Villefranche nosology consolidates to six types
eventevidence: established
Beighton et al. published the revised Villefranche nosology (1997, printed 1998), consolidating EDS into six major types: classical (I/II), hypermobility (III), vascular (IV), kyphoscoliosis (VI), arthrochalasia (VIIA/B), and dermatosparaxis (VIIC). The revision aligned clinical types with the emerging molecular era.
