Nemaline myopathy with dilated cardiomyopathy in childhood.
We present a case of a 9-year-old boy with nemaline myopathy and dilated cardiomyopathy. The combination of nemaline myopathy and cardiomyopathy is rare, and this is the first reported case of dilated cardiomyopathy associated with childhood-onset nemaline myopathy. A novel mutation, p.W358C, in ACTA1 was detected in this patient. An unusual feature of this case was that the patient's cardiac f...
متن کاملDivergent abnormal muscle relaxation by hypertrophic cardiomyopathy and nemaline myopathy mutant tropomyosins.
Mutations in tropomyosin (Tm) have been linked to distinct inherited diseases of cardiac and skeletal muscle, hypertrophic cardiomyopathy (HCM), and nemaline myopathy (NM). How HCM and NM mutations in nearly identical Tm proteins produce the vastly divergent clinical phenotypes of heightened, prolonged cardiac muscle contraction in HCM and skeletal muscle weakness in NM is currently unknown. We...

متن کاملCytoplasmic body myopathy with hypertrophic cardiomyopathy.
A patient with cytoplasmic body myopathy presented muscle hypotonia from birth and developed progressive muscular atrophy and weakness, scoliosis, contracture of joints and cardiorespiratory failure. At the age of 17, he died of heart failure. Post mortem examination revealed severe hypertrophy of cardiac walls and generalized muscular atrophy. Microscopic examination showed many cytoplasmic bo...
متن کاملHypertrophic obstructive cardiomyopathy in an infant with an adrenocortical tumor.
Nonfamilial cardiomyopathies in childhood have been only sporadically ascribed to endocrine disorders. We report on a 4-month-old male infant presenting with Cushing's syndrome associated with excessive body weight (8.9 kg; >97th percentile) and features of virilization (Tanner stage 2 for pubic hair development). Abdominal sonography showed a large adrenal tumor. Echocardiography revealed myoc...
