Laboratorio de Investigaciones Aplicadas a Neurociencias, Fundación para la Lucha contra las Enfermedades Neurológicas de la Infancia RCV003881698 SCV004565348 pathogenic Desmin-related myofibrillar myopathy no assertion criteria provided clinical testing The c.1059_1061dupGGA mutation in DES involves the duplication of Glu at position 353 of DES. According to guidelines of the American College of Medical Genetics and Genomics, in-frame insertions are considered moderate indicative of pathogenicity (Richards et al 2015). Additionally, this mutation is located in exon 6 of the protein, which is part of the highly conserved coil 2B domain (known to govern DES polypeptide assembly into and subsequent higher-order structures; Bar et al 2004; Goebel et al 2011; Walter et al 2007) and where many pathogenic mutations were observed in patients. Moreover, disruptive DES filament assembly was in vitro observed in the presence of the mutation (doi.org/10.21203/rs.3.rs-3805874/v1).
