Variant summary
Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The NM_000128.4(F11):c.67C>T(p.Gln23*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000743 in 1,614,028 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 Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Q23Q) has been classified as Uncertain significance.

For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This sequence change creates a premature translational stop signal (p.Gln23*) in the F11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in F11 are known to be pathogenic (PMID: 23929304). This variant is present in population databases (rs768409400, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with clinical features of autosomal recessive factor XI deficiency (PMID: 21649796, 24112640). ClinVar contains an entry for this variant (Variation ID: 189122). -
