We report a case of a 53-year-old female presenting with a new-onset heart failure that was contributed secondary to noncompaction cardiomyopathy. The diagnosis was made by echocardiogram and confirmed by cardiac MRI. Noncompaction cardiomyopathy (also known as ventricular hypertrabeculation) is a newly discovered disease. It is considered to be congenital (genetic) cardiomyopathy. It is usually associated with genetic disorders and that could explain the genetic pathogenesis of the non-compaction cardiomyopathy. Our case had a history of Charcot-Marie-Tooth disease. There is a high incidence of arrhythmia and embolic complications. The treatment usually consists of the medical management, defibrillator placement, and lifelong anticoagulation. Heart transplantation will be the last resort.

ObjectiveNeurofilaments are the major scaffolding proteins for the neuronal cytoskeleton, and variants in NEFH have recently been described to cause axonal Charcot-Marie-Tooth disease type 2CC (CMT2CC).MethodsIn this large observational study, we present phenotype–genotype correlations on 30 affected and 3 asymptomatic mutation carriers from eight families.ResultsThe majority of patients presented in adulthood with motor-predominant and lower limb-predominant symptoms and the average age of onset was 31.0±15.1 years. A prominent feature was the development of proximal weakness early in the course of the disease. The disease progressed rapidly, unlike other Charcot-Marie-Tooth disease (CMT) subtypes, and half of the patients (53%) needed to use a wheelchair on average 24.1 years after symptom onset. Furthermore, 40% of patients had evidence of early ankle plantarflexion weakness, a feature which is observed in only a handful of CMT subtypes. Neurophysiological studies and MRI of the lower limbs confirmed the presence of a non-length-dependent neuropathy in the majority of patients.All families harboured heterozygous frameshift variants in the last exon of NEFH, resulting in a reading frameshift to an alternate open reading frame and the translation of approximately 42 additional amino acids from the 3' untranslated region (3′-UTR).ConclusionsThis phenotype–genotype study highlights the unusual phenotype of CMT2CC, which is more akin to spinal muscular atrophy rather than classic CMT. Furthermore, the study will enable more informative discussions on the natural history of the disease and will aid in NEFH variant interpretation in the context of the disease’s unique molecular genetics.

Tooth Disease

Charcot-Marie-Tooth disease is a heterogenous group of genetic disorders, presenting the phenotype of a chronic progressive neuropathy affecting both the motor nerves, and thesensitive ones. The disease generally develops before the age of 20 years in the lower limbs. The evolution is chronic and progresses slowly. Charcot-Marie-Tooth disease is one of most commonly inherited neurological disorders, affecting about one in 2,500 people in the United States and 2,8 million people around the world. The present paper intends to be a contribution to improving kinetic treatment programme for Charcot-Marie-Tooth during adolescence. For the research purposes we have monitored an adolescent male patient who benefited from a customized kinetic treatment for six months. The analysis of our recorded data highlighted the progress made (increased joint mobility, improvement of dynamic balance, pain reduction, improvement of foot aesthetics, as well as increase of the quality of life).

Abstract Vincristine (VCR), a microtubule inhibitor that arrests the cell cycle by blocking metaphase of mitosis, is unique among the vinca alkaloids for causing polyneuropathy. Patients with increased risk of VCR neurotoxicity include the elderly and those with prior history of neuropathy-prone medical conditions. Identifying such risk factors prior to the development of neurotoxicity should be a goal prior to VCR administration. Clinicians should obtain a thorough medical and family history of neuropathies in any child scheduled to receive neurotoxic medications to avoid exacerbating an underlying disorder. We report a case of a young child with newly diagnosed medulloblastoma who started treatment on a VCR-containing chemotherapy regimen following surgery and craniospinal radiation. She subsequently developed severe peripheral polyneuropathy and new enhancement of the cranial and nerve roots following a relatively low cumulative dose of VCR and was diagnosed with previously unidentified Charcot–Marie–Tooth disease (CMTD) Type 1A. This case highlights that an evaluation of risk factors should be completed prior to initiation of neurotoxic chemotherapies and advocates for testing for inherited neuropathies such as CMTD even in asymptomatic patients when hereditary neuropathy is suspected.

Charcot-Marie-Tooth disease (CMT) is a progressive hereditary neuromuscular neuropathy with pathology in the myelin sheath or the axon. CMT caused by mutations in the Ganglioside-induced differentiation associated protein 1 (GDAP1) gene has been described by a spectrum of phenotypic presentations. GDAP1 is a mitochondrial protein responsible for protecting neuronal bodies from oxidative stress. It is associated with axonal and demyelinating pathophysiology with recessive and dominant modes of inheritance.We describe a case of a 9-year-old Puerto Rican female with clinical and electrodiagnostic results compatible with an axonal sensory-motor neuropathy where a genetic test describes a homozygous GDAP1 missense mutation at the c.692C>T (p.Pro231Leu), previously undetected in a pediatric Latino patient. Mutations in GDAP1 have been previously described in Tunisian, Old Order Amish, European and Japanese families with varying modes of inheritance. To our knowledge, this homozygous variant presentation of the GDAP1 gene is the first to be described in a pediatric Puerto Rican patient without a family history of hereditary sensory motor neuropathy.
