Camuratiho-Engelmannův syndrom imitující muskulární dystrofii

Camurati-Engelmann’s Syndrome Imitation Muscular Dystrophy

Camurati-Engelmann’s skeletal dysplasia (CESD) is characterized by progressive diaphyseal hyperostosis ofcortices and in base of skull, leg pains, waddling gait, asthenic appearance and muscle weakness most evident inlow limb girdle. Hyperostosis may progress to deafness, headaches and optic nerve atrophy due to compression.Adolescence with puberty may be delayed. Disorder is autosomal dominant inherited and shows a wide varianceeven intrafamilial in expression of symptoms. The mutation for type I was identified in gene TGFB1 on 19q13.1.Authors report a family with occurrence of CESD in at least three generations in which the youngest patientswere diagnosed as mitochondrial or autosomal recessive muscular dystrophy. Only detection of R218C mutationin TGFB1 gene allows to estimate of correct clinical prognosis for family members.
