Genes affected
DNM1 (HGNC:2972): (dynamin 1) This gene encodes a member of the dynamin subfamily of GTP-binding proteins. The encoded protein possesses unique mechanochemical properties used to tubulate and sever membranes, and is involved in clathrin-mediated endocytosis and other vesicular trafficking processes. Actin and other cytoskeletal proteins act as binding partners for the encoded protein, which can also self-assemble leading to stimulation of GTPase activity. More than sixty highly conserved copies of the 3' region of this gene are found elsewhere in the genome, particularly on chromosomes Y and 15. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PP2
Missense variant in the DNM1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 39 curated pathogenic missense variants (we use a threshold of 10). The gene has 46 curated benign missense variants. Gene score misZ: 5.1795 (above the threshold of 3.09). Trascript score misZ: 5.021 (above the threshold of 3.09). GenCC associations: The gene is linked to developmental and epileptic encephalopathy, 31, undetermined early-onset epileptic encephalopathy, developmental and epileptic encephalopathy 31B, developmental and epileptic encephalopathy, Lennox-Gastaut syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.752
BP6
Variant 9-128234043-G-A is Benign according to our data. Variant chr9-128234043-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 476059.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
