Preferred Label : Ehlers-danlos syndrome, arthrochalasia type, 1;

Symbol : EDSARTH1;

CISMeF acronym : EDSARTH1; EDS7A;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Eds viia; Ehlers-danlos syndrome, type viia, autosomal dominant; Eds VII, mutant procollagen type; Arthrochalasis multiplex congenita; EDS7A;

Description : EDS type VII is distinguished from the other types of EDS by the frequency of congenital hip dislocation and extreme joint laxity with recurrent joint subluxations and minimal skin involvement (Byers et al., 1997; Giunta et al., 2008). 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.';

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the collagen I, alpha-1 polypeptide gene (COL1A1, 120150.0026);

Prefixed ID : #130060;
