How to Solve Challenging WES Cases: Atypical Positive Results
Whole Exome Sequencing (WES) is an effective diagnostic tool for patients with complex genetic disorders, but even positive test results may not always be what the healthcare provider was expecting. Occasionally, we find an atypical positive result, one that requires additional explanations and visual aids to explain to patients. What can laboratories do to detect these atypical positives? What questions and concerns might come up and how can these be addressed?
During this webinar, Senior Geneticist Kirsty Wells, PhD, and Genetic Services Consultant Rachel Goldberg, MS, CGC, will discuss recent challenging WES cases with atypical positive results and the Blueprint Genetics team’s tailored approach to tackling these. Through these examples, we explore both the clinician and interpretation team’s perspective, as well as demonstrate the power of high-quality testing that has the ability to capture the full spectrum of disease-causing genetic variation.
Patient WES Cases Include:
- An adult patient with intellectual disability, anemia, retinitis pigmentosa
- A child with bilateral radial anomalies, and negative TBX5 sequencing results at an outside lab
- A child with motor and speech delay, ADHD, joint hypermobility, and hypoplasia of the distal phalanges
- A child with global developmental delay, hypotonia, neonatal seizures, hyperlaxity, ptosis. Patient’s sibling is also affected
- Share unique cases that are less commonly found as results of whole exome sequencing
- Discuss how WES can be tailored to detect these atypical positive results
- Provide the clinician and geneticist’s interpretation perspectives when receiving and giving an atypical positive result for a patient
- Describe the importance of understanding a laboratory’s methods for interpretation of NGS data and how different methods can result in missed diagnoses
