CHOP researchers use “deep sequencing” to identify several previously undescribed genetic variants in vascular anomalies

June 13, 2023
The study captured genetic variants at extremely low levels, and dozens of patients began new therapies as a result of the findings.

Researchers from Children’s Hospital of Philadelphia (CHOP) recently discovered that extremely thorough “deep sequencing” of the genome in tissue samples and cell-free DNA of patients with potentially life-threatening vascular anomalies captured several genetic variants related to disease that were not captured with conventional genetic sequencing methods.  

More than 60% of patients saw an improvement in their condition after being placed on targeted therapies related to these newly found genetic variants. The findings were published in the journal Nature Medicine.
