For these reasons, this variant has been classified as Pathogenic. This premature translational stop signal has been observed in individual(s) with biotinidase deficiency (PMID: 10801053, 17382128). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr57*) in the BTD gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BTD are known to be pathogenic (PMID: 20083419).

Record last updated Oct 08, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
