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 Likely_benign. Variant got -2 ACMG points.

PP2
Missense variant in the DNM2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 30 curated pathogenic missense variants (we use a threshold of 10). The gene has 14 curated benign missense variants. Gene score misZ: 3.4829 (above the threshold of 3.09). Trascript score misZ: 4.8575 (above the threshold of 3.09). GenCC associations: The gene is linked to 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.
BP4
Computational evidence support a benign effect (MetaRNN=0.1957084).
BP6
Variant 19-10772559-G-A is Benign according to our data. Variant chr19-10772559-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 246522.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Benign=1, Uncertain_significance=1}.
