GeneDx has launched a prenatal Noonan syndrome spectrum test that runs on Illumina's MiSeq, taking advantage of the platform's short turnaround time, and is planning additional prenatal next-gen sequencing panels. Also, the company recently released an expanded version of its diagnostic whole-exome sequencing test that includes the mitochondrial genome and plans to offer a focused version of the test that only analyzes a small subset of the genes.
