Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PM5PP3PP5_Moderate
The NM_000133.4(F9):c.148G>A(p.Gly50Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000365 in 1,096,855 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 1 hemizygotes in GnomAD. 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. G50A) has been classified as Likely pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 13, 2022 | ClinVar contains an entry for this variant (Variation ID: 454495). For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt F9 protein function. This missense change has been observed in individuals with mild hemophilia B (PMID: 8091381, 8594556, 19699296, 27213901; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 50 of the F9 protein (p.Gly50Ser). - |
