Sarcoglycan, epsilon Proteins (SGCE)

Human Sarcoglycan, epsilon (SGCE) interaction partners

1. The characterization of iPSC-derived cortical neurons with mutations in SGCE revealed that these cells are a suitable model mirroring the endogenous environment in the myoclonus-dystonia patient brain, especially, when focusing on concrete molecular aspects of the disease mechanism.

2. A novel nonsense SGCE mutation was found in a Japanese family with myoclonus-dystonia.

3. This study demonstrated that Psychiatric features are not likely to be related with the SGCE mutation itself but just bespeak disability in clinical MD syndrome regardless of the SGCE mutation.

4. SGCE mutation can cause a broad range of clinical symptoms between and within families. We should consider MDS as a differential diagnosis for patients with paroxysmal walking abnormalities and/or myoclonic movements.

5. Tata confirms that SGCE mutations are most commonly identified in Myoclonus dystonia syndrome patients with (1) age at onset

6. found one patient with a novel heterozygous frameshift mutation in the DYT11 gene

7. The co-occurrence of seizures and myoclonus-dystonia suggests that they are both due to the same underlying SGCE mutation

8. A novel frameshift mutation of the SGCE gene in an Iranian family with Myoclonus-dystonia syndrome confirming the variability of the clinical symptoms caused by the same mutation within members of a family.

9. In myoclonus-dystonia syndrome patients a substantial mutation in exon 3 of SGCE gene was found.

10. The results of this study suggested performing gene dosage analysis by multiple ligation-dependent probe amplification (MLPA) to individuate large SGCE deletions that can be responsible for complex phenotypes.

11. SGCE mutations are associated with a specific psychiatric phenotype consisting of compulsivity, anxiety and alcoholism in addition to the characteristic motor phenotype.

12. Although reduced penetrance in DYT11-MD has been attributed to the maternal imprinting epsilon-sarcoglycan mutations, NM-DYT11 carriers showed significant metabolic abnormalities that are not explained by this genetic model.

13. anxiety disorders and executive dysfunctions may be part of the phenotype of myoclonus-dystonia patients with a DYT11 mutation

14. The results of this review confirmed the association of epsilon-sarcoglycan gene mutations with psychiatric disease and suggest a possible separation of the motor and psychiatric effects.

15. This report presents a novel mutation in the SGCE gene causing myoclonus dystonia and extends the phenotype of myoclonus dystonia to also include alcohol-induced dystonia.

16. Dystonia severity in twenty-five clinically affected DYT11 mutation carriers is strongly correlated with increased gray matter volume in bilateral putamina.

17. This study demonistrated that Familial 7q21.3 microdeletion involving epsilon-sarcoglycan causing myoclonus dystonia, cognitive impairment, and psychosis.

18. the mRNA expression level of SGCE were significantly up-regulated in tumorous liver tissues compared with corresponding nontumorous counterparts

19. This study provides the first neurophysiological evidence of cerebellar dysfunction in DYT11 dystonia and supports a role of cerebellar dysfunction in the myoclonus-dystonia phenotype.

20. Biased SGCE gene expression is based on parent of origin rather than on a strictly dichotomous maternal imprinting mechanism, consistent with clinical observations.

Pig (Porcine) Sarcoglycan, epsilon (SGCE) interaction partners

1. Paternal expression was demonstrated by microarray profiling of swine parthenotes and bi-parental fetal tissues and by an orthogonal method (QUASEP) with reciprocal interbreed crosses.

Mouse (Murine) Sarcoglycan, epsilon (SGCE) interaction partners

1. Sgcem+/pGt mice show germline absence of major and brain-specific isoforms harboring exons 3' to intron 9. Sgce was maternally-imprinted in our mouse model. Sgcem+/pGt mice exhibited tiptoe walking and occasional stimulus-induced appendicular flexion posturing preweanling. Adult Sgcem+/pGt mice showed increased slips on a raised-beam task, anxiety-like behavioral abnormalities, and narrowed hindlimb stance widths.

2. The results suggest that varepsilon-sarcoglycan in the cerebellar Purkinje cells contributes to the motor learning, while loss of varepsilon-sarcoglycan in other brain regions may contribute to nuclear envelope abnormality, myoclonus and motor coordination deficits.

3. results suggest that the loss of epsilon-sarcoglycan in the striatum contributes to motor deficits, while it alone does not produce abnormal nuclear envelopes or myoclonus

4. impaired ectodomain shedding of M68T, a process that occurs physiologically for epsilon-sarcoglycan resulting in the lysosomal trafficking of the intracellular C-terminal domain of the protein. ( epsilon-sarcoglycan )

5. Sgca-;Sgce-null mouse shows a complete loss of residual sarcoglycans and a strong reduction in both dystrophin and dystroglycan.

6. Data describe mice carrying mutations in both Dyt1 and Sgce and show that these double mutant mice show earlier onset of motor deficits in beam-walking test.

7. Sgce gene is imprinted, with exclusive expression from the paternal allele.

8. These results suggest that the two epsilon-SG isoforms might play different roles in synaptic functions of the central nervous system.

9. High expression levels of epsilon-sarcoglycan mRNA and protein were found in the mitral cell layer of the olfactory bulb, the Purkinje cell layer in cerebellum, and the monoaminergic neurons in the mouse midbrain.

10. diverse symptoms associated with myoclonus-dystonia are indeed resulted from a single SGCE gene mutation that leads to alterations of dopaminergic and serotonergic systems.

11. Data demonstrate a novel function of the sarcoglycan complex in whole body glucose homeostasis and skeletal muscle metabolism, suggesting that the impairment of the skeletal muscle metabolism influences the pathogenesis of muscular dystrophy.
