Fig. 3From: Dynamic monitoring of UBA1 somatic mutations in patients with relapsing polychondritisMultiple droplet digital polymerase chain reaction detected UBA1 variants in samples collected at different time points from RP patients. Samples of patient RP34 were collected at three time points for droplet digital polymerase chain reaction (ddPCR). Only the ddPCR result of the last sample revealed a fractional abundance of 1.02% of c.121T > CBack to article page
