DNA-based NGS

Advantages

The advantages of DNA-based NGS are those common to all NGS techniques as well as those specific to the DNA-based NGS. The advantages of DNA-based NGS are summarised in the following table.

Advantages of DNA-based NGS for Testing for NTRK Gene Fusions

Advantages
Assesses molecular information such as mutations, copy number changes, and microsatellite instability status with high resolution [1, 2]. Detects rearrangements in multiple genes and introns [3, 4]. Can identify translocation partners without direct targeting of these partners [2].
