Limb-Girdle Muscular Dystrophy Type 1H

Autosomal Dominant Limb-Girdle Muscular Dystrophy Type 1H


Presentation

  • Earlier onset of the disease was observed in a group of patients presenting with muscle weakness and/or calf hypertrophy, and/or occasionally high CK and lactate serum levels.[moh-it.pure.elsevier.com]
  • Central nuclei were occasionally present.[doi.org]
  • Neuromuscular syndromes are presented clinically either as a case study or as an overview from the literature, accompanied by text presenting molecular defects, and differential diagnosis.[books.google.it]
  • The main goal of the present project is to perform a clinical and genetic study aimed to identify the causing genetic defect of a novel form of limb-girdle muscular dystrophies autosomal dominantly transmitted, LGMD1H.[telethon.it]
Chills
  • The specimens from the deltoid or vastus lateralis muscle were oriented, snap-frozen in liquid nitrogen-chilled isopentane, and cryostat-cut sections were stained using standard histochemical methods.[doi.org]

Treatment

  • Key points for each genetic disease are identified to suggest treatment, when available, or the main clinical exams useful in follow-up of patients.[books.google.it]
  • He is currently involved in multiple clinical trials of novel genetic interventions for the treatment of spinal muscular atrophy and Duchenne muscular dystrophy.[books.google.de]
  • Several rare forms are inherited in an autosomal dominant pattern. [2] While there are no treatments which directly reverse the muscle weakness associated with this condition, supportive treatment can decrease the complications. [3] There are at least[rarediseases.info.nih.gov]
  • Magnetic resonance imaging (MRI), perioral skin biopsies, blood-based assays, reverse-protein arrays, proteomic analyses, gene chips and next generation sequencing are the leading diagnostic techniques for LGMD and gene, cell and pharmaceutical treatments[scinapse.io]

Prognosis

  • During her course, she did not show any improvement in her clinical status and was declared by multidisciplinary team specialist to have grave prognosis. Her family decided to initiate comfort care measures, thereafter, patient eventually expired.[pubs.sciepub.com]
  • Page 5 of 7 Molecular diagnosis is crucial for genetic counseling and prognosis [23, 24]. An earlier genetic diagnosis provides better disease management and also protects patients from more invasive clinical evaluation [25].[mafiadoc.com]
