ADAMTS2 and Ehlers-Danlos syndrome, dermatosparaxis type: In order to clarify why arthrochalasia and dermatosparaxis EDS display different clinical phenotypes (Van Damme et al., 2016) and to investigate the diverse functions of ADAMTS2 and ADAMTS14 in vivo (Dupont et al., 2018), N-Tails analysis has been performed on skin samples from wild-type mice (Wt) and TS2−/−, TS14−/− and TS2−/−TS14−/−.
