RCV000021937 | SCV001201601 | uncertain significance | Biotinidase deficiency | 2022-01-15 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 172 of the BTD protein (p.Asn172Ser). This variant is present in population databases (rs397514366, gnomAD 0.0009%). This missense change has been observed in individual(s) with biotinidase deficiency (PMID: 11313766). ClinVar contains an entry for this variant (Variation ID: 25017). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. |
Ambry Genetics | RCV002513164 | SCV003602268 | uncertain significance | Inborn genetic diseases | 2022-03-23 | criteria provided, single submitter | clinical testing | The c.515A>G (p.N172S) alteration is located in exon 4 (coding exon 4) of the BTD gene. This alteration results from a A to G substitution at nucleotide position 515, causing the asparagine (N) at amino acid position 172 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
