RCV000669098 | SCV002214270 | pathogenic | Biotinidase deficiency | 2021-11-14 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the BTD protein in which other variant(s) (p.Leu498Phefs*13) have been determined to be pathogenic (PMID: 17382128, 19728141, 29359854). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 553614). This variant has not been reported in the literature in individuals affected with BTD-related conditions. This variant is present in population databases (rs749162799, gnomAD 0.02%). This sequence change creates a premature translational stop signal (p.Ile334Serfs*19) in the BTD gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 210 amino acid(s) of the BTD protein. |
3billion | RCV000669098 | SCV002318765 | likely pathogenic | Biotinidase deficiency | 2022-03-22 | criteria provided, single submitter | clinical testing | Frameshift: predicted to result in a loss or disruption of normal protein function through protein truncation. Multiple pathogenic variants are reported in the predicted truncated region. This variant has been reported as pathogenic (ClinVar ID: VCV000553614). The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.0000119). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. |
