People affected with EDMD often have flexion contractures of the elbows and ankles. Elbow contractures force the elbow to remain bent at an angle. [mda.org.au]

[…] are the most frequent genetic cause of dilated cardiomyopathy, accounting for 6– 8% of all primary dilated cardiomyopathies and up to 40% when conduction disorders are present.17–19 LMNA mutations have been shown to be associ- ated with a very poor prognosis [dev.docslide.net]
The management is aimed more at treating the symptoms and controlling the complications (if any) The prognosis depends on the severity of the muscle contractures and the degree of cardiac involvement Emery-Dreifuss Muscular Dystrophy is a genetic disorder [dovemed.com]
Prognosis Without serious heart involvement, most people with EDMD are expected to survive at least into middle age. Slow progression of muscle involvement allows most patients to walk and work until middle age or late adult life. [mda.org.au]
Therefore, prognosis for subjects carrying or at risk of carrying D4Z4 reduced alleles h ... [5wo.tatter.us]
Etiology
The most common etiology of autosomal dominant EDMD is an LMNA gene mutation; LMNA encodes the intermediate filament protein lamins A and C, which constitute the major scaffolding protein of the inner nuclear membrane. [scholars.northwestern.edu]
(Etiology) Emery-Dreifuss Muscular Dystrophy is caused by mutations in the EMD or LMNA gene. [dovemed.com]
Both genetic and environmental factors have been implicated in BD etiology, but the biological underpinnings remain elusive. [scinapse.io]
