GeneDx to Highlight Key Research Findings at American Society of Human Genetics (ASHG) Annual Meeting
Data to be presented showcasing
Research to be presented this week at ASHG will include:
Rapid whole genome sequencing (rWGS) in the NICU leads to changes in clinical care:
- In collaboration with SeqFirst, patient cases were analyzed when a diagnosis was found with rWGS to understand how decisions were made with genomic sequencing and what is missed in its absence when only using conventional care protocols.
Racial disparities in an accurate genetic diagnosis:
-
In one of the largest studies to look at ancestral backgrounds and genetic diagnosis, GeneDx, the
University of Washington , and Geisinger explore the value of a diverse dataset to understand diagnostic yield and if it varies significantly based on ancestral background or if other factors are limiting access to a genetic diagnosis.
Data validation for long read sequencing:
- With growing interest in the field to explore the clinical utility of long read sequencing, validation data will be presented assessing the sensitivity of PacBio’s HiFi long read sequencing to detect cases with a confirmed answer on short read whole genome sequencing (WGS) Additional cases where long read sequencing uncovered pathogenic variants that were difficult to detect on short read WGS will be presented.
Genetic variants linked to Autism Spectrum Disorder (ASD):
-
Working alongside the
Autism Sequencing Consortium , research identifies 230 new genes associated with ASD. This molecular evidence underscores the effectiveness and accuracy of genetic diagnostics compared to current methods, which rely on parents’ or caregivers’ accounts of their child's development or professional observations of behavior.
“The opportunity to present these findings at ASHG underscores GeneDx’s commitment to advancing genomic research to move forward its application in clinical settings,” said Dr.
