Labcorp Genetics (formerly Invitae), Labcorp RCV003499925 SCV004292224 likely pathogenic Biotinidase deficiency 2023-06-23 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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. This missense change has been observed in individual(s) with biotinidase deficiency (PMID: 26810761). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 253 of the BTD protein (p.Pro253Leu).
