Invitae RCV001203912 SCV001375094 pathogenic Biotinidase deficiency 2022-02-17 criteria provided, single submitter clinical testing This variant disrupts a region of the BTD protein in which other variant(s) (p.Ser311Argfs*23) have been determined to be pathogenic (PMID: 9396567, 10400129, 12359137, 17185019, 22698809, 25174816). 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: 935341). This variant has not been reported in the literature in individuals affected with BTD-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ile115Phefs*44) in the BTD gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 429 amino acid(s) of the BTD protein. For these reasons, this variant has been classified as Pathogenic.
