  • als5 spg11 kiaa1840 mutations cause autosomal recessive axonal charcot marie Tooth Disease

    Abstract:

    Charcot-Marie-Tooth Disease is a group of hereditary peripheral neuropathies that share clinical characteristics of progressive distal muscle weakness and atrophy, foot deformities, distal sensory loss, as well as diminished tendon reflexes. Hundreds of causative DNA changes have been found, but much of the genetic basis of the Disease is still unexplained. Mutations in the ALS5/SPG11/KIAA1840 gene are a frequent cause of autosomal recessive hereditary spastic paraplegia with thin corpus callosum and peripheral axonal neuropathy, and account for ∼ 40% of autosomal recessive juvenile amyotrophic lateral sclerosis. The overlap of axonal Charcot-Marie-Tooth Disease with both Diseases, as well as the common autosomal recessive inheritance pattern of thin corpus callosum and axonal Charcot-Marie-Tooth Disease in three related patients, prompted us to analyse the ALS5/SPG11/KIAA1840 gene in affected individuals with autosomal recessive axonal Charcot-Marie-Tooth Disease. We investigated 28 unrelated families with autosomal recessive axonal Charcot-Marie-Tooth Disease defined by clinical, electrophysiological, as well as pathological evaluation. Besides, we screened for all the known genes related to axonal autosomal recessive Charcot-Marie-Tooth Disease (CMT2A2/HMSN2A2/MFN2, CMT2B1/LMNA, CMT2B2/MED25, CMT2B5/NEFL, ARCMT2F/dHMN2B/HSPB1, CMT2K/GDAP1, CMT2P/LRSAM1, CMT2R/TRIM2, CMT2S/IGHMBP2, CMT2T/HSJ1, CMTRID/COX6A1, ARAN-NM/HINT and GAN/GAN), for the genes related to autosomal recessive hereditary spastic paraplegia with thin corpus callosum and axonal peripheral neuropathy (SPG7/PGN, SPG15/ZFYVE26, SPG21/ACP33, SPG35/FA2H, SPG46/GBA2, SPG55/C12orf65 and SPG56/CYP2U1), as well as for the causative gene of peripheral neuropathy with or without agenesis of the corpus callosum (SLC12A6). Mitochondrial disorders related to Charcot-Marie-Tooth Disease type 2 were also excluded by sequencing POLG and TYMP genes. An additional locus for autosomal recessive Charcot-Marie-Tooth Disease type 2H on chromosome 8q13-21.1 was excluded by linkage analysis. Pedigrees originated in Italy, Brazil, Canada, England, Iran, and Japan. Interestingly, we identified 15 ALS5/SPG11/KIAA1840 mutations in 12 families (two sequence variants were never reported before, p.Gln198* and p.Pro2212fs*5). No large deletions/duplications were detected in these patients. The novel mutations seemed to be pathogenic since they co-segregated with the Disease in all pedigrees and were absent in 300 unrelated controls. Furthermore, in silico analysis predicted their pathogenic effect. Our results indicate that ALS5/SPG11/KIAA1840 is the causative gene of a wide spectrum of clinical features, including autosomal recessive axonal Charcot-Marie-Tooth Disease.

  • De novo PMP2 mutations in families with type 1 Charcot-Marie-Tooth Disease.
    Brain, 2016
    Co-Authors: William W. Motley, Paulius Palaima, Michael Gonzalez, Julia Wanschitz, Alleene V. Strickland, Wolfgang N. Löscher, Els De Vriendt, Stefan Koppi
    Abstract:

    We performed whole exome sequencing on a patient with Charcot–Marie–Tooth Disease type 1 and identified a de novo mutation in PMP2 , the gene that encodes the myelin P2 protein. This mutation (p.Ile52Thr) was passed from the proband to his one affected son, and segregates with clinical and electrophysiological evidence of demyelinating neuropathy. We then screened a cohort of 136 European probands with uncharacterized genetic cause of Charcot–Marie–Tooth Disease and identified another family with Charcot–Marie–Tooth Disease type 1 that has a mutation affecting an adjacent amino acid (p.Thr51Pro), which segregates with Disease. Our genetic and clinical findings in these kindred demonstrate that dominant PMP2 mutations cause Charcot–Marie–Tooth Disease type 1. * Abbreviations : CMT = : Charcot–Marie–Tooth Disease HMSN = : hereditary motor and sensory neuropathy

  • Diagnosis, natural history, and management of Charcot–Marie–Tooth Disease
    Lancet Neurology, 2009
    Co-Authors: Davide Pareyson, Chiara Marchesi
    Abstract:

    Summary Charcot–Marie–Tooth Disease is the most common inherited neuromuscular disorder. There have been substantial advances in elucidating the molecular bases of this genetically heterogeneous neuropathy and, in most cases, molecular diagnosis is now possible. The diagnostic approach requires careful assessment of clinical presentation and mode of inheritance, nerve-conduction studies, and DNA testing, and current research is focused on assessing natural history and finding effective treatments. Disease course is variable because of genotypic and phenotypic heterogeneity. At present, there is no drug therapy for Charcot–Marie–Tooth Disease, and rehabilitation therapy and surgical procedures for skeletal deformities are the only available treatments, although best practice has not been defined. Animal models are proving useful for the identification of therapeutic targets and approaches. Progesterone antagonists, neurotrophic factors, ascorbic acid, and curcumin have shown promising results in experimental models, and ascorbic acid is being studied in large randomised controlled trials.
