Invitae RCV001065601 SCV001230567 uncertain significance Beta-D-mannosidosis 2022-10-03 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 734 of the MANBA protein (p.Arg734His). This variant is present in population databases (rs143630504, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with MANBA-related conditions. ClinVar contains an entry for this variant (Variation ID: 859480). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MANBA 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.
GeneDx RCV003328651 SCV004035672 uncertain significance not provided 2023-03-10 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
