This summary comes from the ClinGen Evidence Repository: The NM_001005361.3:c.1565G>A variant in DNM2 is a missense variant predicted to cause substitution of arginine by histidine at amino acid 522 (p.Arg522His). The variant is absent from gnomAD v4.1.0 meeting PM2_Supporting. DNM2, in which the variant was identified, is defined by the ClinGen Congenital Myopathies VCEP as a gene that has a low rate of benign missense variation and where pathogenic missense variants are a common mechanism of disease (PP2). The REVEL computational prediction analysis tool gives a score of 0.892, which is above the threshold necessary to apply PP3. This variant has been reported in at least eight probands with centronuclear myopathy, of which two were identified to be de novo occurrences (PS2, PS4; PMIDs: 20227276, 29105112, 32826616; Baylor Genetics, GeneDx, Athena Diagnostics, ClinVar: SCV000807289.2, SCV000329752.6, SCV000841851.1; VCEP Internal data contributor). Additionally, the variant segregated with disease in 4 family members meeting PP1_Moderate (PMID:20227276). Live correlative scanning ion conductance microscopy (SICM) and fluorescence confocal microscopy (FCM) showed that the p.Arg522His variant slows down the formation of clathrin-coated pits in skin fibroblasts from patients and in Cos-7 cells expressing corresponding dynamin mutants (PS3_Supporting, PMID:31017801). In summary, the variant meets the criteria to be classified as pathogenic for autosomal dominant centronuclear myopathy. ACMG/AMP criteria met, as specified by the ClinGen Congenital Myopathies VCEP: PS2, PS4, PP1_Moderate, PS3_Supporting, PM2_Supporting, PP2, PP3 (ClinGen Congenital Myopathies VCEP specifications version 1.0.0; 4/14/2025 LINK:https://erepo.genome.network/evrepo/ui/classification/CA172101/MONDO:0018947/148
