Clinical validity: Help
We sequenced nine positive control samples from donors. Six samples were collected from obligate carriers, potential carriers, or patients diagnosed with HA. Three samples were from VWD patients. The HA patients and carriers were known to have the pathogenic inversion in the F8 gene, which cannot be detected by NGS; … View more
