Variant summary
Our verdict is Likely benign. Variant got -3 ACMG points: 6P and 9B. PM1PM2PM5BP4_StrongBP6BS1
The NM_001927.4(DES):c.935A>C(p.Asp312Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000208 in 1,613,674 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D312N) has been classified as Likely benign.

not provided Uncertain:4
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | May 05, 2023 | Identified in individuals with HCM, DCM, or sudden unexplained death in published literature (Mook et al., 2013; Pugh et al., 2014; Sanchez et al., 2016; van Lint et al., 2019); however, several individuals harbored additional cardiogenetic variants; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; A different missense change at this residue (D312N) has been reported in the Human Gene Mutation Database and in published literature (Stenson et al., 2014; Taylor et al., 2007; Pugh et al., 2014; Holmstrom et al., 2021; Gonzalez-Quereda et al., 2020); This variant is associated with the following publications: (PMID: 24503780, 27930701, 29926427, 17325244, 30847666, 26807690, 23785128) - |
Uncertain significance, criteria provided, single submitter | clinical testing | Athena Diagnostics | Nov 03, 2022 | Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is higher than would generally be expected for pathogenic variants in this gene. (http://gnomad.broadinstitute.org) Computational tools predict that this variant is damaging. - |

not specified Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Mar 02, 2012 | p.Asp312Ala in exon 5 of DES: This variant is not expected to have clinical sign ificance because it has been identified in 0.3% (11/3738) of African American ch romosomes from a broad population by the NHLBI Exome Sequencing Project (http:// evs.gs.washington.edu/EVS; dbSNP rs148947510). - |
DES-related condition Benign:1
Likely benign, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Sep 20, 2022 | This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). - |
Cardiovascular phenotype Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 13, 2020 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
