Ambry Genetics | RCV000620321 | SCV000736214 | uncertain significance | Cardiovascular phenotype | 2016-01-14 | criteria provided, single submitter | clinical testing | The p.R1955H variant (also known as c.5864G>A), located in coding exon 41 of the DMD gene, results from a G to A substitution at nucleotide position 5864. The arginine at codon 1955 is replaced by histidine, an amino acid with highly similar properties. This variant was previously reported in the SNPDatabase as rs200455300. Based on data from the 1000 Genomes Project, the A allele has an overall frequency of approximately 0% (0/503) total male alleles studied. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear. |

RCV000630525 | SCV000751487 | uncertain significance | Duchenne muscular dystrophy | 2025-01-23 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1955 of the DMD protein (p.Arg1955His). This variant is present in population databases (rs200455300, gnomAD 0.008%). This missense change has been observed in individual(s) with DMD-related conditions (PMID: 37510298). ClinVar contains an entry for this variant (Variation ID: 518775). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt DMD protein function with a negative predictive value of 95%. 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. |
