Labcorp Genetics (formerly Invitae), Labcorp	RCV000170498	SCV000656484	pathogenic	Developmental and epileptic encephalopathy, 31A	2023-08-29	criteria provided, single submitter	clinical testing	This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. 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) performed at Invitae indicates that this missense variant is expected to disrupt DNM1 protein function. ClinVar contains an entry for this variant (Variation ID: 280148). This missense change has been observed in individual(s) with epileptic encephalopathy (EE) and West syndrome (PMID: 25262651, 26611353, 29314763). In at least one individual the variant was observed to be de novo. This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 237 of the DNM1 protein (p.Arg237Trp).

Pediatrics, MediClubGeorgia	RCV000170498	SCV001468641	pathogenic	Developmental and epileptic encephalopathy, 31A	2021-01-03	criteria provided, single submitter	clinical testing	This sequence change replaces arginine with tryptophan at codon 237 of the DNM1 protein (p.Arg237Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. The variant is absent in population databases. This de novo variant has been reported in individuals affected with epileptic encephalopathy (EE) and West syndrome. It has also been reported in an individual with EE who inherited the variant from an unaffected parent (somatic mosaic). SIFT - deleterious, PolyPhen - Probably Damaging, FATHMM pred - Damaging, MutationAssessor - High, MutationTaster - diseases causing, Provean - Damaging, MetaSVM - Damaging. The parents were also tested - not detected. On Clinvar this variant is submitted as Pathogenic.
