Clinical Genetics. BACKGROUND AND PURPOSE: Single-gene disorders are included in the differential for nonimmune hydrops fetalis (NIHF) Sparks et al. ES enabled the molecular diagnosis/classification of patients with EOS. In this cross-sectional study that included 2 independent cohorts of 1526 patients with cerebral palsy, the molecular diagnostic yield of exome sequencing was 32.7% in a cohort that predominantly consisted of pediatric patients and 10.5% in a cohort that predominantly consisted of adult patients. As test costs decline, whole-exome sequencing (WES) has become increasingly used for clinical diagnosis, and now represents the primary alternative to gene panel testing for patients with a suspected genetic disorder. We performed exome-based read-depth CNV screening on data from 2,603 patients affected by a range of genetic disorders for which exome sequencing was performed in a diagnostic setting. What is the molecular diagnostic yield of exome sequencing (prevalence of pathogenic and likely pathogenic variants) among patients with cerebral palsy? Using WES read depth data to predict copy number variation (CNV) could extend the diagnostic utility of this previously underutilized data by providing clinically important information such as previously unsuspected deletions or duplications.
