Variant summary

Our verdict is Benign. Variant got -11 ACMG points: 1P and 12B. PP2BP4_StrongBP6_Very_Strong

The ENST00000634267.2(DNM1):c.2545G>A(p.Gly849Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000858 in 1,595,998 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 6/8 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G849E) has been classified as Uncertain significance.

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 Benign. Variant got -11 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: 5.1645 (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.

BP4

Computational evidence support a benign effect (MetaRNN=0.0040893257).

BP6

Variant 9-128254660-G-A is Benign according to our data. Variant chr9-128254660-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 476065.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
