RCV005198251 | SCV005834611 | pathogenic | Biotinidase deficiency | 2024-10-21 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 65 of the BTD protein (p.His65Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with biotinidase deficiency (PMID: 19757147; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. 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 expected to disrupt BTD protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. |
