Labcorp Genetics (formerly Invitae), Labcorp RCV005198228 SCV005834870 uncertain significance Biotin-responsive basal ganglia disease 2024-12-21 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 51 of the SLC19A3 protein (p.Ile51Met). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with SLC19A3-related conditions (PMID: 26657515). 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 SLC19A3 protein function with a negative predictive value of 95%. 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.
