Description

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 62 of the BTD protein (p.Val62Met). This variant is present in population databases (rs397507170, gnomAD 0.006%). This missense change has been observed in individual(s) with biotinidase deficiency (PMID: 11313766, 15060693, 17185019, 22698809). ClinVar contains an entry for this variant (Variation ID: 38487). 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 expected to disrupt BTD protein function. For these reasons, this variant has been classified as Pathogenic.
