Polyglucosan body myopathy type 1 Uncertain:2

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 314 of the RBCK1 protein (p.Arg314His). This variant is present in population databases (rs759203606, gnomAD 0.01%). 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: 569612). 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 RBCK1 protein function with a negative predictive value of 80%. 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. -
