Males In males the symptoms of<unk>  are more severe. Features of<unk>  in males are: * An early age of onset of muscle weakness and heart disease (onset in childhood or adolescence) * Some learning problems or intellectual disability can be present * Muscle weakness can be severe and can affect endurance and the ability to walk * Heart disease (cardiomyopathy) can be severe and can lead to a need for medications. It usually progress to heart failure, commonly complicated by atrial fibrillation and embolic strokes with severe neurological disability, leading to death unless heart transplant is performed. * Cardiac conduction abnormalities can occur. Wolff-Parkinson-White syndrome is a common conduction pattern in<unk> . * Symptoms are usually gradually progressive * Some individuals may have visual disturbances, and/or retinal pigment abnormalities *<unk>  is rare and unfamiliar to most physicians. It can be mistaken for other forms of heart disease and/or muscular dystrophies, including Pompe disease. Females In females the symptoms of<unk>  are less severe. Common symptoms of<unk>  in females are: * A later age of onset of symptoms. Many females will not have obvious symptoms until late adolescence or even adulthood. * Learning problems and intellectual disability are usually absent. * Muscle weakness is often absent or subtle. Some females will tire easily with exercise * Cardiomyopathy is often absent in childhood. Some women will develop this in adulthood. Cardiomyopathy can be associated with atrial fibrillation and embolic strokes. * Cardiac conduction abnormalities can occur. Wolff-Parkinson-White syndrome is a common conduction pattern in<unk> . * Symptoms in females progress more slowly than in males. * Some females may have visual disturbances, and/or retinal pigment abnormalities *<unk>  is rare and unfamiliar to most physicians. The milder and more subtle symptoms in females can make it more difficult to diagnose females with<unk>
