Congenital Fiber-Type Disproportion Myopathy


Presentation

  • Ptosis was present in 43%, one third had scoliosis and two patients had hip dislocation Conclusions: CFTD is one of the rare congenital myopathies, usually presenting with congenital hypotonia and weakness but may also present in later in life.[neurology.org]
  • After a review of the clinical and histopathological aspects of the disease, the present work described craniofacial skeletal and EMG features of a 9-year-old child affected by CFTD.[ncbi.nlm.nih.gov]
  • Congenital hip dislocation and talipes equinovarus may also be present. In rare cases, cardiac involvement, cognitive impairment and cryptorchidism may occur.[orpha.net]
  • While only congenital fiber type disproportion was observed in the younger patient, older patient's biopsy presented aggregates of slow myosin heavy chains, in fiber sub-sarcolemmal region.[readbyqxmd.com]
  • All three cDNA variants were present in the lymphocytes of the patients. Purified IR from 293 cells overexpressing either of the two mutated receptors lacked basal or stimulated IR beta-subunit autophosphorylation.[ncbi.nlm.nih.gov]

Workup

Right Bundle Branch Block
  • Cardiac involvement, suchdisproportion (FTD) on his muscle biopsy performed at 4years of age.At his age of 16 years, hewas pointed out to have atrial-ventricular con-duction block and incomplete right bundle branch block.[documents.tips]

Treatment

  • The second (unrelated) child developed atrial fibrillation with rapid atrioventricular conduction requiring treatment with digoxin.[ncbi.nlm.nih.gov]
  • The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment.[orpha.net]
  • Twelve expertly-authored chapters navigate the nuances of these treatments in an array of contexts and biological systems.[books.google.com]
  • The results of the studies presented in this volume now pave the way for much future research into the pathogenesis of this group of fascinating conditions, leading one day to their treatment. References: 1. Winder SJ, ed.[books.google.com]
  • Treatment - Congenital fiber type disproportion Treatment of Congenital fiber type disproportion may consist of active and passive exercises and physical therapy to promote muscle function.[checkorphan.org]

Prognosis

  • CFTD is characterized by non-progressive childhood neuromuscular disorders with a relatively good prognosis and type 1 fiber predominance and smallness.[ncbi.nlm.nih.gov]
  • Prognosis Over time, CFTDM becomes static in more than 90% of patients or even shows improvement and, rarely, is slowly progressive. The documents contained in this web site are presented for information purposes only.[orpha.net]
  • Prognosis - Congenital fiber type disproportion The prognosis is relatively favorable in most patients.[checkorphan.org]
  • Tale quadro, in contrasto a quanto riportato in letteratura, si accompagnato ad una prognosi infausta con decesso della bambina a 17 mesi. Address reprint requests to Dr. P.[docslide.com.br]

Etiology

  • Etiology Causative mutations have been identified in two genes, ACTA1 and SEPN1 . Diagnostic methods Diagnosis is based on a combination of clinical presentation and morphologic features observed on skeletal muscle histology.[orpha.net]

  • The diverse etiologies of the disorder as a syndrome rather than a disease and its association in some cases with specific metabolic diseases were first recognized by Martin and colleagues ( Martin et al 1976 ).[medlink.com]
  • Material and Method Muscle tissue was obtained from 21 patients, ranging in age from three months to five years, in order to help evaluate the etiology of motor delay associated with hypotonia.[documentslide.com]

Epidemiology

  • Summary Epidemiology Prevalence is unknown, incidence is estimated to be inferior than 1:50,000 live births. Clinical description Limb weakness may be greatest in the limb girdle and proximal limb muscles, but weakness is never solely distal.[orpha.net]
  • Epidemiology: Worldwide: Incidence:6 per 100,000 live births or 1/10th of all neuromuscular disorders.[slideshare.net]

Prevention

  • Although FTD is not a constant pathological feature of LMNA-myopathy, we should consider the possibility of LMNA-myopathy whenever a diagnosis of CFTD is made and take steps to prevent cardiac insufficiency. Copyright 2014 Elsevier B.V.[ncbi.nlm.nih.gov]
