Genetic variants that cause rare disorders may remain elusive even after expansive testing, such as exome sequencing. The diagnostic yield of genome sequencing, particularly after a negative ...

Copy number variations (CNVs) are a pervasive form of genomic variation that entail duplications or deletions of DNA segments ranging from kilobases to megabases. In animal genomes, CNVs contribute ...

"Our study demonstrates that incorporating copy number variant analysis into exome sequencing workflows increases diagnostic yield in diverse pediatric cohorts," Dr. Ji explains. This approach ...

New research finds one copy of a protective genetic variant, APOE3 Christchurch, delayed onset of Alzheimer's disease for 27 members of a ~6,000-person family in Colombia at high risk for early-onset ...
