Variable phenotypic expression of a MECP2 mutation in a family / K. AUGENSTEIN in Journal of Neurodevelopmental Disorders, 1-4 (December 2009)
[article]
Titre : Variable phenotypic expression of a MECP2 mutation in a family Type de document : Texte imprimé et/ou numérique Auteurs : K. AUGENSTEIN, Auteur ; J. B. LANE, Auteur ; A. HORTON, Auteur ; C. SCHANEN, Auteur ; A. K. PERCY, Auteur Article en page(s) : p.313 Langues : Anglais (eng) Mots-clés : Dystonia Mecp2 Male Mutation Phenotype-genotype Rett syndrome X chromosome inactivation Index. décimale : PER Périodiques Résumé : We report a three generation family in which five members, three females and two males, demonstrate a 44 bp deletion (1164-1207del44) in the MECP2 gene associated with Rett syndrome, leading to a truncation of the C-terminus of the protein. Two of the three females and both males do not meet RTT criteria whereas the youngest female has classic RTT. Both males demonstrated a clear pattern of progressive involvement including dystonia. The transmitting females do not demonstrate features of RTT as a result of unbalanced X chromosome inactivation (XCI) and were only identified as carriers following the evaluation of the affected males and the girl with classic RTT. As such, accurate assessment of the precise frequency of MECP2 mutations in carrier females with mild cognitive impairment or borderline cognitive function will be under-represented unless an affected offspring is recognized. Strategies for accurate diagnosis in such instances should be considered carefully.

Titre : WDFY3 mutation alters laminar position and morphology of cortical neurons Type de document : Texte imprimé et/ou numérique Auteurs : Zachary A. SCHAAF, Auteur ; Lyvin TAT, Auteur ; Noemi CANNIZZARO, Auteur ; Ralph GREEN, Auteur ; Thomas RULICKE, Auteur ; Simon HIPPENMEYER, Auteur ; Konstantinos S. ZARBALIS, Auteur Article en page(s) : 27 p. Langues : Anglais (eng) Mots-clés : Adaptor Proteins, Signal Transducing/genetics Animals Autistic Disorder/genetics Autophagy-Related Proteins/genetics Cerebral Cortex/cytology Humans Mice Mutation Neurogenesis/genetics Neurons/cytology Cerebral cortex Dendrites Dendritic spines Excitatory neurons Neuronal migration Wdfy3 Index. décimale : PER Périodiques Résumé : BACKGROUND: Proper cerebral cortical development depends on the tightly orchestrated migration of newly born neurons from the inner ventricular and subventricular zones to the outer cortical plate. Any disturbance in this process during prenatal stages may lead to neuronal migration disorders (NMDs), which can vary in extent from focal to global. Furthermore, NMDs show a substantial comorbidity with other neurodevelopmental disorders, notably autism spectrum disorders (ASDs). Our previous work demonstrated focal neuronal migration defects in mice carrying loss-of-function alleles of the recognized autism risk gene WDFY3. However, the cellular origins of these defects in Wdfy3 mutant mice remain elusive and uncovering it will provide critical insight into WDFY3-dependent disease pathology. METHODS: Here, in an effort to untangle the origins of NMDs in Wdfy3(lacZ) mice, we employed mosaic analysis with double markers (MADM). MADM technology enabled us to genetically distinctly track and phenotypically analyze mutant and wild-type cells concomitantly in vivo using immunofluorescent techniques. RESULTS: We revealed a cell autonomous requirement of WDFY3 for accurate laminar positioning of cortical projection neurons and elimination of mispositioned cells during early postnatal life. In addition, we identified significant deviations in dendritic arborization, as well as synaptic density and morphology between wild type, heterozygous, and homozygous Wdfy3 mutant neurons in Wdfy3-MADM reporter mice at postnatal stages. LIMITATIONS: While Wdfy3 mutant mice have provided valuable insight into prenatal aspects of ASD pathology that remain inaccessible to investigation in humans, like most animal models, they do not a perfectly replicate all aspects of human ASD biology. The lack of human data makes it indeterminate whether morphological deviations described here apply to ASD patients or some of the other neurodevelopmental conditions associated with WDFY3 mutation. CONCLUSIONS: Our genetic approach revealed several cell autonomous requirements of WDFY3 in neuronal development that could underlie the pathogenic mechanisms of WDFY3-related neurodevelopmental conditions. The results are also consistent with findings in other ASD animal models and patients and suggest an important role for WDFY3 in regulating neuronal function and interconnectivity in postnatal life.

Grâce aux supports numériques, la rééducation peut se poursuivre au-delà des séances et peut même être réalisée à distance. Ces changements importants au niveau des pratiques de rééducation, d’échanges et de partage de données ne peuvent être improvisés, Ils nécessitent l’acquisition par les orthophonistes de compétences numériques complémentaires, indispensables pour garantir aux patients la protection de leurs données de santé recueillies et transmises, ainsi que la qualité du diagnostic et des soins de rééducation dispensés. Le nouveau référentiel de formation initiale et la formation continue vont permettre aux orthophonistes d’enrichir leurs compétences numériques et de mieux valoriser leurs pratiques grâce aux travaux de recherche qui commencent à se développer dans ce domaine.

This study aimed to investigate the impact of dystonia, dietary intakes, and clinical severities on growth patterns in a Taiwanese cohort of RTT. We recruited 44 RTT patients with MECP2 mutation for analysis. For individuals ?18?years of age, in comparison to the RTT-specific growth chart which comprised American RTT cohort, the body height was right-shifted to a higher percentile, whereas the body weight was left-shifted to a lower percentile. Furthermore, the body mass index was significantly decreased when compared to RTT-specific growth chart (p = 0.01). Higher degree of overall disease severity (odd ratio = 1.159; 95% CI = 1.063-1.264; p = 0.001) and hand use impairment (odd ratio = 2.017; 95% CI = 1.037, 3.921; p = 0.039) were associated with more severe growth patterns. All individuals had dystonia at certain variable degrees. The dystonia worsened with age (p?0.001) but did not have significant impact on growth deficit. Most of our cohort had adequate protein (97.37%) and energy (58.97%) intakes. The fiber intakes were generally low, with about 38 (97.4%) individuals did not meet the daily reference intakes of fiber. The protein intake was significantly lower in individuals with severe growth deficit (p = 0.04). Our study shows that ethnicity should be considered when comparing RTT individuals' growth pattern to the RTT-specific growth chart. Further, disease severity, genotypes, and nutrition exert important impacts on RTT-growth pattern. LAY SUMMARY: Growth impairment is an important issue in Rett syndrome and the underlying patho-mechanism is multifactorial. Higher degree of overall disease severity and hand use impairment were associated with more severe growth pattern deficits. Although all individuals had dystonia at certain variable degrees and the dystonia worsened with age, but it did not have significant impact on growth deficit. Nutritional intakes may partially affect growth. Furthermore, ethnicity should be considered when comparing RTT individuals' growth pattern to the RTT-specific growth chart.
