Guide To The Types Of Muscular Dystrophy

Limb-Girdle Muscular Dystrophy

Limb-girdle muscular dystrophy (LGMD) is an incredibly varied group of genetic disorders. The subtypes of the disease are sorted into categories based on the inheritance and gene affected. LGMD most often shows symptoms in the muscles of the shoulders and hips closest to the body's center. The disease takes its name from the shoulder and hip girdles. These bony structures surround the shoulders and hips, and they're called limb girdles. All types of limb-girdle muscular dystrophy cause muscle wasting and weakness in the muscles that connect to these structures. However, since there are many types caused by different gene variances, other aspects of the condition can vary widely. The severity, speed of progression, and age of symptom onset vary widely. Some types of limb-girdle muscular dystrophy cause weakening of the heart muscle, and some can weaken the respiratory muscles.
