Description : The Ehlers-Danlos syndrome shows phenotypic and genetic heterogeneity; see 130000.
According to the original Beighton classification (Beighton, 1970), EDS III is the
benign hypermobility syndrome. Marked joint hyperextensibility without skeletal deformity
dominates the clinical picture. Skin manifestations are relatively inconspicuous.
Differentiation from familial joint laxity (147900) is often uncertain. Beighton et
al. (1998) reported on a revised nosology of the Ehlers-Danlos syndromes, designated
the Villefranche classification. Major and minor diagnostic criteria were defined
for each type and complemented whenever possible with laboratory findings. Six main
descriptive types were substituted for earlier types numbered with Roman numerals:
classic type (EDS I and II), hypermobility type (EDS III), vascular type (EDS IV),
kyphoscoliosis type (EDS VI), arthrochalasia type (EDS VIIA and VIIB), and dermatosparaxis
type (EDS VIIC). Six other forms were listed, including a category of 'unspecified
forms.';
