Variant summary

Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PM2_SupportingPS4PS2PP2PP3PP1_ModeratePS3_Supporting

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

Genes affected
DNM2 (HGNC:2974): (dynamin 2) Dynamins represent one of the subfamilies of GTP-binding proteins. These proteins share considerable sequence similarity over the N-terminal portion of the molecule, which contains the GTPase domain. Dynamins are associated with microtubules. They have been implicated in cell processes such as endocytosis and cell motility, and in alterations of the membrane that accompany certain activities such as bone resorption by osteoclasts. Dynamins bind many proteins that bind actin and other cytoskeletal proteins. Dynamins can also self-assemble, a process that stimulates GTPase activity. Five alternatively spliced transcripts encoding different proteins have been described. Additional alternatively spliced transcripts may exist, but their full-length nature has not been determined.
