RCV001070144 | SCV001235357 | uncertain significance | Polyglucosan body myopathy type 1 | 2022-07-26 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 269 of the RBCK1 protein (p.Asp269Glu). This variant is present in population databases (rs111283441, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with RBCK1-related conditions. ClinVar contains an entry for this variant (Variation ID: 863224). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glutamic acid 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. |

RCV001070144 | SCV001468358 | uncertain significance | Polyglucosan body myopathy type 1 | 2021-03-30 | criteria provided, single submitter | clinical testing | RBCK1 NM_031229.3 exon 7 p.Asp269Glu (c.807C>G): This variant has not been reported in the literature but is present in 0.01% (4/26108) of Latino alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/20-401565-C-G?dataset=gnomad_r2_1). This variant is present in ClinVar (Variation ID:863224). This variant amino Glutamic acid (Glu) is present in several species including mammals and is not well conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. |
