RCV001236637 | SCV001409369 | uncertain significance | Duchenne muscular dystrophy | 2024-10-28 | 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 1719 of the DMD protein (p.Arg1719His). 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 variant has not been reported in the literature in individuals affected with DMD-related conditions. ClinVar contains an entry for this variant (Variation ID: 962729). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. |

Ambry Genetics | RCV003380920 | SCV004097145 | uncertain significance | Cardiovascular phenotype | 2023-08-31 | criteria provided, single submitter | clinical testing | The p.R1719H variant (also known as c.5156G>A), located in coding exon 37 of the DMD gene, results from a G to A substitution at nucleotide position 5156. The arginine at codon 1719 is replaced by histidine, an amino acid with highly similar properties. Based on data from gnomAD, the A allele has an overall frequency of 0.0011% (2/174237) total alleles studied, with 2 hemizygote(s) observed. The highest observed frequency was 0.0075% (2/26582) of Latino alleles. This amino acid position is well 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 alteration remains unclear. |
