Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PM5PP3_ModeratePP5_Moderate
The NM_001370658.1(BTD):c.1309G>A(p.Val437Met) variant causes a missense change. The variant allele was found at a frequency of 0.00000248 in 1,614,086 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V437L) has been classified as Likely pathogenic.

Biotinidase deficiency Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 20, 2022 | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This missense change has been observed in individual(s) with biotinidase deficiency (PMID: 9396567, 28281033). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs146600671, gnomAD 0.0009%). This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 457 of the BTD protein (p.Val457Met). - |
