Additional Information:

Description: (OMIM) This disorder represents 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 ...
Clinical Description OMIM Hartley et al. (2007) reported 2 unrelated but consanguineous families from Qatar and Sri Lanka, respectively, in which 2 sibs in each family had a severe congenital myopathy particularly affecting the diaphragm. The older daughter in the first ...
Molecular genetics OMIM In 7 patients from 5 families with EMARDD, Logan et al. (2011) identified homozygous or compound heterozygous mutations in the MEGF10 gene (612453.0001-612453.0006). All but 1 of the mutations were truncating, resulting in loss of protein function. ...
