Molecular genetics studies in Polish Charcot-Marie-Tooth families.

چکیده
Charcot-Marie-Tooth (CMT) disorders are the extremely heterogeneous group of diseases of the peripheral nervous system in humans with a prevalence of 1: 2500. Up to date mutations in 30 genes have been reported in various CMT forms. In numerous CMT types only locus is known and some CMT forms were shown not to be linked with any known locus. Genetic studies in CMT disorders cover a wide spectrum of problems ranging from identification of novel mutations through studies of pathogenic nature of mutations to genotype-phenotype correlations. The aim of this study was to present the main directions of genetic analysis performed in Polish families with CMT disease.

Background and aims: Charcot Marie Tooth disease (CMT) is the most prevalent hereditary neuropathy and its frequency is 1 in 2500. CMT is a heterogeneous disease and has different clinical symptoms. The prevalence of CMT and involved genes differ in different countries. CMT patients experience considerable sleep problems and a higher risk of decreased quality of life. In this w...

Charcot-Marie-Tooth disease (CMT) is the most common hereditary neuropathy of the peripheral nervous system with a wide range of severity and age of onset. CMT patients share similar phenotypes which make it often impossible to identify the disease types based on clinical presentation and electrophysiological studies alone. In recent years, novel genetic diagnostic approaches such as whole exom...

Sixty-seven patients in 29 families with the diagnosis of Charcot-Marie-Tooth disease or hereditary motor and sensory neuropathy in northern Sweden were examined by pedigree and DNA analysis for the CMT1a duplication within chromosome 17p11.2. There were 39 patients in nine families with Charcot-Marie-Tooth type 1 and autosomal dominant inheritance and in all these cases the duplication was see...
متن کاملMolecular genetics of charcot-marie-tooth disease: from genes to genomes.
Charcot-Marie-Tooth disease (CMT) is a heterogeneous group of disorders of the peripheral nervous system, mainly characterized by distal muscle weakness and atrophy leading to motor handicap. With an estimated prevalence of 1 in 2,500, this condition is one of the most commonly inherited neurological disorders. Mutations in more than 30 genes affecting glial and/or neuronal functions have been ...
متن کاملCharcot-Marie-Tooth Disease Type 4H Resulting from Compound Heterozygous Mutations in FGD4 from Nonconsanguineous Korean Families.
Charcot-Marie-Tooth disease type 4H (CMT4H) is an autosomal recessive demyelinating subtype of peripheral enuropathies caused by mutations in the FGD4 gene. Most CMT4H patients are in consanguineous Mediterranean families characterized by early onset and slow progression. We identified two CMT4H patients from a Korean CMT cohort, and performed a detailed genetic and clinical analysis in both ca...
