Prognosis
If you or your child has been told the diagnosis is SMA but it’s not the chromosome 5-related type, talk with your doctor and perhaps a genetic counselor to find out more about the genetics and prognosis for the particular SMA involved. [mda.org]
[ edit ] Prognosis depends on the individual form of MD. [en.wikipedia.org]
Genetic counselling provides information on the inheritance pattern, risks to other family members, and the ‘prognosis’ (likely outcome of the disorder). [mda.org.au]
Chronic pain can occur, and pain management should be part of care. [ 19 ] Prognosis This depends on the type of LGMD and whether there is cardiac or respiratory involvement. In general, all types of LGMD progress with time. [patient.info]
To date, data for all CMD subtypes are insufficient to make any firm genotype / phenotype correlations or to provide definitive prognosis or anticipatory guidance based on CMD subtype. [ncbi.nlm.nih.gov]
Etiology
The low call percentage or mutation detection rate for individual gene tests is due mostly to incorrect presumption of genetic etiology and suspicion of the incorrect gene. [journals.plos.org]

Accordingly, a prevalence for LGMD2I could be estimated that is within the range of other, more frequent muscular dystrophies. 15 However, epidemiological studies are warranted to prove this hypothesis. [jmg.bmj.com]
Pathophysiology
This new set of data explains, at least in part, why many of these disorders are interconnected, though the primary pathophysiological events, such as gene mutations, may be different for each disorder. [books.google.de]
Mechanism [ edit ] In terms of the mechanism of congenital muscular dystrophy, one finds that though there are many types of CMD the glycosylation of α-dystroglycan and alterations in those genes that are involved are an important part of this conditions pathophysiology [en.wikipedia.org]
Pathophysiology The pathophysiology of the congenital muscular dystrophies depends on the specific genetic defect for each of the dystrophies and is discussed with each of the congenital muscular dystrophies below. [emedicine.medscape.com]
Although the pathophysiology of the white matter changes has not been completely elucidated, the majority of investigators postulate that disruption of the blood-brain barrier associated with laminin α-2 leads to increased water content, which results [spandidos-publications.com]
Prevention
Protein coding - M0QYV8 - 3' truncation in transcript evidence prevents annotation of the end of the CDS. CDS 3' incomplete Transcript Support Level 4, for transcripts supported by an EST flagged as suspect. [ensembl.org]
Thus, overexpressing Smad7 suppresses Smad2/3 signaling, promotes muscle hypertrophy and prevents muscle wasting. [aavogen.com]
A shortage of FKRP prevents the normal glycosylation of α-dystroglycan. As a result, α-dystroglycan can no longer effectively anchor cells to the proteins and other molecules that surround them. [ghr.nlm.nih.gov]
