Inding interface. Since the mutation described concerns the substitution of a modest,hydrophobic amino acid (Gly) with a different featuring a rather bulky side chain, positively charged at physiological pH (Arg), it truly is likely that the mutation alters the surface properties of the protein, especially the surface electrostatic potential. Electrostatic interactions across protein interfaces are known to become important to the formation of multimers and complexes that usually represent the biologically active conformation of proteins. Our computational investigations also recommend that the G67RGaribaldi et al. Acta Neuropathologica Communications (2018) six:Page 7 ofmutation alters the surface electrostatic potential, probably impacting the tendency of BTB dimerization in vivo. Nonetheless, this study concerns only one patient and much more evidences are required to conclusively state the effect of mutations in BTB/POZ domain of KBTBD13 gene.three.4. 5.Conclusions In conclusion our findings broaden the clinical, histological and genetical spectrum of the ultra-rare KBTBD13-related myopathy and enlarge pathophysiological knowledges about cGAS Protein Human nemaline myopathies, showing that NEM6 can have an adult onset, could show muscle hypertrophy with peculiar “inside-to-outside” MRI/CT pattern, and may lack of type2-hypotrophy at muscle biopsy. Different domains involved of KBTBD13 could cause the phenotypic variability in NEM6.Authors’ contributions MG: design and style and coordination in the study, clinical information collection, morphological and neuroimaging research, analysis and interpretation with the data, drafting and revising manuscript; FF, ESB: genetic evaluation, analysis and interpretation in the data, drafting and revising manuscript; CAB: molecular modelling; analysis and interpretation of your data, drafting and revising manuscript; GB, CL, SR: electron microscopy study; MV immunohistochemistry and western blot analysis; ESM, CP: western blot evaluation, genetic analysis, evaluation and interpretation with the information; LG, MP, GDR: cellular Recombinant?Proteins CD36 Protein modelling and transfection, evaluation and interpretation from the data, drafting and revising manuscript; EMP, GA: clinical information collection, revising manuscript; NBR: morphological evaluation, electron microscopy study, evaluation and interpretation from the information, revising manuscript.
