Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP3_Strong PP5

The NM_000128.4(F11):c.1289C>T(p.Ala430Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000479 in 1,461,748 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 (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A430S) has been classified as Likely pathogenic.

Genes affected

F11 (HGNC:3529): (coagulation factor XI) This gene encodes coagulation factor XI of the blood coagulation cascade. This protein is present in plasma as a zymogen, which is a unique plasma coagulation enzyme because it exists as a homodimer consisting of two identical polypeptide chains linked by disulfide bonds. During activation of the plasma factor XI, an internal peptide bond is cleaved by factor XIIa (or XII) in each of the two chains, resulting in activated factor XIa, a serine protease composed of two heavy and two light chains held together by disulfide bonds. This activated plasma factor XI triggers the middle phase of the intrisic pathway of blood coagulation by activating factor IX. Defects in this factor lead to Rosenthal syndrome, a blood coagulation abnormality. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM1: In a helix (size 3) in uniprot entity FA11_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_000128.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr4-186284244-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 291081.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.994
• PP5: Variant 4-186284245-C-T is Pathogenic according to our data. Variant chr4-186284245-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 11899.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr4-186284245-C-T is described in Lovd as [Pathogenic].
