A rare genetic lethal non-dystrophic congenital myopathy disorder characterised, antenatally, by fetal akinesia, intrauterine growth restriction and polyhydramnios, and, following birth, by severe neonatal hypotonia, severe generalised skeletal, bulbar and respiratory muscle weakness, multiple flexion contractures, and normal creatine kinase serum levels. Ultrastructurally, loss of integrin alpha7, beta2-syntrophin and alpha-dystrobrevin from the muscle sarcolemma and disruption of sarcomeres with disorganisation of the Z band are observed. There is evidence this disease is caused by homozygous mutation in the CNTN1 gene on chromosome 12q12.	componente obsoleto (metadato fundacional)
