RCV000427179 | SCV000780074 | uncertain significance | not provided | 2018-05-21 | criteria provided, single submitter | clinical testing | A variant of uncertain significance has been identified in the DNM1 gene. The I120V variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The I120V variant is observed in 1/8704 (0.01%) alleles from individuals of African background in large population cohorts (Lek et al., 2016). The I120V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. In-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. Based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. |

RCV001851030 | SCV002273569 | uncertain significance | Developmental and epileptic encephalopathy, 31A | 2024-02-08 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 120 of the DNM1 protein (p.Ile120Val). This variant is present in population databases (no rsID available, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with DNM1-related conditions. ClinVar contains an entry for this variant (Variation ID: 377330). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DNM1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
