From Our Advocates

Based on our experience helping patients navigate Onpattro approvals, the most common stumbling block is incomplete genetic testing documentation. Many patients have older genetic reports that don't clearly identify the specific pathogenic variant. Getting an updated, comprehensive genetic report from a CLIA-certified lab often resolves denials quickly and prevents lengthy appeals.
