MalaCards based summary: Myopathy, X-Linked, with Excessive Autophagy, also known as x-linked myopathy with excessive autophagy, is related to danon disease and parietal foramina 2, and has symptoms including difficulty running, proximal muscle weakness in lower limbs and difficulty climbing stairs. An important gene associated with Myopathy, X-Linked, with Excessive Autophagy is VMA21 (VMA21 Vacuolar H+-ATPase Homolog (S. Cerevisiae)), and among its related pathways is Muscular Dystrophies and Dystrophin-Glycoprotein Complex. Affiliated tissues include skeletal muscle and heart, and related mouse phenotypes are muscle and cardiovascular system.

NIH Rare Diseases:45 X-linked myopathy with excessive autophagy (xmea) is a type of inherited myopathy (muscle disease) that mainly affects males. it is characterized by muscle weakness that begins in childhood that slowly worsens over time. weakness involving the upper legs is typically noticed first, affecting activities such as running and climbing stairs. as the condition progresses, men with xmea may experience weakness in their lower legs and arms. some people with xmea remain able to walk as they get older, while others require assistance in adulthood. this disorder is caused by mutations in the vma21 gene and is inherited in an x-linked recessive fashion. last updated: 12/22/2015

UniProtKB/Swiss-Prot:67 Myopathy, X-linked, with excessive autophagy: A muscle disorder characterized by childhood early onset of a slowly progressive proximal limb muscle weakness (especially in legs) and elevation of serum creatine kinase, without evidence of cardiac, respiratory or central nervous system involvement. Histopathological analysis reveals diseased muscle fibers that are not necrotic, but show abnormal autophagic vacuolation as a manifestation of excessive autophagic activity in skeletal muscle cells.
