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.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DNM2. . Gene score misZ: 3.4829 (greater than the threshold 3.09). Trascript score misZ: 4.8575 (greater than threshold 3.09). The gene has 30 curated pathogenic missense variants (we use a threshold of 10). The gene has 14 curated benign missense variants. GenCC has associacion of the gene with fetal akinesia-cerebral and retinal hemorrhage syndrome, Charcot-Marie-Tooth disease dominant intermediate B, hereditary spastic paraplegia, Charcot-Marie-Tooth disease, autosomal dominant centronuclear myopathy, autosomal dominant Charcot-Marie-Tooth disease type 2M.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.875
