An approach to pediatric exome and genome sequencing

Current Opinion in Pediatrics
L G Biesecker, B B Biesecker

Abstract

Exome and genome sequencing have recently emerged as clinical tools to resolve undiagnosed genetic conditions. Protocols are critically needed to identify proper patients for testing, select a test and laboratory, engage parents in shared decision-making, and for the return of results. Among well selected patients, the likelihood for identifying the causative gene change may be as high as 30%. It is key for pediatricians to consider whether sequencing should be the primary line of pursuit of a molecular diagnosis. Parents should understand the uncertainties inherent in this sequencing and the preference-based nature of testing. Pediatricians can engage in shared decision-making for this process and work to help parents make decisions consistent with their priorities and values. Upon receipt of a pathogenic mutation, discussion of the likelihood for future treatment is paramount to parents, as are the implications for recurrence within the family. Uncertainties inherent to genomic results need to be explained in the context of the likelihood of future research and discoveries. Pediatricians should make a deliberate decision with each patient whether to manage genomic testing on their own, refer the patient for such testing, or i...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.
