Sequencing is performed at an average coverage of at least 100x, aiming at a minimum coverage of 15x per base (vertical coverage >15x) for at least 98% of the coding sequence and flanking intron-exon boundaries (horizontal coverage >98%). The test is greater than 99% sensitive for detecting substitution variants in …
