Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 1P and 0B. PP2
The NM_004408.4(DNM1):c.1399C>T(p.Arg467Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000127 in 1,569,408 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. R467R) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Apr 23, 2024 | Variant summary: DNM1 c.1399C>T (p.Arg467Cys) results in a non-conservative amino acid change located in the Dynamin stalk domain (IPR000375) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The frequency data for this variant in gnomAD is considered unreliable, as metrics indicate poor data quality at this position. To our knowledge, no occurrence of c.1399C>T in individuals affected with Developmental And Epileptic Encephalopathy, 31 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 521971). Based on the evidence outlined above, the variant was classified as uncertain significance. - |
Developmental and epileptic encephalopathy, 31A Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 31, 2022 | ClinVar contains an entry for this variant (Variation ID: 521971). 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with DNM1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 467 of the DNM1 protein (p.Arg467Cys). - |
