clinical diagnostic laboratory at the forefront of genetic testing, today announced its scientists and genetic counselors will present 10 research abstracts at three major upcoming conferences, including the National Organization for Rare Disorders (NORD) Breakthrough Summit, National Society of Genetic Counselors (NSGC) Annual Conference, and the American Society of Human Genetics (ASHG) Annual Meeting.
“With our ongoing focus on scientific publications and presentations, Baylor Genetics continues to conduct and share meaningful research findings drawn from our collaboration with the Baylor College of Medicine and other partners so that we can advance the field of genetics and provide better answers for the patients and providers who rely on us,” said Christine Eng, M.D, Chief Medical Officer and Chief Quality Officer at Baylor Genetics. “These annual meetings are an important opportunity for researchers, clinicians, and lab professionals to come together with care teams to exchange knowledge and data that represent the latest insights in genetic testing and personalized care.”
NORD Breakthrough Summit, October 15-17, Washington, D.C.
The NORD Rare Diseases and Orphan Products Breakthrough Summit brings together more than 900 advocates, experts, and stakeholders to tackle pressing issues facing the rare disease community. Robert Rigobello, Manager of Medical Affairs at Baylor Genetics will present two accepted abstracts:
- “ACMG Secondary Findings: A Review of Patient Choices in Reporting”
- Summary: Baylor Genetics reviewed internal data, ordering and reporting practices for secondary findings on Whole Exome Sequencing (WES) and Whole Genome Sequencing (WGS) tests from 15 US-based laboratories. Researchers found that despite guidance from the American College of Medical Genetics and Genomics (ACMG), there are inconsistencies in families’ selection for reporting secondary findings and significant variation in reporting practices among surveyed laboratories. The authors recommended consistent practice would be beneficial to providers and families.
- “A Case Report: BCOR-related Congenital Hypertrophy of the Retinal Pigment Epithelium”
- Summary: Whole exome sequencing revealed a variant in the BCOR gene, which led to a diagnosis of X-linked Microphthalmia, syndromic 2, a spectrum disorder which includes oculofaciocardiodental (OFCD) syndrome on a patient with multisystemic findings, including congenital hypertrophy of the retinal pigment epithelium (CHRPE). BCOR-associated CHRPE has only been reported a few times in literature, but cases suggest BCOR testing should be considered for patients with CHRPE who have additional findings consistent with a congenital anomaly syndrome.
NSGC Annual Conference, October 17-21, Chicago
The National Society of Genetic Counselors Annual Conferenceshowcases advancements across the genetic counseling profession, to share knowledge of clinical and scientific best practices and insights into emerging research. Christina Settler, Vice President, Medical Affairs, and Carli Andrews, Medical Science Liaison at Baylor Genetics will present findings from three accepted abstracts.
- “ACMG Secondary Findings: A Review of Patient Choices in Reporting”
- Baylor Genetics reviewed internal data, ordering and reporting practices for secondary findings on WES and WGS tests from 15 US-based laboratories. Researchers found that despite guidance from ACMG, there are inconsistencies in families’ selection for reporting secondary findings and significant variation in reporting practices among the surveyed laboratories. The authors recommended consistent practice would be beneficial to providers and families.
- “When Symptoms Don’t Make Sense: The Power of Diagnostic Tools for Identifying Dual Diagnoses”
- Summary: Researchers performed a retroactive study of patients who had concurrent WES and chromosomal microarray analysis (CMA) tests ordered between 2018-2022. Fifteen patients had a dual diagnosis. For most (10), WES and CMA provided distinct diagnoses.
- “ACMG Secondary Findings: A Reporting Dilemma”
- Summary: Baylor Genetics reviewed the practices when returning secondary findings on WES and WGS tests from 15 US-based laboratories. These findings indicate there is no consistent reporting process for secondary findings on WES/WGS with 8 out of 15 labs issuing individual parental reports separate from the proband report. The practice of charging for additional reports and reporting of additional findings aside from secondary findings varied among the labs reviewed as well.
ASHG Annual Meeting, November 1-5, Washington, D.C.
The American Society of Human Genetics’ Annual Meetingbrings together more than 8,000 scientists to discuss advances in the field. Baylor Genetics experts had five abstracts accepted for the annual event. These will be presented by Qin Sun, Ph.D., Senior Division Director of Biochemical Genetics at Baylor Genetics; Hongzheng Dai, Ph.D., Associate Clinical Director NGS/Molecular, Baylor Genetics; Matthew Chau, Fellow, Clinical Genomics, Baylor Genetics; Weimin Bi, Ph.D., Division Director, Cytogenetics, Baylor Genetics, and Janice Smith, Ph.D., Senior Clinical Director, Cytogenetics, Baylor Genetics.
- “Advancing Tay-Sachs Disease Carrier Screening: Insights from Combined Enzyme and Molecular Approaches”
- Summary: Researchers conducted a retrospective analysis of Tay Sachs disease carrier test results from the Baylor Genetics laboratory database. Findings highlight the potential value of including molecular testing for HEXA in carrier screening in combination with Hex A enzyme analysis.
- “Advancing Precision Diagnosis through Simultaneous Detection of Diverse Variant Types: Insights from Clinical Whole Genome Sequencing”
- Summary: Whole Genome Sequencing (WGS) offers healthcare providers the ability to test for many types of variants with one assay. This abstract summarizes the experience performing clinical WGS at Baylor Genetics to highlight its utility as a first-tier diagnostic test capable of detecting a spectrum of variant types. The review found up to 30% of patients with a diagnostic WGS finding related to phenotype would not have been captured by assays only focusing on SNV/indels.
- “Not Just One: The Utility of Whole Genome Sequencing for Making a Dual Molecular Diagnosis”
- Summary: Whole genome sequencing (WGS) offers a comprehensive solution for genetic investigation by capturing a wide range of genomic variations in a single test. Researchers performed a retrospective evaluation of WGS results at Baylor Genetics to look for multiple reportable molecular findings. Reportable multilocus findings were detected in 48 cases.
- “Prenatal CMA Using Exon-Level Coverage for 'Disease Gene' CNV Interrogations in the Era of Non-Invasive Prenatal Testing”
- Summary: This study investigated the role of prenatal chromosomal microarray analysis (CMA) in the era of non-invasive prenatal testing (NIPT) over the last 11 years at Baylor Genetics. Researchers found prenatal CMA remains essential for the detection of microdeletions/duplications because NIPT is limited in screening for submicroscopic copy number changes, and a diagnostic test such as CMA in follow up to NIPT results that are positive or at increased risk is important.
- “Products of Conception Analysis by Chromosomal Microarray: A Single Center Experience”
- Summary: Researchers reviewed data of products of conception (POC) via conventional chromosome analysis or chromosomal microarray (CMA). The data show CMA has an advantage over conventional chromosome analysis.
