Variant summary
Our verdict is Pathogenic. Variant got 19 ACMG points: 19P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Very_Strong
The NM_004408.4(DNM1):c.1075G>A(p.Gly359Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 13/20 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G359A) has been classified as Likely pathogenic.

Developmental and epileptic encephalopathy, 31 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 14, 2018 | This sequence change replaces glycine with arginine at codon 359 of the DNM1 protein (p.Gly359Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in individuals affected with early infantile epileptic encephalopathy (PMID: 28667181, Invitae). ClinVar contains an entry for this variant (Variation ID: 520737). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. For these reasons, this variant has been classified as Pathogenic. A variant that disrupts the p.Gly359 amino acid residue in DNM1 has been observed in an affected individual (PMID: 25262651). This suggests that it is a clinically significant residue, and that other variants that disrupt this residue are likely to be causative of disease. - |
