Summaries for Ehlers-Danlos Syndrome, Musculocontractural Type, 2

OMIM : 57 The musculocontractural type of Ehlers-Danlos syndrome is characterized by progressive multisystem fragility-related manifestations, including joint dislocations and deformities; skin hyperextensibility, bruisability, and fragility, with recurrent large subcutaneous hematomas; cardiac valvular, respiratory, gastrointestinal, and ophthalmologic complications; and myopathy, featuring muscle hypoplasia, muscle weakness, and an abnormal muscle fiber pattern in histology in adulthood, resulting in gross motor developmental delay (summary by Muller et al., 2013). For a discussion of genetic heterogeneity of the musculocontractural type of Ehlers-Danlos syndrome, see EDSMC1 (601776). (615539)

MalaCards based summary : Ehlers-Danlos Syndrome, Musculocontractural Type, 2, is also known as ehlers-danlos syndrome, musculocontractural type 2, and has symptoms including generalized muscle weakness An important gene associated with Ehlers-Danlos Syndrome, Musculocontractural Type, 2 is DSE (Dermatan Sulfate Epimerase). Affiliated tissues include skin, and related phenotypes are hypertelorism and frontal bossing

UniProtKB/Swiss-Prot : 74 Ehlers-Danlos syndrome, musculocontractural type 2: A form of Ehlers-Danlos syndrome characterized by progressive multisystem manifestations, including joint dislocations and deformities, skin hyperextensibility, skin bruisability and fragility with recurrent large subcutaneous hematomas, cardiac valvular, respiratory, gastrointestinal, and ophthalmologic complications. Motor developmental delay is associated with muscle hypoplasia, muscle weakness, and an abnormal muscle fiber pattern in histology in adulthood.
