Prognosis for GSD IIB -- formerly
Prognosis for GSD IIB -- formerly:
The extent and severity of the condition is variable - some patients don't have muscle problems or mental retardation. Females are carriers and such tend to have a later onset of symptoms but may still develop quite severe symptoms. Sudden death due to heart failure can occur during the teenage years for males and in the forties for females. Heart symptoms can progress quite rapidly, going from virtually no symptoms to heart failure within six months in some cases. Most male patients die before the age of twenty but female patients can live for up to 40 years or longer.
