Variant summary

Our verdict is Likely pathogenic. The variant received 7 ACMG points: 7P and 0B. PM2_Supporting PS4 PP2 PP3

This summary comes from the ClinGen Evidence Repository: The NM_001005361.3:c.1567A>G variant in DNM2 is a missense variant predicted to cause substitution of arginine by glycine at amino acid 523 (p.Arg523Gly). 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. The Z-score in gnomAD v4.1.0 is 4.87 (PP2). The REVEL computational prediction analysis tool gives a score of 0.713, which is above the threshold necessary to apply PP3. This variant has been reported in at least three probands with centronuclear myopathy (PS4; PMIDs: 22396310, 25501959; Genetic Services Laboratory, University of Chicago, ClinVar: SCV000193041.1). In summary, the variant meets the criteria to be classified as likely pathogenic for autosomal dominant centronuclear myopathy. ACMG/AMP criteria met, as specified by the ClinGen Congenital Myopathies VCEP: PS4, PM2_Supporting, PP2, PP3 (ClinGen Congenital Myopathies VCEP specifications version 1.0.0; 6/9/2025).

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.
