DNA and de novo sequencing results of the reference patient.
Differences between the patient specific M-protein and the most homologous germline sequence are bold. Differences between the de novo sequencing result and the DNA-derived sequence are in red. No light chain DNA data was available to validate sequences obtained from de novo sequencing for the light chain. Trypsin cleavage sites are indicated with | symbols.
