Increasing the sensitivity of clinical exome sequencing through improved filtration strategy.

The discrepancy between the theoretical maximum and the actual clinical sensitivity of CES is primarily in the variant filtration rather than the variant capture and sequencing phase. The solution to negative CES is not necessarily in expanding the coverage but rather in devising approaches that improve variant filtration. We suggest that positional mapping is one such approach.Genet Med advance online publication 06 October 2016.
