Congenital Myopathies
- Centronuclear myopathy (including X-linked myotubular myopathy)
Congenital myopathies with centrally placed nuclei in muscle fibers, caused by MTM1, DNM2, BIN1 and other genes; the X-linked myotubular form (MTM1) is often severe in boys.
- ClinGen rates the link definitive
- 3 GenCC submitters rate it definitive or strong
Broader groupings
Charcot-Marie-Tooth Disease
One of 62 genes linked to it
A group of inherited peripheral neuropathies causing progressive weakness and wasting of the distal muscles and loss of sensation, mainly in the feet and hands.
- ClinGen rates the link definitive
- 3 GenCC submitters rate it definitive or strong
What knowing changes
Genetic counseling, subtype-specific monitoring, physical therapy, orthotics, neurotoxic drug avoidance, gene-specific clinical trials, surveillance for associated features

- Variants with a page
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 3.6 kb of the gene's 113.8 kb; 2,613 of those bases code for the protein.
How a genome test reads DNM2
28
positions in DNM2 where ClinVar classes a change as pathogenic or likely pathogenic
None of them falls in a region short reads find hard.
A whole genome covers all 113.8 kb of DNM2, introns included, not only the 3.6 kb of exons.
