UniProtKB/Swiss-Prot : 76 Myopathy, early-onset, areflexia, respiratory distress, and dysphagia: An autosomal recessive congenital myopathy characterized by onset at birth, or early in infancy, of respiratory distress caused by diaphragmatic weakness. Additional features are dysphagia resulting in poor feeding, failure to thrive, poor head control, facial weakness, cleft palate, contractures and scoliosis. Affected individuals become ventilator-dependent, and most require feeding by gastrostomy. The disorder results in severe muscle weakness and most patients never achieve walking. Death from respiratory failure in childhood occurs in about half of patients. Muscle biopsies from affected individuals show myopathic changes, replacement of myofibers with fatty tissue, small and incompletely fused muscle fibers, and variation in fiber size. Short regions of sarcomeric disorganization with few or no mitochondria (minicores) have been observed in some cases.

MalaCards based summary : Myopathy, Areflexia, Respiratory Distress, and Dysphagia, Early-Onset, also known as emardd, is related to myopathy and dysphagia, and has symptoms including torticollis and facial paresis. An important gene associated with Myopathy, Areflexia, Respiratory Distress, and Dysphagia, Early-Onset is MEGF10 (Multiple EGF Like Domains 10). Affiliated tissues include lung, and related phenotypes are seizures and pectus excavatum

OMIM : 58 EMARDD is a congenital myopathy characterized by proximal and generalized muscle weakness, respiratory difficulties, joint contractures, and scoliosis. More variable features include cleft palate and feeding difficulties. There is variable severity: some patients become ventilator-dependent, never achieve walking, and die in childhood, whereas others have a longer and more favorable course (summary by Logan et al., 2011 and Boyden et al., 2012).
