Presentation
Affected children may present with delay or arrest of gross motor development together with joint and/or spinal rigidity. [ncbi.nlm.nih.gov]
We present the evolution of cardiac disease in three children with congenital muscular dystrophy presentation of LMNA -related muscular dystrophy. In this series, atrial arrhythmia was the presenting cardiac finding in all three patients. [cambridge.org]
They play an important role in the organization of chromatin and nuclear membrane. [2] Diagnosis [ edit ] Unlike most muscular dystrophies, lamin A/C CMD does not present a breakdown of muscular fibres caused by muscle degeneration. [en.wikipedia.org]

Treatment
Said one parent of an affected child, “I'm very impressed and touched to see that many professionals are working hard to find answers, a treatment and ultimately a cure to our condition. [raredr.com]
There is currently no treatment for these conditions; though optimizing and standardizing care and care delivery can promote significant gains in quality of life and survival. [clinicaltrials.gov]
He is currently involved in multiple clinical trials of novel genetic interventions for the treatment of spinal muscular atrophy and Duchenne muscular dystrophy. [books.google.com]

Prognosis
Symptoms are managed for each individual and may involve the coordination of several healthcare specialists. [3] Prognosis [ edit ] There is an open prognosis because this disease has an unknown evolution. [en.wikipedia.org]
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 - Limb-girdle muscular dystrophy- type 1B The gene for LGMD 1B has been linked to chromosome 1q11-q21. This form of LGMD was linked in several families in 1997. [checkorphan.org]
Prognosis is usually largely influenced by cardiac status. [academic.oup.com]
Genetic counselling provides information on the inheritance pattern, risks to other family members, and the ‘prognosis’ (likely outcome of the disorder). [mda.org.au]
