Poor coverage of specific gene sets in exome sequencing gives cause for concern
2014-06-01
With services based on exome sequencing becoming affordable to patients at a reasonable price, the question of the quality of the results provided has become increasingly important. The exome is the DNA sequence of genes that are translated into protein. These protein-coding regions contain most of the currently-known disease-causing genetic mutations. The American College of Medical Genetics and Genomics (ACMG) has recommended the reporting to patients of clinically actionable incidental genetic findings in the course of clinical exome testing. Specifically, mutations ...
